Airline reviews

Pros: "Crew amazing, seat not too comfy"
Cons: "Sits uncomfortable"

Cons: "Flight delay"

Pros: "Great crew."
Cons: "More food choices, but what we had was good."

Pros: "Seats in economy are never comfortable. And someone also reclines their seat. But overall bathrooms were clean and food was good. Really no complaints about the flight itself or the crew!"
Cons: "Carry ons are too big! People should not be allowed to bring a piece of luggage inside the cabin. They are very heavy and some people cannot even lift them to place them in overhead compartment. Makes boarding slower and more complicated. Seats need to be a little wider. If a big person sits next"

Cons: "Too cold"

Cons: "No air conditioning in the plane and we had to sit on the runway for 25-30 minutes, very uncomfortable and we weren’t kept up on what was going on. Crew acted like they didn’t want to be there"

Pros: "They didn’t want to help"

Pros: "Nothing exceptional stands out"
Cons: "Flight was not on time"

Cons: "Flight was delayed and completely packed so our family could not get seats together"

Pros: "The crew was really nice! They were very energetic!"
Cons: "I am not blaming the airline, but the Salt Lake Airport. Everything was slow and everything was delayed! The airport staff was friendly, but airport management needs be prepared and perform better. Compared to other airport, there was not that many people flying, and still there processing issues."

Pros: "The seats were very comfortable even though legroom was limited in the basic cabin."

Pros: "I like how friendly the crew was"
Cons: "Our flight was delayed by an hour and we had a connecting flight IN ATL that we had to get to in :30 minutes. By the time we got off the plane we had :15 minutes to get to our connecting flight. We barely made it. They were about to close the door on us. Didnt really appreciate that."

Pros: "see above"

Pros: "This was my daughter’s first solo travel home from college. She said the staff was helpful and kind. She loved that the flight was not over crowded. It was a smooth flight."
Cons: "Only negative thing she could say was her flight was delayed an hour. But that isn’t terrible considering all the holiday travelers."

Pros: "The service and the crew were extremely courteous polite and professional ."
Cons: "As it is an all flights just not enough leg room and a very tight chair."

Pros: "entertainment and leg room on regular seats"
Cons: "delay, boarding process"

Cons: "It was a 1.5 hour late leaving San Diego (6am flight), one of three bathrooms out, no coffee or tea (wtf?), we circled Atlanta for an hour, ran out of gas, landed in Pensacola, no information, missed the flight to DC ... And it's not even noon"

Pros: "Female flight attendant was incredibly personable and had a bubbly personality. Definitely made you want to smile"

Cons: "Flight delayed 2 hrs"

Pros: "After almost every airline cancelled. Delta still took me to where I needed to go with not one single problem. That pilot was amazing. I forget his name. But the plane didn't slide or anything during take off. Amazing."
Cons: "What was there not to like. We were a little bit late but I wasn't in a rush. I planned well ahead. Delta moved my flight from 10 a.m. to 6 a.m. and that was perfectly fine with me."

Cons: "Not enough room. Could have better technology and better food choices."

Cons: "It takes time and worries to find the air train and Aeroflot registration."

Cons: "Sandwich for dinner"

Pros: "Short and nice flight"

Pros: "Was initially hoping to fly a US airline but will now look for Aeromexico first. Exceeded my expectations!"
Cons: "The layover in Mexico City was a bit long and the airport was not so great"

Pros: "Boarding was quick. Staff and crew were friendly. Everything went well despite the 30 min delay we had on the runway. They gave us snacks and we ended up still arriving on time."

Pros: "Even though one couldn't hear an announcement Delta did have a staff person tell people where to line up for different zones. Flight was fine and on time."
Cons: "Couldn't clearly hear any announcements and once it was getting closer to boarding time as usual so many people just start gathering in a mass. (It would be so much easier to have signs label Zone 1 ,2, etc.)"

Pros: "The stewards and flight was overall fine. In fact I found the stewards to Atlanta from West Palm very accommodating."
Cons: "I have reservation on booking Comfort plus next time I fly though. There appeared to be no difference in the seating or service as economy. A lesson learn I guess. I will atillflyDelta but stick to economy. I saw no perks"

Pros: "Boarding, checking in etc. The usual stuff, nothign spectacular."
Cons: "Seats are getting too crowded!"

Pros: "The boarding process in Atlanta was as smooth as could be expected given that it was a full flight. I appreciated the gate announcer's suggestions to everyone about how to ease the overhead baggage crunch."
Cons: "Economy is very tight quarters."

Pros: "The crew was beyond friendly and courteous. Lots of leg room."
Cons: "I was an older plane, it was louder than our flight down to Atlanta. Nothing they could do about it, but a slight annoyance."

Pros: "Flight wasn't full so the service was very good lots of food and snacks and we arrived early too"
Cons: "Music was a. Bit limited"

Pros: "I was going for weekend trip and because of delays I would've been there less than 20 hours. But Delta was terrific in giving me a refund and essy to work with via Twitter. 2 hour phone delay but they called me back to complete refund."
Cons: "Chaos at gates. Changed gate 3 times. No real updates."

Pros: "There is nothing I like the most. Everything was downside from the day one immediately the purchase of the tickets."
Cons: "With the purchase of tickets there was no meal selection option available. Had to ask at the reporting time and then seat was messed up. 3 seats were three different row while I had two minor sons. Spoke to the travel agents (justfly.com) and requested meal was not properly recorded. I requested, two kids meal and a Hindu meal, when meal came it was told I had Muslim meal. How on earth did it make any sense, I am not even muslim? I did not even mention about muslim. Those dumbass at justfly.com do not have any level of professionalism. I tried to contact china southern airlines, they are always busy, after several attempts, finally somebody on the phone talking chinese shitty accents that only understood a few english. Chinese passenger crowded and with the shitty attitudes. One of the old guy drop the heavy coffee cup on my son's head and hurt real bad when he pulled his bag immediately after the land when he is not supposed to. I have a return ticket to deal with again with pain in a few days. then I will never fly with this shitty airlines. At Gongzhau, kids are hungry in transit, tried to buy food, told they only take Yuan. there was no ATM in transit. had to exchange Yuan and thats the only option there if you want to buy something. Airport wi-fi sucks, no connectivity even after logging into the shitty local advertisers websites. Finally, crew were to manage some kind of food, but did not like it at all. shitty shitty. do no fly this airlines of chinese route at all."

Pros: "Friendly and informative flight attendants kept the passengers in reasonable spirit."
Cons: "Left nearly an hour late after confusion related to oversold seats and upgrades. The gate agent entered the plane multiple times. The landing was rough, the brakes were loud."

Pros: "They were courteous and prepared, when they couldn't offer something they gave me options for other things, and seemed genuinely concerned about my experience!"
Cons: "i don't have any real complaints. Economy seating is still economy seating, so those problems didn't go away"

Cons: "Most everything was excellent, however my 2 year old daughter's in seat entertainment screen wasn't working. It was a full flight and there was no option to change seats. I brought it to the flight attendants attention however she wasn't able to reset it. A 7-hour flight from NY to Zurich travelling with small children without the movies was not as pleasant as it could have been."

Cons: "It was late arriving to greensboro"

Cons: "No fruit and cheese available to purchase one the flight. Need more than cookies"

Pros: "Meal quality has improved"

Cons: "It enough leg room and I am not tall. I'm 5'5""

Pros: "The crew was friendly and accommodating, and service was good"
Cons: "I purchased a basic economy ticket and upon checking in, my Delta app said my seat was unassigned and I had to get my boarding pass at the airport. I checked back later and the app had me as number 7 on the standby list. I called Delta (wait time 3+ hours... my flight was in 3), and then the Delta app support where I was able to get through to someone. She told me that the ticket I purchased over a month in advance did not guarantee me a seat on the plane (???). She said that if I was bumped from the flight they would reschedule me for the next morning. She was pretty rude and made it seem like I had a 50/50 shot of getting on this plane. I rushed to the airport in hopes that I would be the first from Standby there, and the gate agent told me that I was fine and would board right after first class and be assigned a seat then. Great. Once I got my seat assignment, I board to find out there is someone else sitting in my seat...... They eventually called the desk and had her moved, but it was the weirdest boarding experience I've had.. and I've flown Spirit. These planes that Delta fly's are SO OLD. Both times I have flown Delta the "turbulence" has been so bad and cold air was blowing right on my the whole flight with no option to turn it off (it wasn't from one of the vents, but from the side). Someone close to me works for Delta and I know for a fact that some of their engines blow mid-flight.. and they tell the passengers that it's turbulence.. so that doesn't make me feel very safe. I won't fly Delta again if there is another comparable option."

Cons: "I understand delays happen, but Delta delayed the flight significantly and only informed customers around the time they had arrived at the airport - especially for an early morning flight, where you are counting on being able to sleep on the plane ASAP, that is absolute hell. If they had messaged even 30 mins earlier, we could have rescheduled our cab and slept at the hotel given we were on 2 hours sleep. We received the text 3 minutes before we arrived at the airport and tried to sleep on benches as the front desk kept delaying the boarding time by 20 minutes 4 times, each time exactly at the previously extended ETD, which is far more frustrating than if they had just extended it once by 80 minutes so we could legitimately relax."

Pros: "Boarding and deplaning were efficient. Crew was good. Seats were comfortable."
Cons: "Seat was near the restroom and there was an odor for the second half of the flight. Issues with the A/V - hum in the headphones and the touch screen only worked intermittently. Cabin temperature was a bit cold."

Cons: "Flight attendants were a little snobby and didn't treat all passengers equally, in my humble opinion (note: I was sitting in 1st class)."

Pros: "Very informative staff"
Cons: "Was late"

Cons: "Told to drop down a class on arrival at gate."

Pros: "Was kept aware of all the delay times and when, how to rebook flights for missed connections."
Cons: "Two hour delay taking off"

Pros: "Always have great experience with Delta flight attendants and staff. The entertainment on mobile phone was a really nice add-on, I had never seen before."
Cons: "Flight was delayed in taking off, waiting for connecting passengers. Plane was old, which is most Delta planes, but this one showed it. The tray table looked like it was from the 70s or 80s. Flying into Midway instead of O'hare was anticlimactic."

Cons: "Luggage costs"

Cons: "I find the planes are far to compact and its really hard if you have a long flight. The body becomes stiff and really sore from not being able to move about much."

Pros: "Crew was friendly"
Cons: "Tv"

Cons: "Can't rate this because I missed my connecting flight from LAX to SJC due to a Westjet mechanical issue."

Pros: "Didn't see much of crew. Food was crazy expensive for what it was."
Cons: "Better food for price, or an option to pre-book a proper meal at time of buying ticket. Plane was cold and no blankets."

Pros: "Crew was great! Seat space was a bit tight"
Cons: "Little more space and leg room"

Cons: "No explanation was given why flight left almost 2 hours late"

Pros: "Crew was great. I was able to watch my favourite CBC shows due to the screen on the seat in front."
Cons: "Nothing really, I paid $500 for the return flight and feel I got fair value for the cost."

Pros: "Amazing crew. Brand new plane."

Cons: "Both flights delayed"

Pros: "The crew was polite and prot"
Cons: "It wasn’t free"

Pros: "The pilots made the trip in great time. The landing was good."
Cons: "We were told we could board the flight, then when we got to the steps in the cold and dark we were sent back.The staff were not very friendly with the customers somewhat superficial, but with each other it was like they were at a party. Not impressed by the 2 young women."

Pros: "Consistencies on bagage claim info, and changes in boarding gates."
Cons: "Inconsistencies, on my way back to montreal from the philippines, i was informed that baggage would be claimed directly to final port of destination but didnt, when i arrived at toronto i had to take my bagage and drop it off again, although my next flight would be with west jet airlines, korean air was not able to communicate well with their airline partners as to bagage claim and changes in boarding gates."

Pros: "The movies"
Cons: "So far so good"

Pros: "Flight was on time and WJ does provide quite a lot of leg room on their jets."

Pros: "The ease of boarding with very nice staff!"

Pros: "Friendly crew"
Cons: "No entertainment and bag charge."

Pros: "I got to watch "The Post", which took the entire time of the flight. I've wanted to see that movie for months and didn't know how that would happen! Easy flight, good service, friendly crew."

Pros: "Airport staff went above and beyond to get my mother through the airport. We had a tight transfer and they helped us make it to the gate on time."
Cons: "There was no time to eat. Nothing other than snacks. The time allotted was *barely* sufficient to get from gate to gate. We were starving when we got to our destination."

Pros: "The flight was on time."

Pros: "Flight was on time and flight crew was very friendly."
Cons: "Having to exit the terminal and go through security again when changing planes in Toronto."

Cons: "Economy too cramped."

Pros: "Staff was friendly and very helpful."
Cons: "We had a little extra lay over due to the snow, not there problem."

Pros: "I’m very good"

Pros: "Everything went smoothly. Flight on time."

Pros: "Great staff and spacious plane"
Cons: "Long"

Cons: "It took several hours for the decision to be made to cancel our original flight from PV to Van, and when the final decision was made, the complete lack of sympathy or communication came as a shock. No one informed us why we were moving to another terminal or that our flight had actually been cancelled and we would be staying another night in Mexico for another two hours. Getting our hotel voucher and transportation to the venue took another several hours. (Sorry Westin, but you also receive poor marks on your food services. Your front desk people were great though!) The following morning we were not informed that there would be no food service on the flight, so my kids were starving by the time we touched down in Vancouver. The ordeal was exhausting and when we finally arrived in Vancouver we almost missed our connecting flight because of a huge error in off-loading our luggage. It shouldn’t take over an hour to receive your luggage. Again, the communications break down led to hightened anxiety and stress. The whole horrible journey home with WestJet made the loveliness of my actual holiday pale into the background. I was very disappointed in WestJet as I’ve had fabulous experiences in the past. If possible, I will avoid flying with them again any time soon."

Cons: "First leg of flight was cancelled. Plane didn't come in at midnight as scheduled, so was not available for departure at 6:20 AM. WestJet did not inform anyone - including Kayak. Apps westjet & kayak said departure was on time, but there was no plane."

Pros: "everything"
Cons: "nothing"

Pros: "That we could sleep during the flight. The attendants left us alone when we were sleeping."

Pros: "The wifi inflight service"
Cons: "No food, only snacks."

Pros: "Very disciplined and hard-working crew did their best to keep everything under control and moving on schedule. Boarding was busy but fairly well organized considering."
Cons: "Flight had an abundance of minors and babies at no fault of anyone, just unfortunate. Lots of crying, screaming, fidgeting and puking. Customers were pretty impatient in the early morning as well which didn't help the situation. Not sure if snacks or refreshments (other than water) we're handed out in a 4.5 hour flight as well."

Pros: "Cancelled the flight and was utter chaos with no direction what so ever."
Cons: "Staff would not communicate with the passenger's."

Pros: "The crew tried their best. The seats were average. The food ok."
Cons: "The entertainment is awful to non-existent. The wifi doesn't work especially on a laptop. On the return flight is wasn't even enabled. Four to five hours without ANY entertainment is totally unacceptable especially with teens and kids!! The 20 schedule changes and very confusing schedule (they showed us on 2 separate flights from DTW on Dec 25th morning). I have no idea how that would happen. The gate agent at Delta (first leg) had a hell of a time sorting it out despite a long call to the WJ help desk."

Cons: "Plane was delayed by 3 hours."

Cons: "The overhead bins are now too small for a large number of carry on luggage that meets the criteria of carry on. If you wheel your now over sized carry on to the gate they will stow it below for free. If you check it they charge you $26.00 knowing it won't fit in the bins anyway."

Pros: "Friendly crew, easy boarding! Small overhead but crew took larger bags under the plane for no charge."

Pros: "It was on time. Quick to board."
Cons: "I’m used to entertainment."

Pros: "Planes were clean and crew was polite. Plenty of leg room."
Cons: "I was not able to check online. Their kiosks at the airport were out of order. All of them! All their baggages were being photographed and double tagged. They had to call some where to get me a boarding pass. It seemed like they were doing their best to discourage me, never to fly with WestJet. And they might have just succeeded."

Pros: "Great leg room, flight was on time. Flight attendants were super nice and accommodating."

Pros: "It was a good flight. Comfortable and on time."
Cons: "I rated food low as there wasn't any nor did I expect it. No problem."

Pros: "Crew were all very welcoming and polite"
Cons: "Food and entertainment were pretty pricey."

Cons: "Because the flight left late, 3 of us had to RUN through the Toronto airport from one end to the other, in order to barely catch our connecting flight from Toronto to Ottawa."

Cons: "They automatically gave me the window seat"

Pros: "Bell's live TV is probably the best feature!"

Pros: "Everything was shipshape and organized. Every crew membe r we talked with seemed knowledgeable and friendly. Good value."

Pros: "Low cost, supportive seating"
Cons: "Meals are extra Arrived a bit early and had to wait about 15 min for someone to attach the gate"

Pros: "Great service! Crew was very friendly and happy. Flight was online and landed early"

Pros: "Poor"
Cons: "Luggage did not arrive in Pisa. No big concern expressed or info given in support of what I could spend to get essentials. Poor communication. Need an English speaking BA employee to sort these messes out. My luggage was to go from Londod ON Canada to Toronto Canada to Heathrow UK to Pisa. Made call in evening and part of info I had given at airport as to my hotels to receive luggage when found was not communicated in the computer.Luckily I called."

Cons: "we didnt have an eta number to check in our flight on time. The front desk staff iwas so nice and helpful to rebook a later flight for us without having us to pay extra."

Cons: "Connections to US destinations now require your checked in baggage to be processed before you can proceed to your connecting flights. The real problem is that this is no sign or communications describing this. Everyone is simply stopped in the corridor and told that they cannot proceed farther until their name comes up green on a monitor. Unfortunately the monitor switches displays so frequently that it is almost impossible to read. In addition to that it seems names do not always appear on the monitor unless you get your boarding pass scanned a the desk (this is not communicated to you unless you ask why your name is not on the monitor at all). People late for connecting flights (because of inbound flight delays) are required to wait without explanation sometimes needlessly if they don't have a checked bag. A nightmare if you're trying to make your connection. In addition once you've cleared that hurdle you need to go through security again (something we were unprepared for since we were already in the secure area. You then proceed to customs and then your connecting flight (if you haven't already missed it by then). Allow lots of time to get to your connecting flight, and ask to get you boarding pass scanned at that mysterious "checked bag" stop in the corridor."

Pros: "general state and size and comfort of the plane. Overall AC experience always good. The flight back to montreal, the service was exceptional!"
Cons: "only a dairy plate available, next time I need to specify no dairy entertainment -- too many ads and no previews for the movies so I have to start playing then stop and go through the entire same series of ads for the next one. the system just seems clunky and antiquated in today's tech age."

Cons: "Late flight No communication Had done pre register to sit with father. They changed his seat upon boarding."

Pros: "Everything was perfect"

Pros: "The crew was very friendly and attentive."

Pros: "The staff rocked it, despite being in a tough position with grumpy passengers. The desk staff before boarding was less helpful. The seats were comfortable. Entertainment was rated low because it was a short flight it really should have been an N/A because I didn't use it. Not sure how to fairly rate that. No food as far as I could tell."
Cons: "2 hour delay, then sat for another hour or so after being the last to board for fueling and waiting for ground crew."

Pros: "The flight last less time than expected."

Pros: "Flight was good but there was no tv"
Cons: "There was no TV or to play games"

Cons: "The fact that my ticket said something different from my itinerary and I spent far too long at the counter to get a seat assignment."

Cons: "We were late getting into Chicago and I missed my connection to Albuquerque. I was scheduled to arrive at my destination at noon and because we were late, I didn't get home until almost midnight."

Pros: "Seats had a decent amount of room."
Cons: "Aircanada'swe boarding system is again and everyone in later zones just blocks everyone else. Due to issues mentioned on the flight above my husband didn't get his luggage. We are still waiting."

Pros: "entertainment choices"
Cons: "boarding process crew not helpful in baggage storage"

Pros: "Legroom of seat, on demand and complimentary entertainment system and stable connection of Wifi."
Cons: "Delay of the flight..."

Pros: "One person assisting passengers whose flights had been canceled was gracious and skillful."
Cons: "My flight, 370 was canceled. Initially, one of the AC staff at customer service was overwhelmed and impatient. The next flight was delayed by about seven hours. My baggage didn't arrive in Toronto. I found it extremely difficult to learn where the baggage could be, spent hours on hold with Air Canada and then Dynamex, and waited four days to receive my bag. I was with about 100 people at a summer camp. The staff created a funny skit about AC, Dynamex (sp?) and the endless "your call is important to us" tape recording. I understand that flight plans must be canceled and changed due to weather, but AC relies too heavily on automated "service.""

Pros: "Was arbitrarily assigned a seat with extra legroom. No excessive turbulence; landing was smooth."
Cons: "I was among the last to board and had to place my carry-on under the seat in front because there was no room in the overhead bin. This kept me cramped the entire time despite the "preferred" seating. Soft drink servings were really skimpy."

Pros: "Quick flight, on time."
Cons: "The TV's in the back of the seats didn't turn on for this short flight."

Pros: "More leg room and in flight entertainment."
Cons: "Stewardess spilled hot tea on my husband and did not apologize."

Pros: "Nice plane, decent seats."
Cons: "Delayed flight. Luggage didn't make it on to the aircraft in Toronto. Only 4 agents working the counters with a line of about 80+ or so people trying to check in with no supervisor present to make things better or get more counters open. Security didn't stamp boarding pass so had to go back to security check point to get boarding pass stamped before boarding. And it is no longer "random selection" when you get "randomly" selected for extra screening every time you travel from Toronto!!!"

Cons: "Flight delayed, service with discrimination, pride, specially male crew, this is a really bad flight experience."

Cons: "It was so late, I almost missed my connecting flight. They were not helpful. They did not communicate well and they refused to take any responsibility."

Cons: "Very bad cabin pressure -- lots of ear pain."

Pros: "Again, nice selection of entertainment and great crew."

Cons: "There was some dripping from the ceiling on those of us in the back of the plane. It might have been condensation from the air conditioning or air flow nozzles. In the groove of the ceiling immediately over the seats there seemed to be some dirt or mold."

Pros: "Not much can go wrong on a flight shorter than 90 minutes."
Cons: "3 delays that added up to 1 hr, but counter personnel kept us informed."

Pros: "I sat with my husband by the window."
Cons: "First the plane had a delay for an hour, then additional two more hours of delay because we had to wait for another plane with passengers had to connect to the flight. Once we were boarded, we waited another hour for more passengers with luggage issues. After the plane took off, I was happy that the crews continued to offer us water, then I found out that there was no meal plan for the flight. I was hungry after all the unexpected wait plus the 4.5 hours flight to Chicago. I feel that the airline could offer passengers a meal after all the unexpected delays."

Pros: "You want comfort? this is the way to go."
Cons: "Entertainment on short flight was limited."

Pros: "I . was impressed with the food and service.over all the whole trip was very good"
Cons: "there was nothing I did not like"

Cons: "Moving through security and customs in the Toronto airport was incredibly slow, with 4 or 5 checkpoints, all with lines. Staff were polite but there were not enough of them. We almost missed our connecting flight, and our bags apparently did miss it, because they have not yet arrived in Chicago (see previous comments). Air Canada should have seen the problem in terms of timing with the connecting flight and expedited better. Will try to avoid Air Canada in the future, especially if there are connections in Toronto."

Pros: "All went smoothly"

Cons: "if you get in a que, then the computer goes down , your dead, AC line will be 1.5 hours to get to rebook. then you have 2 day to stay before you can get out. if you decide to go on delta because staying 2 day in hotel is more expensive than buying a new ticket ac will not refund you. Air Canada is the least flexible airline in the world relative to refund."

Pros: "The crew members in both the flights were amazing. they seemed like they enjoyed their job. Its not very common at Air Canada."
Cons: "The flight from Chicago to Toronto was delayed by half hour. But the boarding gate agents did not even mention the delay."

Cons: "after wetting half hour in the line they said i didn't pay for my ticket and tell me to parches a new ticket"

Pros: "It was comfy. Individual screen."
Cons: "We took off 25 minutes late and no food was served, not even a snack. I had to pay 25$ to check in my suitcase."

Cons: "Team in Chicago at Baggage Services was not helpful."

Cons: "Flight was late"

Pros: "Run by united but more efficient than a recent Air Canada flight."
Cons: "3 hour flight and had to pay extra for entertainment. Only two biscuits given for food. Cramped seats for anyone 6ft tall."

Cons: "I could not check in online for both legs of the flight. Stuck in the middle seat even though I was ready to check in 24 hrs prior."

Pros: "the short flight"
Cons: "the comfort and location of seats ran around for days acquiring a doctors note for easy access seating. grateful for the refund but would've rather paid and actually been accommodated."

Pros: "Overall it was good. The crew was very friendly. The plane was small and it was a short flight, so everything else was average as expected for a short flight."

Pros: "The crew was good and the in-flight entertainment options were decent."
Cons: "Plane took forever to take off because we were waiting for people late from layovers. Got one drink, no snacks, nothing else. Plane arrived over an hour late."

Cons: "It was a United flight and everywhere it said it was Air Canada instead of United. Hopping terminals and running through them last minute is not fun. To top it off the flight got delayed a ton of times and messed up our schedules completely."

Pros: "Everithing-----Ramesh"
Cons: "Ramesh"

Pros: "Crew are very friendly and boarding was a breeze."
Cons: "For the huge amount of money they charge us for national flight with no included meals or even snacks its ridiculous!!"

Cons: "delayed 2-3 hours in Vancouver so missed connection, had to rent a vehicle to get home. Everytime, United into O'Hare… never again!"

Pros: "Cancellation came with a new flight and coucher for sleeping overnight at a O'Hare Hotel which was very well organized and went smoothly. Staff at ORD were waiting for us and very helpful."
Cons: "Was unable to check in my Air Canada flight the day before to find out the next day, at the airport that the flight was cancelled. The Air Canada flight was operated by United and no such information was provided in my reservation on Kayak or at the Air Canada counter in SAN airport, so I had to guess that another Star Alliance member would be taking over."

Pros: "Mechanical..missed connection in Toronto"

Pros: "Great first experience flying."

Pros: "Still able to make it there on the day I needed to be there"
Cons: "Had to be rerouted"
