Pros: "The Pilot kept us safe XD"
Cons: "Pretzels!!! Instead of those cookies, bleh"

Pros: "Helpful crew"
Cons: "There was a delay. Moved my selected asile seat to a middle seat without notice."

Pros: "Nothing"
Cons: "We were delayed for nearly 4 hours and were stuck on the plane while being lied to telling us “we’re up next to get de-iced then we can take off” then one hour goes by and the same announcement. Will never fly Alaskan again."

Pros: "Great Service"

Pros: "On time departing and landing."

Pros: "Nice"

Pros: "Crew was nice and helpful Comfortable Entertainment"
Cons: "Flight delayed 1 hour"

Pros: "All aspects were very good. Non-stop flight to STL a very good option for travel."

Pros: "The crew on both flights were excellent"
Cons: "I didn’t like the fact that when we returned to St Louis our luggage was not here. And to make matters worse there were no Alaska agents to assist us in any shape form or fashion. I made a call and left my name and flight information and hope someone will call me tomorrow with an update on my luggage and have it delivered to my home. Because as of right now we have been traveling almost 24 hours from Alaska to St Louis. Please call me if you need any additional information."

Cons: "I put my bag on recheck at SFO and had four hours before my flight to Portland. My bag did not show up. Not sure who screwed that up."

Pros: "Great staff - fun and casual . - price was great"

Pros: "Great newer 737-900"
Cons: "Temperature was too warm for the entire flight. Several asked for more air conditioning"

Pros: "On time departure and arrival, friendly and helpful crew."
Cons: "I tried to get an aisle seat and was told that was what I was assigned when I checked in at Beijing. Even though it was in the Premium section with extra legroom, a middle seat is difficult for a 5' 11" person, especially after flying for as many hours as I flew. I was constantly bumping shoulders with people in the aisle and window seats."

Pros: "I did not feel well on this flight and had a great experience. The crew was very helpful and kind and attended to my needs."

Pros: "Punctual, professional and comfortable. This airline has never disappointed me. I appreciate the seat availability and the staff are always so very pleasant. Well done."
Cons: "My return flight has a child seated behind me. Not great."

Pros: "Price quick boarding. Great staff comped my checked bag. Not overbooked. Prompt beverages. Love it!"
Cons: "Nothing! I almost even signed up for the credit card lol"

Pros: "i got a good window seat"
Cons: "didnt like the hour delay, but what can you do"

Pros: "the flight attendants were courteous and kind"
Cons: "pilots intercom voice was muffled and rapid"

Cons: "The flight was delayed 1 1/2 hrs waiting for a crew member to arrive! The flight attendant was unpleasant."

Pros: "Boarding the flight was easier than most flights that I have been on and the crew was fairly helpful when it came to needing help with anything."
Cons: "The WiFi that is provided is horrible. One second it would work and the next it would not. Not a lot of choices when it comes to food for purchase on the flight and you get tired of the same thing being offered every single flight."

Pros: "It was a direct flight and quick boarding. Pilots did a great job being on time...Alaska Airlines made up 45 mins to and was on time from Portland, Or..."

Pros: "Everything went smoothly, and the crew was very friendly and helpful."

Cons: "Na"

Cons: "lost my baggage, huge pain in the butt. At least they said they'd cover everything. We'll see what happens."

Pros: "Customer service the people are always amazing! My 6 yr old daughter and I had assigned seats apart and they had no problem getting us together I appreciated it. Also when we had a delay they gave us food vouchers which helped me and my children out."
Cons: "3 hr delay but glad they got it all fixed. Also a little confusion when boarding they left out a few rows and skipped us but no biggie we all get on the plane."

Pros: "I love the boarding process. It only makes sense to board the back of the plane first. Finally! They have nice size overhead bins. Love the charging ports in the back of the seats. It seems like someone finally thought through the flight process. Even with a little turbulence the landing was smooth and just a little early."
Cons: "Not their fault, but not a fan of long layovers. Anything over an hour to an hour and a half is a pain."

Pros: "Flight got cancelled, idiots"

Pros: "arrived very close to on time staff were quite pleasant"
Cons: "small child (3-4y) climbing on seats - standing with one foot on each seat , straddling the aisle, and walking in aisle - at times when both seat belt sign was on and off (zero attempt by parents to have them stop - laughing at the antics and/or dad playing video games) I could not get the gogo app to work to watch the "free streaming" movies"

Pros: "the digital boarding pass is great. The food tasted good but was costly."
Cons: "it was hot on the plane. a 4 hour flight and you have to pay for food?"

Pros: "Nice leg room, Flight Was Also Early"

Pros: "I did not eat on flight , just had the drink that was offered. Also did not use the entertainment offered. It was nice that both were available."

Cons: "no chargers"

Pros: "Completely full flight but loaded quickly and attendants were great!"

Pros: "The crew was great! Humorous, courteous, and helped passengers feel relaxed. Coffee and biscoff cookies are awesome. Also enjoy when they come by a second time to see if you'd like more to drink."
Cons: "Seating was tight and uncomfortable"

Cons: "Food."

Pros: "Loved the charging ports..My fruit and cheese tray was actually fabulous. Boarding was done fairly quickly and we even left a few minutes early."

Pros: "Everything was wonderful. I especially enjoyed the free wifi so I could text my husband to let him know that I was going to be landing a little bit early!"

Pros: "The flight from St. Louis to Seattle was delightful. The crew were top notch and provided good food, snacks & drinks. All of which I endulged. We landed on time..... but that's where the good times come to an end."
Cons: "55min wait on the after landing. Another hr to get bags. Roughly 2 hr delay. Also, having the return to SeaTac after taking off due to mechanical failure. Rrrr! 4 cancellations thanks to the snow and the port of Seattle with their "Regulations""

Pros: "it is too short time to catch this flight between two flights.so i didn't catch it,but they give next flight to stlouis,unfortunately the flight time is too late.hope next time can have a longer time between the two flights.because they saled together,it is good to think about the foreign passengers."

Pros: "Staff and crew were very friendly and accommodating. Flight was good and on time."
Cons: "I had arrived from Ft. McMurray more than 3 hours before my connection, but was was paged for a search just 30 minutes before my flight boarded. Delays in security meeting me almost made me miss my flight. I didn't understand why they waited so long to do the search. It should have been done when I first got there."

Pros: "Having an exit row"

Cons: "The check in process was cumbersome with being able to partially get checked in at a computer kiosk and then having to wait in line to see an agent while other people are jumping the queue and not having to wait... then having stood in line for 10 minutes an agent tells you that you could have been in the "fast" lane... but there is no or little signage indicating which line you should be in.... that's frustrating. Don't expect your customers to be unconsciously aware of all of your convoluted business practices... put some signs out... we at least like a hint. Other than that, for air travel it was a very good experience."

Pros: "Comfortable aircraft. Makes sense to board back of plane first"
Cons: "I was offered water, wine or orange juice but told there wasn't time to offer full beverage options because the flight wasn't long enough. Though the cart was fully stocked. How could it take more time to pour ginger ale than water? Made no sense."

Pros: "Smooth, clean, on time, ease of all!"

Pros: "It was great"

Pros: "Everything was great!"

Pros: "I was able to get an earlier flight."
Cons: "Did not buy food. Don't think I was offered tablet for movie."

Pros: "Roomie and comfortable seating!"
Cons: "Nothing. I would recommend AK"

Pros: "The attindent kept people seated till we stopped"
Cons: "The seats wouldn't recline."

Pros: "Service was fast"
Cons: "Better seats"

Pros: "Nothing"
Cons: "Proper communication"

Pros: "non stop flight"
Cons: "Crowded, small plane. No air after people had boarded while fuel was being replenished (dangerous?), sitting at gate for 20minutes. This, after a 2 hour delay. Then a rough landing in Minneapolis- plane brakes sharply and suddenly, shuddered to a taxi rate of speed. simple snacks, not very good."

Pros: "Nothing"
Cons: "Worse experience ever, flight delayed, lost connection, many hours in phone trying to fixed and anyway lost the flight, spent so many time at the airport with the front desk so disappointed"

Cons: "You guys didn't allow me to get in this plane and i missed my flight."

Cons: "Plane had to divert from Salt-Lake City due to a storm. My son 17 years old traveling alone once in Salt-Lake City should have been given priority for an overnight stay instead of sleeping on an airport bench! Dinner + Breakfast vouchers would also have been nice compared to the 15$ food voucher..."

Pros: "Our flight crew were great. Pilots were great too."
Cons: "I missed my connection due to weather in Minneapolis. Was diverted into Milwaukee, but nope we are diverted to Chicago, but wait no we go to Milwaukee. Deboard into a close gate area. Rest rooms were closed. Then once refueling is done get back on and make Minneapolis at 12:15 am. Connection missed"

Pros: "The flight attendants were amazing. 12 people had a connecting flight and they brought a shuttle bus. You dont see that kind of service any more 10 stars for that"
Cons: "Super small plane."

Pros: "The overall experience on the flight was quite pleasing. The flight crew created a warm atmosphere on what was a very cold morning. Seating was not the most comfortable but the wasn't unbearable."
Cons: "Delta should have a better food menu for those early flights unless the motive is to encourage everyone to eat an organic and wholesome meal prior to boarding, something we all should be doing."

Cons: "No food on board and we were hungry"

Pros: "Friendly crew."
Cons: "Slow boarding."

Pros: "Crew was friendly!"
Cons: "Plane wasn’t clean"

Pros: "Flight crew was excellent. We had the emergency exit row so leg room was awesome! Kind bar and soda we good."
Cons: "Flight delay due to the older aircraft and lack of a pilot that knew how to fly it. Bathroom needed some tending to"

Pros: "Equipment felt a bit dated. No entertainment system, which was fine with me. Skipped the offered snack. Just had water. Flight was onntime."

Cons: "Customs massively backed up. Somewhat disorganized"

Pros: "On Time. Nothing else to say,"

Pros: "Friendly, leg room, on time."

Pros: "I love the in-flight movies!"
Cons: "This wasn't pertaining to the flight or airline; but the TSA line was ridiculously slow."

Pros: "Flight went off pretty well. On time no complaints."
Cons: "Somewhere somehow you need to know that, although partners, Delta and West Jet do not share computer systems and that they are two completely different airlines. This affects ,sometimes, how luggage is handled especially when you land in another country and you have to manually transfer your own - and nobody tells you. You actually change airlines. Itinerary implies West Jet controls the entire thing. Not the case. Better job economic explaining what to With luggage and that, while itinerant implies 1 airline, they are only partners and should be treated separately."

Cons: "Direct flight, on time arrival"

Pros: "i fell asleep until we arrive to STL."

Pros: "Delta flew their way back into my heart this time around"

Cons: "have to wait 2 days for the flight, so i would say that's a pretty objective zero rating."

Pros: "Staff, Ease of boarding"
Cons: "Bring back in flight meals, please"

Cons: "They had to change tires before we lelt in Toronto. And we spent more than one hour on the tarmac."

Cons: "Temperature was too cold"

Pros: "The food"
Cons: "No entertainment"

Cons: "Bad"

Cons: "West Jet gave me a "fake" ticket delta would not let me board missed the flight I had to wake up at 3am to catch. This is after I finally made it to my hotel last night at 11:30 pm. This is completely unacceptable. NEVER AGAIN IN MY LIFE WILL I EVER FLY WITH THIS COMPANY!!!!"

Pros: "The flight attendants were great! Super friendly and helpful with everything!"
Cons: "I'd love slightly larger snack portions."

Pros: "Staffing was great!"
Cons: "The fact is that it is illegal to pack Sardines at compact as you are packing us on your aluminum cans."

Pros: "The flight being on time, friendly staff, clean aircraft.i"
Cons: "It was a morning flight from Toronto to Omaha via Minneapolis and unfortunately coffee wasn't served. Or maybe it got over."

Pros: "My first and last time flying Delta! Everything that could have went wrong, did in fact go wrong. We were re-booked on connecting flights different then the one we originally booked and weren't even notified. They have a Delta app, but it doesn't even work right. Unless you physically go to the gate to check to see if the flight is on time, that is the only was to find out if you are re-booked onto a different flight or not. I have never flown an airline that re-books you on a different flight when they feel like it. I wouldn't recommend Delta Airlines to my worse enemy!"

Pros: "For a short-haul flight on a small CRJ, it was the most pleasing and comfortable flight. No delays and everyone was pleasant from ground staff to flight crew."

Pros: "Crew smiling at the end of the flight."
Cons: "Cheap coffee (although it says Starbucks, I have tried better)."

Cons: "Please review the message I sent concerns Atlanta hartsfield."

Cons: "I thought I stated this before about the flight (5), Treatment (5) all the rest (5), but Atlanta Airport does not support disabled people using scooters to get from one plane to another. With more people using these, only a matter of time until a reporter males this an ISSUE. Meanwhile I will make every effort NOT to use ATLANTA HARTSFIELD. This includes my wife, also using a scooter."

Cons: "I showed up 2 hrs before the flight. Was told the flight from Toronto to Minn was delayed 30 minutes and go stand in line to speak to an agent. There were approx 20 in line yet only 2 gate agents at 4:30pm. One of the gate agents kept helping the Premium members and bypassing the standard line. The other agent was in a coma as his average person at counter was 10 min. Finally get to counter and they hand me a boarding pass going via Salt Lake in 30 minutes. But has a 3 hrs layover in SL. I then get to US Custom check for US residents re-entering and the line was a good 30 minute wait. You would think the Delta folks would have accounted for that line. I had to ask everyone in front of them if I could skip in front as the plane was now departing in 10 min. I had to then run on a bum knee and was the last to board. The agent at gate was saying we were calling your name but did they think I could have been stuck in customs? On that short of a window they should have walked me through Customs to make sure I got on a flight they wanted me to take versus my scheduled flight."

Pros: "Direct flight to JFK using Delta. Was not aware that I was NOT flying on West Jet therefore encountered problems searching for a way to check in online. Ground crew airport check in at the Delta counter and at the Boarding gate was helpful and efficient. However request for Special Assistance in Toronto was poorly handled. We did not accept the conditions offered to us as one wheel chair operator had to push 3 passengers and I had to wait for him to return to me after two people were brought to their gates. My Husband had to wheel me in to my gate."

Pros: "Excellent flight. Nice new aircraft."

Pros: "Quick and convenient"
Cons: "Comfort and food was lacking"

Cons: "I wasn’t able to choose a seat"

Pros: "Smooth process, nice plane, amicable staff"

Pros: "Service was very good."
Cons: "Nothing."

Cons: "I wish there were more food options"

Pros: "Arrived earlier than scheduled."

Cons: "Food options are terrible especially when you pay for them. Better quality needed"

Pros: "price efficiency"
Cons: "gate change last minute"

Pros: "Mate"
Cons: "Late"

Cons: "Way too cramped. Only 1 washroom."

Cons: "Because of the discounted fare I was placed in rear seating at the very back of the plane and to change seats was to cost me $14"

Pros: "Smooth trip."
Cons: "No one would get a wheelchair to get to cart that was on different floor. Driver didn't volunteer to carry bags to cart."

Cons: "No information"

Pros: "On time, free coffee, free pretzels"
Cons: "Going home."

Cons: "Booked our seats 24 hours in advance and could not get seats together. Airline expects us to pay extra for reasonable expectations as that"

Pros: "The crew were very amiable and one member in particular was quite funny during the seat belt demonstration. First one I've paid attention to the entire time."
Cons: "Plane was freezing cold and seats were quite uncomfortable."

Pros: "Talia is an excellent stewardess—She takes good care of people"

Pros: "Haven't taken it yet"
Cons: "Well I'm not on the plane yet cause you left.me stuck in Vancouver"

Pros: "There was a cute doctor and someone made a joke about the movie Alive. That was funny."
Cons: "There was a sick lady and she wouldn't stop coughing. That was gross"

Pros: "Comfortable seats"
Cons: "Late departure"

Pros: "Some of the people who helped with wheelchair assistance for my dad were kind."
Cons: "1. I previously asked for wheelchair assistance for my father and when we dropped off our bags the agent said she would get someone and told us to sit in the waiting area. After five minutes no one came so I went to the assistance desk and they said they hadn't been informed so they sent someone right away. If I hadn't been there to ask, I don't know how long my mom and dad would have sat there. 2. The man who wheeled my dad to the gate was very nice and he said he arranged for all of us to sit together, which was nice because I wasn't able to sit with my parents since we weren't able to choose the same row when we booked. When we boarded, we found out that the seats hadn't been changed, and the person who previously booked the seat beside my parents refused to move so I sat in the row beside them. These problems were minor but they highlighted a lack of communication between staff and the attendant dealing with us wasn't the most friendly either. I used to fly westjet in the early days when I still lived in Canada and I've noticed that the level of service has gone down. Thank you for allowing me the opportunity and space to comment. Asunción Perez"

Pros: "Staff and aervice was great! No complaint!"
Cons: "We had to put our carry on bags a little far away from our seats"

Pros: "I just love WestJet"

Cons: "Transferring between distant terminals in LAX was a pain. I'm glad that I had a long layover between flights to make the journey that required leaving and re-entering security."

Pros: "Not cold, not noisy aircraft"

Pros: "Landed 10 minutes early. Good landing in tough conditions"

Cons: "To the best of my knowledge I paid for a window seat on my trip to Montreal. It was the only option I elected to pay for, yet, I found myself in the middle seat. A personal life lesson we’ll learned and an experience to be remembered & considered, under advisement, on any future bookings."

Cons: "Small!!!"

Pros: "The people that work for WestJet are exceptional! I find everyone there is knowledge, helpful and happy. The last one is why I fly with WestJet. Its a real treat to be so well taken care of."

Pros: "I upgraded and that was definitely worth it."
Cons: "I don't like 2.5 hour flights in general. Just long enough to be annoying. But that has nothing to do with you and your airline."

Cons: "Not one complaint"

Pros: "The Pilot explained his Procedures thoroughly."
Cons: "Same as above."

Cons: "Being late into LA"

Cons: "Got there 2 minutes after check in closed and wouldn't let us fly"

Cons: "My luggage did not make it."

Pros: "Smooth, friendly and cost effective."

Cons: "No entertain system"

Pros: "Nice Staff. Easy process."

Cons: "cabin was too hot"

Pros: "Drinks and snacks several times! Lots of movies!"

Pros: "Comfy legroom (for someone who is 6'5") and comfortable seat."
Cons: "Late take off, late arrival at gate, late baggage delivery."

Pros: "Staff were very good"
Cons: "No frills flight, their booking and computer systems are not good."

Pros: "Everything was on time considering the heavy Holidays travels."

Cons: "Food quality"

Cons: "Seat space"

Cons: "Better communication about handicap persons. I called twice and notified two people about my mom and her wheelchair but no one tells the gate to put a ramp up to the regional jet on the tarmac. Three ring circus as usual ."

Cons: "The wifi signup process not seemless with Android."

Cons: "Make seat available for two of us together not every one in a deferent row"

Pros: "Crew friendly and accommodating, even on short flight"

Pros: "No"
Cons: "No"

Pros: "Service was good"
Cons: "Nothing"

Cons: "6 hour mechanical delay"

Cons: "First flight delayed 45 min, then cancelled. 2nd flight 3 hrs later."

Cons: "Un necessary delays from start to baggage pickup"

Pros: "The crew was great and made light of a relatively tense situation. This was a connecting flight for many passengers which was delayed so many of us were missing our connections. The crew still did a great job keeping everyone comfortable and boarding us quickly."
Cons: "Unfortunately our plane was grounded in Chicago before our leg of the trip even began. By the time it arrived in YYZ many of us would already be missing connections. Due to a smaller plane we have to stow most of our carry on below which caused a bit of chaos while disembarking trying to retrieve bags and hustle to the next flights. Since I knew before leaving YYZ we were quite delayed my husband drove to ORD to pick me up instead of waiting 24hr for the next flight to St. Louis. It added 8 hours of driving for him to an already long day but we made the best of it."

Pros: "Clean, Friendly flight attendant"
Cons: "I don’t understand how a brief meaning less than 30 minutes thunderstorm can cause a five hour delay. Every time I take the route from DCA to STL American is always really late"

Pros: "crew was pleasant"

Pros: "Great pilot. Outstanding control over the plane. Arrived an hour and a half before originally forecasted three days prior."

Cons: "Flight was delayed almost two hours due to crew staffing issues."

Pros: "good price and a good route"
Cons: "This turned out to be a 'code share' flight operated by American Airlines. As such, neither Qantas nor American Airlines would allow me to buy premium seats so we could have extra leg room. They said the 'code share' blocks seat sales! Be ware Also found out that American Airlines does not serve meals on flights from Toronto to LAX. I was told they only serve meals on "international flights" but that I could buy a sandwich or snack. Unfortunately they only had 4 sandwiches on board , which sold within the first 2 rows of the plane!"

Pros: "Boarding was a breeze"
Cons: "N/A"

Cons: "There was a glitch in the system with our boarding passes. It got sorted out but was just kind of weird."

Cons: "It was nice. And boarding was good too."

Pros: "This flight is the normal nonstop from Mia to StL. The seating is tight but not completely uncomfortable."
Cons: "I just had knee replacement 4 1/2 months ago. It was difficult to fully extend my leg under the seat in front of me because the space between rows has shrunk to include more seating."

Pros: "The seats were comfortable and the boarding process was very well organized."
Cons: "The plane had a very good entertainment system with a lot of good movies, but the flight had no earphones available, so only the passengers that had their own ear/headphones could use it. Other than that, the flight attendants were not kind in any way and items present in the onboard menu, were not available, as I asked for Pringles and there was none. I did not see anybody eating some food in this flight, other than the mini pretzels served. How a 3hour flight arriving at 09 PM, had no food onboard?"

Cons: "Staff seemed tired with some minor conflicts between them at Toronto gate"

Cons: "The seats are hard although spacious for a 3 set row."

Cons: "I hated the waiting area at Pearson. I hated the temperature and how tiny the seats are. Was so hot and absolutely miserable."

Pros: "It was easy to travel"

Cons: "Too many delays. Having to de-board after boarding."

Cons: "Plane was not board on time. Delayed taking off."

Pros: "The middle seat was empty I had an aisle seat. That was wonderful."
Cons: "No wifi screens for books or movies but I had my iPhone."

Pros: "Great staff."
Cons: "The hour delay due to maintenance and fueling."

Pros: "I liked having a window seat."
Cons: "My screen was broken, so for 6 1/2 hours, I was unable to watch any movies and didn't see the safety video either."

Pros: "On time"
Cons: "Boarding numbers"

Pros: "My neighbor."
Cons: "We sat on the tarmac for over an hour for no apparent reason."

Cons: "Seemed to be an unnecessary delay in departing a half hour late"

Cons: "I nearly missed my flight because I did not have a seat for a flight that I bought a ticket for at full price. Which, would lead one to believe that I would have a seat on said flight. However, coming to the gate an hour before boarding the personnel working gate the said he was having computer difficulties and could not get me a seat and it would be 10 min. I continued to return till boarding to find out I had no seat and I was on standby. Upon going to customer service they replied the airline oversold tickets and every airline does this as if to make this practice ok. Well being in sales myself and if I were to sell x amount of product to one customer ( or several) I better make sure I have it all there to deliver. People rely on you schedule wise. It nearly shot a meeting I had to make in the foot. Very disappointed with the airline and the way things were handled."

Cons: "Forced to check my carry on. Took 30min for the bags to come out on the carousel. Which is why i never check my bag."

Cons: "The fact the flight was delayed for 5 hours due to weather."

Cons: "Again out of snacks and she skipped our row for drinks. Again small issues but what else are they doing?"

Pros: "It took off on time and life was good."

Pros: "Crew is great!"
Cons: "Delay"

Cons: "Air Canada changed our seating on day of travel. I had ordered tickets over a month in advance and scheduled seating for my wife and I on our 3 leg flight. Air Canada changed our seating on the 1st and 3rd leg and we were no longer sitting together."

Pros: "The food was excellent, jet airways was Rocking. Airfrance had excellent service."

Pros: "Nice crew."
Cons: "Would have liked some better movie choices."

Pros: "Nothing"
Cons: "2 hour delay because of rain west jet and porter were on time but air canada delayed My seat was apparently broken had a window seat with no one else in my row and then I was placed ina Center seat although other options were open The attendant comes on the air and says they need to manually start the engine one by one because the electric start to make it easy was not working All and all not a pleasant experience at all"

Pros: "Very roomy, comfortable seat, great service and a pretty decent meal for a two hour flight. The heated nuts are a nice touch."

Pros: "Getting off the plane."
Cons: "My flight was delayed and that's understandable, my luggage however was lost and I was not fully informed about the delayed luggage process with Air Canada. Now I will be at least 4, maybe even 5 days without my luggage at an international destination."

Pros: "Flight crew was vey nice and flight was on time."

Pros: "Not a lot"
Cons: "Poor aircraft, uncomfortable seats, not recommended."

Pros: "Crew was very good."
Cons: "In-flight video (via app) was slow and unreliable. Seat comfort was lacking."

Pros: "Flight was quick, service was great, clean lavatories."
Cons: "Would've appreciated more legroom, but the same can be said for just about any airline."

Pros: "It was a mostly empty flight, so there was plenty of space."
Cons: "The only bathroom was locked for landing, which I understand is a policy, however a woman sitting next to me REALLY had to go, and being at the back of the plane while everyone was leaving, could not go ask for it to be unlocked. I felt bad for her... Also, it was not clearly written or easy to understand where our gate was at Cleveland Hopkins. It was a small flight, but it could have been clearer."

Pros: "air canada quickly changed me to another flight when mine was delayed but I had to ask for that, they did not offer."
Cons: "delay was long and I wasn't offered a switch to another flight. had to ask myself for it."

Cons: "We did not make this flight due to the first flight being over an hour late. This caused us to miss our connection to St. Louis. While they rerouted others on the flight, they did not reroute us because we didn't check any luggage! Their reasoning was we had a chance to make the connection. But they made us wait in a line for 10 minutes to be told that despite our requests to go to the gate. By then it was too late. We then had to fly stand by to Chicago and stand by again to get to St. Louis."

Cons: "Flight was late. The status screens in the Toronto airport depicted incorrect information."

Pros: "We were able to switch to an earlier flight. gate agent was very helpful"

Pros: "The crew was nice and understanding"
Cons: "I was stuck up against the back galley with no armrest on the aisle but that was only the beginning when the guy in front reclined his seat the seat back it was dangerously close to my head. In the event of turbulence it would have been easy to sustain a massive blow to the head from the seat in front of me during a whiplash type motion. The person that approved this seating arrangement should be terminated."

Pros: "The crew was great"
Cons: "Broken toilet for this flight"

Pros: "The food was airline food, the movies worked"
Cons: "Given customs form in German, when asked for English flight attendant said they were out. asked another later and she brought it immediately. After herded through security (again) and customs, with no explanation on what to expect, our connecting flight's gate was in the basement. It looked like a third world bus station. No place to sit, totally packed, could not understand announcements, only bagel place to eat that was out of most everything. I will avoid Air Canada and Toronto airport if at all possible."

Pros: "Crew was very nice"
Cons: "n/a"

Pros: "Quick flight and smooth ride. Same for boarding and exiting."
Cons: "Entertainment was not working well. Headphone jack broken and on board screen was spotty. Crew members did not offer anything to soften the situation."

Pros: "Air Canada is a wonderful airline for the price!! Seats are comfy staff is excellent. Food is decent."
Cons: "Food wasn't great but what do you expect it's on a airplane."

Cons: "People could be friendlier"

Pros: "Much better than the Air Canada flight from Europe. There was a good selection of movies and easy to use. For a short flight, they packed food, drink and a movie. Family enjoyed this flight."

Cons: "Six hours stuck at an airport with no where to get decent food and ended up sleeping on the floor. There should not be a stop to flights at night time."

Cons: "Delays on every leg of our flight. Missed our evening flight to USA and had to spend the night in Canada to fly out the next day. Desk agent service was atrocious!"

Pros: "Clean aircraft."
Cons: "Seats being marked @ $ 16 and $42 upto 24 hours before flight"

Cons: "We got a hotel in St. Louis so we'd be plenty early for our morning flight. Got to the airport more than 2 hours early, checked in and waited. They announced over the overhead speakers that our flight was delayed due to mechanical issues. Then delayed again. Then cancelled. We were on the phone with both the airline and priceline ASAP. By "on the phone" I mean "holding for the next available representative...", which was more than an hour wait for both. The airline didn't have another flight they could fit us on until next week. We asked priceline to get us on the next available flight. We held, were disconnected, held, held more, disconnected, held more...until the day was gone. That evening they finally said they booked us on a 6:15 a.m. flight. I asked for an email confirmation and when it didn't arrive several hours later I called back. "Please hold" was the catch phrase of the day. Eventually a rep came on the line and said that we had a 6:15 a.m. flight, gave me the flight number, etc. and said the email would arrive shortly. We went to bed feeling good. We got up at 3 a.m. to get to the airport by 4 a.m. The airline didn't have anything on us. We had two hours to get this straightened out so we weren't TOO worried. "Please hold" When the priceline rep finally came on the phone she said we had reservations and the airline should let us on. Even though it was 5 a.m. now there was a long line at the airport check-in. When we got to the front of the line the guy dug deeper into his system, said he could find our reservation, but that priceline just hadn't purchased the tickets. I told this to the priceline rep on the phone. "Please hold" We watched as our flight left. We spent the day trying to get priceline to get us on a flight, but I was never able to speak to someone able to get us on a flight."

Cons: "You put me on Delta once I got to Detroit. Confusing and exhausting when you're not use to different airports and flying."

Pros: "We arrived on time and safely."
Cons: "The boarding process was a mess. This is due more to the Toronto airport than Air Canada. Passengers standing in front of the entrance to the gate made cueing up to enter when your zone was called impossible. Drinks were offered only twice on the 5 hour flight. Bathrooms were filthy."

Pros: "Nothing"
Cons: "There was NO complementary food for a 5 hour flight. I didn't have a credit card to purchase anything"

Pros: "Efficient process gate to gate. Comfortable seat."
Cons: "Flight attendant ran down the aisle repeating "fasten seatbelts" pretty loudly because we were entering totally mild turbulence. She went seat by seat ensuring that passenger's feet were completely free, i.e. if your purse strap was laying over your toes she made you move it."

Cons: "There was no entertainment system. The boarding was extremely slow and delayed due to the amount of carry on luggage. Ultra slim uncomfortable seats for a 9 hour flight."

Pros: "The flight attendant in Business class was absolutely fantastic. Very friendly, attentive, and fun. She made the trip special."
Cons: "Business were regular seats, but for such a small plane I understand."

Cons: "I retrieved my baggage from the carousel in LAX and it had a wheel torn off! I don't know if it happened NCE to YUL or ;YUL to LAX."

Pros: "Crew's smiles and helpful"
Cons: "Very small seats"

Pros: "The crew was very nice and helpful. The in flight movies are good."
Cons: "Boarding was a little hectic and unorganized. And although my luggage made it to my second flight, my friends luggage was left in Toronto. Now we are in Amsterdam and she has no clothes. My head phone jack was also broken and could barely be used."

Pros: "the whole process was great. staff at the airport and in flight were all friendly and helpful."

Cons: "First leg cancelled after we sat on plane for two hours. Missed connection, arrived 24 hours late. Air Canada provided excellent hotel and meal vouchers, however"

Pros: "Flight was short. Crew was very good"
Cons: "Not much to like in a short hop in a small plane."

Cons: "I was not able to board this flight. And it was such a disappointment and a shocking first for me. I reached the airport and on being checked at the counter, I was told that I cannot board because I don't have a Canadian visa. It was shocking to learn that I needed visa for a 1.5 hour layover. The website should give a prompt or should share the requirements. And all my ticket money got wasted."

Pros: "On board service Comfortable seating and space On time dep. & arrival"
Cons: "None"

Pros: "Friendly crew and quick flight once we got moving"
Cons: "The flight left over an hour late with no real explanation as to why"

Cons: "I asked a crew member to find me a empty space near me so that i don't need to store my luggage in the way way back, and she said she was too short to open and close those overhead bins. SERIOUSLY, HOW DID YOU GET THE DAMN JOB"
