Airline reviews

Pros: "Aircraft was clean and comfortable. Crew was efficient and friendly. The whole experience was excellent!"
Cons: "There was lots of entertainment available but plain old music was not an option. What if I don't want to watch a movie or TV, just listen to music!"

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."

Cons: "Seat cushions are too thin."

Pros: "On time departing and landing."

Cons: "Two rows up from us, I kid threw up all over the center aisle as we were pulling away from the gate. We returned to the gate to allow a cleaning crew to board and clean. However, the cleaning job was rushed and left remnants of the throw up behind which smelled the whole 2.5 hour flight. It really felt unsanitary and unsafe being that it’s unknown what caused the child to get sick. It very well could have been a stomach virus and could have infected the people in rows around the incident due to the mediocre cleaning job. I understand that it’s important to keep flights on-time, especially for connecting flights, but the safety of the passengers and their health should ALWAYS be the #1 priority."

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

Cons: "Employees who just don't care"

Cons: "I missed the flight"

Pros: "Management as well as staff nice...First trip with Alaska and made my trip nice .. Got a good deal price too."

Cons: "Very warm air vents did not work."

Pros: "- Crew was friendly as usual"
Cons: "- The plane was a bit older, so the seats were not as comfortable as most Alaska flights"

Cons: "boarding was late due to repairs on the plane"

Cons: "i wish Alaska would fly straight to Denver from Montana. I fly from Montana to Denver a lot and it ends up being a whole day of travel instead of a couple hour flight."

Pros: "It was on time and friendly"

Pros: "I didn't have to set next to a 500 pound cow."
Cons: "Your beer and wine is sooooooo expensive."

Cons: "Food and wine way over priced."

Pros: "Brand new airplane with comfortable Recaro seats. Great food and wine. Excellent service."
Cons: "Nothing. Alaska Airlines provides the best service available."

Cons: "45 minute delay due to fog"

Pros: "I'm a big fan of Alaska Airlines and their partner Horizon Airlines. I travelled from Edmonton to Denver via Seattle last night. All the staff if pleasant and treats you as a valued customer."

Cons: "No legroom unless you pay more for it."

Pros: "How friendly and professional"

Pros: "On time and effortless."

Pros: "Able to text ..."
Cons: "No Free beer or alternative gluten free snack"

Pros: "Everything"

Pros: "The plane had the usual wifi, drinks and eats. But USB ports and plugs in economy! That's value!"

Pros: "Flight crew was courteous."

Cons: "Gate 11c."

Cons: "Nada"

Cons: "Service was amazing"

Pros: "entertainment"
Cons: "very rough landing, delayed flight with little communication"

Cons: "no chargers"

Pros: "Great service and very organized."

Pros: "price"
Cons: "delayed"

Pros: "Early flight, and short. I think I slept through it. Woke up sore, but eh I'm not surprised by that. I'm a giant and no one woke me up for anything so I was satisfied."

Pros: "The crew and captain were amazing and very apologetic!"
Cons: "I paid an extra $300 for preferred seating because I wanted the extra legroom to sleep. I'm over 6 feet so coach is very uncomfortable. My girlfriend and I got in our seats and 10 minutes later, a crew member walked back and asked us to get off the flight. We got off the flight and were met by police officer. Low and behold, the woman sitting next to us said that she believed we were intoxicated and feared for her safety. I am a police officer and my girlfriend is a nanny/preschool teacher. Not very threatening. The officer on the ground looked us over and asked us a few questions and determined we were not intoxicated and we were no threat to the other passengers. The airline asked us to get back on the flight and we would be sitting in coach because the woman adult children were now sitting in our seats. I told them to book us on another flight with the same seats that I PAID for or put us back in OUR seats on that same flight we just got kicked off of. We were escorted back onto the flight and the crew asked the woman's children to go back to their seats so we could have our seats back. They then asked us not to speak to the woman sitting next to us (which we never did to begin with!!!) and then told us we could have free food and drinks. The whole experience was insanely embarrassed and I can't believe that woman sitting next to us can get away with what she did. I am absolutely livid that they would ask us to get off the flight and then give our seats to the woman's ADULT children without vetting the situation and making the easy determination that we were NOT intoxicated. So embarrassing!!"

Pros: "I was made to feel comfortable right from Bangalore by the checkin people, because I indicated to them that I had a fear of missing my connecting flight from Seattle to Denver. My connection to Denver went smoothly,however the flight attendants on Air Alaska need to be more courteous and friendly."
Cons: "Did not like the flight attendants but the pilot made up for the humour that was lacking. Never seen a pilot interacting the way this one did."

Pros: "Glad I discovered Alaska Airlines!"

Pros: "It got cancelled due to 3 inch of snow. And I missed work in Denver because of it. Very inconvenient"
Cons: "I would like to not have it cancel"

Pros: "Offering price"
Cons: "Real price. Ridiculous after carry-on and other fees"

Pros: "Attendants were very friendly and flight arrived early."
Cons: "We were stuck on the runway for 30 minutes."

Pros: "Newer aircraft"
Cons: "1-1/2 hours delay, no reason was given."

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: "It was great"

Pros: "Ditto statements above"
Cons: "Ditto statements above"

Pros: "Promptness of flight"
Cons: "Cramped seating"

Pros: "good"

Cons: "Nicest people ever."

Cons: "It was great! Nice job Delta !"

Pros: "Christina brown was amazing at gate"

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

Pros: "Nothing"
Cons: "Proper communication"

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: "Love the fact that the head rests move to support your head better."

Cons: "No meal option and my video screen volume did not work"

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

Cons: "No charging outlet."

Pros: "Boarding was easy."
Cons: "I am 6' 1" tall and weigh 220, so not out of the ordinary and I felt like I was stuffed into a sardine can."

Cons: "Better screens for in-flight movies. More legroom or upgrade options."

Pros: "Entertainment"
Cons: "Boarding at JFK.Always messy"

Pros: "Boarding was quick"
Cons: "No entertainment, plane was small"

Pros: "got there on time, no delays. very smooth"

Pros: "Boarding was smooth, attendants were nice and informative, and everything was on time"

Pros: "By"
Cons: "A three hour delay on the first flight and a hour delay on the second..."

Pros: "We boarded close to on time, no hassles. Allowed my husband and me (retired military) to board early, thank you."
Cons: "LAX security is awful. We never left the airport (arrived LAX from Sydney AU) yet were forced thru security again. Had to remove shoes, was scanned and "frisked" by TSA to get to Denver. To go to Australia, Denver TSA waived the removal of shoes, skipped the scan for the metal detector and no one touched me, ditto for LAX on the trip to Sydney. Where's the uniformity or standards for TSA?? Why did I have to be subjected to this garbage on the way home?? This is why I despise flying. It makes no sense to me. This ruined what was a great vacation."

Pros: "Not much. Boarding by "zone" works ok, but is no quicker than most other boarding methods."
Cons: "Boeing 767-400ER seats had no leg room for 6'+ traveller like me. The entertainment system was so old that there were no 115v outlets or USB ports. On a 7-hour flight, that is a significant problem for travellers today with multiple electronic devices. Finally, we were not told in advance that we had to go through security twice and through US Customs BEFORE leaving Dublin. So, the 6-hour layover at JFK was a complete waste of our time as we did not have to go through Customs there."

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

Pros: "Free drinks and snacks - great entertainment system (please read this Frontier)!"
Cons: "Boarding process was agonizingly slow and ineffective"

Cons: "Customs massively backed up. Somewhat disorganized"

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

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

Pros: "The staff really helped me out getting on standby so that I didn't have to wait for a 9 hour layover. Overall great experience and great staff."

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."

Pros: "Great in every way"

Pros: "It got me home, eventually."
Cons: "Poor communication, a 6 hour delay followed by a 7 hour layover (during which we had to sleep on an airport floor because Delta couldn't offer us any hotel vouchers). Gate agents disappeared after 7pm becuase they were due to be done with their shifts when our flight was originally supposed to leave at 6 pm. It felt like we were trapped in the movie The Terminal. Oh! And our bag was misrouted, because that was just how things went those 2 days. All in all a 6 hour trip turned into 18 hours. I could have driven home in that amount of time!"

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

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

Pros: "First leg from San Diego was excellent."

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: "When deplaning in Denver, I was impressed that the captain was the staff who got behind my wheelchair and offered to push me up the walkway :)... New aircraft, kind staff, shorty flight!"
Cons: "Nothing disappointed, butt i didn't have any good besides pretzels."

Cons: "Excellent service excellent pilot"

Cons: "long wait and delayed flight"

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: "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: "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"

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: "IFE was not streaming movies, WiFi on but not loading"

Cons: "Spacing people out until this covid is over"

Pros: "The flight itself was fine."
Cons: "The gate change was not announced on my phone app (changed from E7 to D49). I hate leaving out of Terminal E at MIA. There is no point to having TSA Pre-Check if you have to stand in line with people who don't have it. I have to remove my liquids and laptop. It's such a shabby, run-down terminal."

Pros: "Crew was nice"
Cons: "Not enough leg room. They did a gate change and I almost missed the flight because nothing was announced and when I looked at my phone app it had the previous gate."

Pros: "Nice staff"

Pros: "Friendly staff made people feel safe even during turbulence."

Pros: "The most efficient boarding process I've ever experienced."

Pros: "Ahead of schedule"

Pros: "Movie and tv selection was good. Boarding was a cinch, we took off exactly on time, seats were comfortable, too."

Pros: "Crew"
Cons: "Had to board three times, two different planes. I understand mechanical problems, but 3 hours later, and on another plane, the captain starts making stuff up, saying that the only reason we hadn't moved in the last hour was because people were using the bathroom, then something about having to deplane because the plane couldn't back up with us on it because of some sensor? And then, surprise ! All of the sudden they noticed there was an issue with his and some of the crews' hours and we had to wait till they could locate more crew. But they gave us each a 1/3 glass of water and later a $12 food voucher which didn't even cover a meal and beverage. Whoop-de-do. 7 hours later we finally boarded for the third and last time. The crew on the other hand stayed professional and friendly."

Pros: "Very friendly staff"

Pros: "Perfect"

Cons: "Late flight the crew did.t care and many people missed connections. The customer service at the airport desk was understaffed slow and rude. They we're not helpful in trying to get new flights booked and I felt like it was asking a huge favor even though it was Thier delayed flight that made me miss my connection."

Cons: "I bought my ticket with Air Canadafrom Vancouver to Calgary then connected with Lufthansa from Calgary to London UK. Unknown to me I could not find the flight because it had been changed to an AC reference flight. With a very short time for the connection I did not know where to get my boarding pass as my flight with Lufthansa was nowhere referred to ! Not which gate to go . Why not put it in the ticket that Lufthansa and Air Canada work together and that both flights ref should show !! It would avoid a great deal of anxiety . Only offered 1 round if hot drinks over 9 hours ! Departure delayed by nearly 60 minutes"
