Pros: "Nothing, the flight was canceled without a refund. I highly recommend canceling all business with kiwi in the future."
Cons: "My flight could have occurred or I could have been refunded."

Pros: "Being on time with everything."
Cons: "Nothing"

Cons: "Really felt happy on time touch down nice journey with delta"

Cons: "even though I was in Delta One -- the seats in the reclined position were kind of narrow, arm rests in the way made it difficult to turn over, IF I were trying to sleep. but i loved being in first class -- the only way to go on a long flight :)"

Pros: "Everything was good starting with boarding to disembarking airplane. Crew was respectful and the airplane seemed to be clean in general. I’m flight entertainment is excellent and made the flight seem a lot shorter."
Cons: "Boarding pass has specific alphabet zones but boarding was done via cabin number which was slightly confusing. I didn’t realize that zone E is part of cabin 2. I think more clear instructions should be given."

Pros: "Friendly crew"

Cons: "My wife and I couldn't sit together regarless of how much money we wished to spend on reserving seats."

Pros: "The crew was amazing! The seat was comfortable."
Cons: "Used the self check in kiosk to begin! That was awesome! But after that I still had to stand in line to check in my bags. That part of the process took a bit longer than expected."

Pros: "Nothing special"
Cons: "That was the most uncomfortable and cramped seat I had ever had on a plane flight. Even sitting on the pillow did not help."

Cons: "Delta comfort works especially for one who is handicapped"

Pros: "I like that I arrived at my destination safely."
Cons: "My allergies were bothering me due to the airlines allowing animals to travel as passengers, in this case a rabbit. I am very allergic to animals. My breathing was compromised."

Pros: "This had one of the best attendants I have encountered. She was extra friendly and made us feel good."

Cons: "My flight from Chicago was two hours late and that's why I missed the flight from Atlanta to Buenos Aires. No one helped and did not know that the flight was delayed and I had to find a place to sleep. I'm not satisfied with the experience and I have not yet arrived in Argentina because of the whole"

Cons: "The flight was 2 hours delayed.. this cause a lot of inconvienece.."

Cons: "... on top of that I kindly requested to speak with a supervisor and i was denied it. As a customer I deserved that. I would a ticket with Aerolineas and nowhere it said it was delta. I followed the baggage allowance explained on kayak website and on Aerolineas Argentinas. I took a bicycle which is free and i pay $100 to packed it as Aerolineas wanted. When I arrived it was a Delta flight and they told they don't allow bicycles and that i had to play $150. Aerolineas website and kayak clearly says that bicycles were free on my flight. I show the agent my ticket and that no where it said delta to consider what he was saying since it is an alliance but i was not informed about it. He said no and after wait there for a while before boarding i kindly ask to speak with a supervisor and the denied it and disappeared. I request a refund of my fee to you for providing incorrect information."

Cons: "The flight attendants were unfriendly, condescending. They seemed unhappy about having to serve people."

Pros: "Everything was on time and efficient. I also liked that the captain came on and updated us on arrival, turbulence, weather, etc."

Pros: "Professional appearance of flight staff accommodating and sincete"

Pros: "Take off on time, arrived early, pleasant flight attendant"
Cons: "Had to sit on tarmac after arriving early"

Cons: "Flight was delayed out of St. Louis causing several of us to miss our connecting flight from Salt Lake City to Portland. Delta was of very little help in assisting us in making a connecting flight. They could have at least helped with travel arrangements and provided us with a little food, a pillow and a blanket as we waited in their terminal for the next flight on their airline which was a several hour wait. I understand these things happen but the passengers didn't cause the problem and Delta needs to take care of people better if they expect to earn repeat business."

Pros: "I do not fly and took my first flight in eight years on aDelta flight. They are partners with KLM. We were late leaving SFO due to traffic..no fault of there’s. I just missed my connecting flight and they have booked me to leave a day later. I was also given a room at Marriott. I appreciate their service and the entire crew from check in to landing. I am now a fan of Delta as well as KLM."

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: "Seat was narrow from side to side; so short from front to back that only half my thigh was supported; hard; and pitched slightly forward from uneven wear. This was an exit row, so I had legroom at least. I’m 5’4” and trim. A taller, or broader person would not fit!"

Cons: "Ac not working at last 30 minutes of flight."

Pros: "Nothing"
Cons: "We lost our whole vacation and had to pay for the plans fare twice because My last name was spelled wrong on our tickets and we were unable to use them because my passport didn’t match the name on the ticket. We had to rebook everything pay almost twice as much for the plane fare, our Lodi g cost more and our trip was delayed for two weeks. Vyama is blaming us for spelling our name wrong and claimes that it’s our fault this happened because everything is automated. There saying they don’t touch anything that we enter into the booking but somehow everything they claim we entered is now in all capital letters and the space between our first name and middle name is now gone and all run together. The coustomer service number gets you to someone in India. I have tried to get this addressed four times now at first they tried to place the responsibility on the airlines now us and they have hung up on me twice. Kayak has been worthless, they also just pass the responsibility on to someone else. We will never use them again ant I intend to make sure that this mess is put out in social media to hopefully keep others from having their travel plans ruined by their flawed system."

Cons: "They changed my flight to a different one departing 2 hours earlier and did not notify me! The original flight was still available & they would not let me take it despite my reservation paper work. CRAZY! I have a two hour drive to the airport this gave me the option to leave home at 2:30am or go the night before and pay for a hotel. Flight was managed by DELTA who also did not care! All involved blamed each other. Beware"

Pros: "Entertainment"
Cons: "The crew was extremely rude. I was skipped got beverages twice and when I rang the bell the flight attendant gave me a lot of attitude. No one likes to fly for 10 hours, I get it, but it was extremely unprofessional."

Pros: "In flight movies"
Cons: "The flight was 3 hours late taking off which made us miss our connection to chicago so we are stuck in Atlanta tonight with unplanned expenses we were not planning on!"

Cons: "Flight was delayed ... wish I had received text notice instead of email so I could have enjoyed the extra hours of vacation instead of sitting at airport."

Pros: "Very friendly crew"
Cons: "Seatbelts very short given ample seat size"

Pros: "Friendly staff staff, smooth boarding experience, DC+ positive experience"
Cons: "757-200 outdated for having spent 10 hours on that same plane (stop but no plane change) having flown shorter haul flights on many updated 757 was disappointing."

Pros: "Everything from the check-in to the landing was great. We were well informed about what was going on with out luggage (we were on a regional flight) and the assortment of free snacks were superb! I guess I'll be a returning customer"
Cons: "I was expecting some form of entertainment (radio, overhead monitor, etc) on the CRJ700. But it really don't take away from the experience since T-Mobile partnered with the Wi-Fi service and I received a free hour of Wi-Fi!"

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!!!!"

Cons: "My flight got to New York so late!!!! I missed my international flight."

Cons: "Not great communication from gate or staff on board. Failed to provide adequate water. No ice on super warm flight. Just bad experience overall."

Cons: "Nothing was bad."

Pros: "Crew was great."
Cons: "Plane was terrible. Not paying Delta prices to fly in a Spirit plane"

Cons: "turbulance"

Pros: "I was cleared for standby! Flight attendant at the stl gate is always friendly and willing to help! I love her!"
Cons: "I waited almost 6 hours on the phone the night before the flight to get on standby! Almost didn't get the flight! Was charged $50 only to not get on my next flight because it was over booked! Flight attendant was very rude!"

Pros: "I liked that I was able to get able to get an earlier flight!"
Cons: "I don't like that I had to pay $50 extra dollars for standby on both legs of my flight! I am a very loyal delta customer and these past times flying I feel like my favorite airline is turning into the bad airlines delay everytime, problems with the plane fare prices too high! I'm starting to think about taking my business elsewhere!"

Pros: "The boarding process was very efficient and the staff was both very sympathetic as well as helping. I had great flights with you, thanks!"
Cons: "The food has few to none vegetarian/vegan options. These days more and more people are trying to eat in a less cruel and healthier way. It would be great if you could keep up with that trend =) Otherwise it would really make me (and a lot of other people) happy if the disposable items such as cutlery and packaging were optional, so to reduce the plastic waste. All in all you offer a great service =)"

Pros: "I loved the fact that you let people fly with pets in the cabin, it's such a leap forward for us animal lovers! Even if it was not my pet I really appreciete that you enable people to travel with their pets =)"
Cons: "The food has few to none vegetarian/vegan options. These days more and more people are trying to eat in a less cruel and healthier way. It would be great if you could keep up with that trend =) Otherwise it would really make me (and a lot of other people) happy if the disposable items such as cutlery and packaging were optional, so to reduce the plastic waste.

Cons: "Crew wasn't good"

Pros: "Nothing since my negative stressed the whole trip."
Cons: "We have long names, 4. It was correct in the booking with Layak but copa charged us $120 US / 2,090 MXP For correcting. Saying that Kayak didn't transmit everything. It was pay or be denied boarding."

Pros: "When they booked me on another airline after making me wait 36 hours and finally admitting it was their mistake they inadvertently cancelled my reservation."
Cons: "They intolerant, unprofessional, they overbook flights and blame the passenger, they don't help you when this happens, they cancelled my booking and tried to blame me, they act as if they have a right to treat a customer like garbage. Don't EVER book a flight with this company. If you do you are taking a huge risk."

Cons: "Everyone everything"

Pros: "Short flight Good space inflight"
Cons: "Awful boarding, kept standing until everyone else was in the plane even though I was second in line, very inefficient crew. Only a few movies to watch"

Pros: "Boarding was very easy and fast"

Cons: "I flight from Panamá to bs as at least 10 times a year, and I have Presidential Platinum status, never in all the flights I receive my luggage with priority. It doesn't matter if the have the priority sign, no one respect that. Panama airport use to be a good airport, now you can't really buy anything because they don't accept credit cards, and the Copa saloon is always full, so I'm thinking on flying avianca from now on."

Cons: "No matter if you have priority in your bags, in Buenos Aires is always the same, the bags come last."

Cons: "I was 5 minutes late checking in for my flight from LAX to Cali. Another airlines was 7 hours late delivering me to LAX. My situation dictated that I arrive in to Cali at a specific time. I couldn't wait for 24 hours for the next flight. So I booked a new flight to get me to Cali on time. Here's the problem.. when I went to check for the Cali to LAX flight the gate agent informed me that because I failed to check in for the flight to Cali. That that cancels the entire ticket. I was forced to purchase an entire new ticket to fly back to LAX"

Pros: "Great customer service, great flight attendants, great everything!!!! Most of all no terbulance"
Cons: "I wish I would of sat next to my wife."

Pros: "The service and the crew were really friendly and my experience in general was great would recommend hands down, can't go wrong with Copa airlines"
Cons: "Food can be improved a little, but in general I would say is good, so no complaints just a suggestion overall great experience."

Cons: "I was unable to travel with three suitcases, despite the fact that I was willing to pay for the third bag. I had to put some of my stuff in another bag and was charged overweight. What infuriates me is the fact that at no point of the web check in process I was warned about this. No warning, no email, nothing. I am never using Copa Airlines again and I am warning everyone I know not to use this third-rate airline ever!"

Pros: "Plane was new"
Cons: "Extremely cramped, surly flight attendants, and terrible food."

Pros: "You got us there safely."
Cons: "Not sure who is at fault for running out of de-ice solution, but keeping us sitting on the tarmac without air ventilation for almost 3 hours... with only an apology and a last minute glass of water? that was terrible customer service."

Pros: "Flight did not take place because of cancelled return flight. the whole itinerary was cancelled."

Cons: "Service was curt and there was only phone-based entertainment."

Cons: "Flight connections time was not enough for mam with infant.we missed the flight should better set up that kind of big airport"

Pros: "To be fair. The flight is only 50 minutes. By th time you get a drink it's time to land. It is completely unfair to the staff to have to do that. A flight like that. Have a box with a snack and some coolers that have 5 different beverages. I wouldn't even sell booze. I person can hold out for a flight that shot to get one on the connection or in the terminal."
Cons: "It's always a cramped flight. Nothing to be done except use a bigger, more spacious plane. The good thing is it's the fastest way to get to Chicago from where I lived it would take 6hrs by car."

Pros: "Spacious seats"

Pros: "Mostly friendly staff and quick flight time."
Cons: "Only half the plane got snacks and drinks. Additionally, I was forced to check my bag, which is a pretty big deal because I was connecting to an international flight and was unable to retrieve my prescriptions in all the rush to check my bag."

Pros: "I was so happy I could check in online and boarding was a breeze. I actually got to sit by the window when my original seat was in the middle. So nice of the ladies to suggest it to me."
Cons: "No complaints"

Pros: "everything was on tyime"

Pros: "On time take off"

Pros: "A nonstop flight, with a friendly efficient crew, met my expectations. A crew member went above and beyond when I asked for a coffee stirrer with my coke and ice."
Cons: "I've been spoiled by another airline's access to screens on the back of the headrest. I have my own hand held devices to entertain myself instead."

Cons: "Flight was late, got a message from Kayak that it was delayed 3 hours...thank goodness I happened to check again, because then it was only delayed for 41 mins, then it gave me an update that it was only 21 mins delayed, then went back to 41! Pretty inconvenient, and it would have been nice to get a text, not just some silent pop up"

Pros: "Got to La Guardia almost 26 minutes early but then waited FORTY minutes for the gate!"
Cons: "AA needs better coordination with the horrible La Guardia airport"

Cons: "Delayed a total of four hous!"

Cons: "good"

Pros: "Flight was on time, staff was friendly and boarding was organized."
Cons: "I'm a small person (5'-2", 105lbs) and I didn't have room to breathe in that tiny little seat."

Pros: "Service, flight experience, entertainment"
Cons: "Checkin Personal It was delayed 4 hours"

Pros: "Smooth - trouble free - calm process"

Pros: "The food and entertainment were adequate, and the pilot did a good job of communicating the status of our delay."
Cons: "Takeoff was 2 hours delayed because we were waiting for the first officer. Surely this could have been anticipated and resolved earlier. The crew was inappropriately familiar with the passengers. We are not friends, and I prefer a bit of professional distance. The seats are designed for VERY tall people; my feet were swinging, as were those of everyone in my row. It was quite uncomfortable."

Pros: "Arrived to the airport well ahead of time and encountered lines so long that we were not able to make our flight. Only 2 attendants working and so many people had to be rebooked we didn't get another flight for 3 days. Did I mention I was traveling with a baby?"

Pros: "Excellent entertainment options"
Cons: "Wi-fi not available for most of the flight. Very uncomfortable middle seats for long flights such as this one."

Pros: "On time arrival"
Cons: "Everything else"

Pros: "Was really good flight"

Pros: "Nothing"
Cons: "The storage are very small, by the time i boarded everything was full. I had to hand carry bags and i had to put it in front of me which is a very small space already, on top of that i had the window sit so i had no space to move. it was very uncomfortable, and flight was delayed. We sat there for an hour before taking off but i understand its due to the weather but it was my worst plane ride not worth 300dollars. I will not ride american airline again."

Pros: "JAL is customer oriented and it's always a pleasant experience. Unfortunately, though the return trip is also JAL, the cabin crew isn't."

Cons: "Everything was great."

Cons: "Only suggestion would be to make the connection process a little easier. If the passenger doesn't speak English, the fact you need to print the international ticket in Miami, then re-enter at checkpoint might create confusion."

Cons: "i didnt like the food tasted like it was in a fridge forever"

Pros: "The flight attendants were great and very friendly!"
Cons: "The wifi wasn't very good so I couldn't access the in flight entertainment I also had my own snacks so I didn't buy any food"

Pros: "Personel attitude and excelent service"
Cons: "The 2 hours delay to deppart and the small room in seats."

Pros: "Seats Wifi Tv Seats again"
Cons: "Crew is so so"

Pros: "Boarding was good, Good flight , good service , plane was small for the distance with limited space for movement ,"

Pros: "The cordial treatment by the crew members"
Cons: "Not enough air conditioning, it was too warm on both flights. The foid could be better"

Cons: "No food or beverages for me. I slept comfortably on my flight"

Pros: "Plenty of leg room no entertainment so I dozed."
Cons: "People stuffing oversized bags in overhead."

Pros: "The movies"
Cons: "No Food"

Pros: "One I love free sodies and two I love free sodies with a smile. I definitely got both with this flight crew."
Cons: "Not enough sodies and I couldn't smell my own farts."

Cons: "Delayed 2 hrs"

Pros: "Frankly there isn't much to say here. After 7 flights in 2 weeks there was only 1 flight with great staff that actually cared about the customers and looked like they enjoyed their job. The rest treated guests with indifference at best."
Cons: "Customer service is dreadful, the planes are so old they still have cigarette lighter charges in first (but of course no adapters), no food/snacks of any significance, and they seemingly cancel flights at a whim with basically no staff to help re-book the lines of guests that have been disrupted. I pity those who loose luggage AA baggage services are flooded with lost baggage they just don't care any more. Seriously its embarrassing how little they care about customer service."

Cons: "The man sitting next to me had too much BO used much of my space."

Cons: "We were delayed for 4 hours, due to a mechanical issue. We were not given any forms of reimbursement. I would like a 500.00 voucher."

Pros: "The food was good. The flight attendants were friendly and provided good customer service. The flight was pretty smooth (little turbulence)."
Cons: "The flight was delayed over 11 hours for maintenance. They provided car service back to our home but we waited an hour at JFK for the vendor Skyway to arrive. The car had a bad odor and the driver didn't know who he was picking up or where he was taking us. Should seriously consider contracting with a different vendor. The next morning, after we boarded, we waited an hour on the plane before taking off while they searched for a maintenance book. The entertainment system did not work at all nor did the Wi-Fi. Overall American Airlines did a very poor job communicating the delays ahead of time. I won't be flying an international flight with AA again."

Cons: "Flight was delayed."

Cons: "Would be nice to know ahead of time if flight is equipped with an in seat television so as to be prepared to bring headphones."

Pros: "We arrived safe."
Cons: "Departure 1.5 hours late. Missed connection. Travel took 16 hours instead of 6 hours."

Pros: "All great."

Pros: "I was very pleased that the attendant gave me a free drink since I had a military ID. It was very kind of her."
Cons: "The flight was delayed multiple times. We were never informed as to why this was. It was very frustrating since I had a connecting flight into Tucson from Dallas. I got off the plane with twenty minutes to get to my next flight which was not in the same terminal. The plane was also incredibly hot while we waited to take off, I was beginning to become uneasy and nauseous."

Pros: "Zero of it"
Cons: "The fact they cancelled this flight for no reason, didn't contact me at all even though they had all of my information and than barely tried to re book me. They wanted me to take 3 connecting the flights the next day. And the next flight I was able to get on 24 hours later, I almost wasn't allowed to check in because they couldn't find my reservation."

Pros: "Airplanes are newer with onboard entertainment of all sorts for both adults and kids alike. Seats are comfortable Checking in was a very quick easy process"
Cons: "Nothing"

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

Cons: "Air Canada is by far the worst airline ever! Lost our connection flight and arrived super late after being relocated in another flight."

Pros: "Friendliness of the crew."
Cons: "There is completely no free snacks, just drinks (excluding alcohol). The maintenance didn't sign some papers for the plane which cause the unnecessary delay."

Pros: "Everything was great!"
Cons: "The overhead bin space of this airplane was too small. My suitcase, which fits on every other type of plane, could not fit on this one. I had to check it and then go grab it at baggage claim, therefore having to go through security again. This was not the most convient for a tight connection."

Cons: "Seats next to bathroom row 30 - not good. Delayed 2 hours before departure"

Cons: "Air Canada not even offering a snack on a 3 hour flight now. Ridiculous."

Pros: "On time, good staff, good dinner men7"
Cons: "Breakfast menu (omlette & chicken sausage) hasn't changed forever... 777 pods definitely more comfortable than 787-9"

Pros: "On time and all fine. Excellent service and good food."

Pros: "The flight was short . Food was pretty good"
Cons: "That we were waiting to take off and the explanation of the technical delay was not too clear and forthcoming"

Cons: "Flight was about 2 hours late, little food supplied to flight"

Cons: "Very sub par service and you have to pay extra to reserve a seat."

Cons: "crew was rude and unhelpful with delayed flight"

Pros: "excellent service"
Cons: "flight was late"

Pros: "Nice friendly crew"
Cons: "Limited entertainment; no wifi"

Pros: "Knowing that there is not enough head-room for carry-on luggage, I joined to volunteer to check-in my carry-on luggage. Service agent at the counter is very helpful and great service attitude. I asked if they have plastic twistee so I can lock my carry-on luggage before check it in. Unlucky there is none. I hope Air Canada can consider providing this ( I got from Cathy pacific before at check-in luggage counter) since they may help re-assure traveler like me who don't prepare a lock for the hand carry suitcase."
Cons: "1) Flight delay for 1 hour - that is not good 2) Choice of movie are really limited - many are old and very very old movies even though are blockbuster 3) I bought carrot and celery stick; which are wet and in plastic bag => so I cannot avoid making the table wet too! Thought it should be in a simple plastic container => even though I agree to minimal use of plastic for environmental reason. 4) The insufficient headroom for carry-on really slow the boarding time and cause delay in departure. Need better idea to help with this. may be for those who volunteer to check-in their carry on, they get a coupon for priority to board next time?"

Cons: "Because i need a visa, they don't let me abord, i can't stay even in transsit in Toronto and i didn't know, i have to change my return...."

Pros: "The crew was so attentive and respecful! Kept pouring wine as we wanted (without saying a qorf or requesting it) this is how business class should be. I love air canada business class. Super hyper recommended. Food was ok, in spite it eas a short flight. Crew was very very nice. ❤️"
Cons: "Nothing"

Pros: "The seat comfort was wonderful. And the food was great."

Pros: "I liked the fact that they provided beverages and food."
Cons: "I hated how there was NO entertainment. Honestly on a 12 + hour flight this was a bit ridiculous. No tv, or movies... no screen on the seat at all. Not even a big one for everyone to enjoy! It was horrible... The seats were so cramped and the staff seemed a bit unprofessional and sloppy looking. The food was pretty bad as well. I've had my fair share amount of flights and honestly this was probably the worse one i've gone on with the amount of hours it took to get to our destination. I wouldn't have mind too much if there was no entertainment on a 2 or 3 hour flight..."

Pros: "How the captain kept everyone in the loop about what had happened, and was able to make things work."
Cons: "When we were told that the co-pilot missed his flight to montreal from toronto, it seemed like the Air Canada crew did not plan ahead and asked where the co pilot was - aka, why did it take until we were just about to take off for the team to know?"

Cons: "There was absolutely nothing that I found to complain about"

Cons: "They sold my mom's tix. Didn't let her board. She had to buy new ticket!!! For 1200!!! Terrible experience"

Pros: "Seats comfortable"
Cons: "No overhead bin for centre section of row that my seat was in made it very inconvenient. It seemed to take far too long to offload the plane at the gate; we waited over 10 minutes for the door to open."

Pros: "It was fine. :-)"

Pros: "Nothing"
Cons: "Wifi didnt work at all on the plane to and from new jersey from toronto. I did not receive an online boarding pass once i checked in online.. i was panicked the whole day upon boarding my flight because i was limited with the time i had to wait in line. The staff on the toronto side were so distasteful and rude, never received a smile once. Not to mention they confiscated my 300$ face wash system.. I understand now the restrictions to bringing over 120ml bottles but they refused to even pour out half the contents (which they took into consideration on the toronto side) my bottles were only 125ml.... what a joke this airline is. i was flying alone and hadnt travelled from an airport in 15 years- emails i received DID NOT specify the restrictions of what you're allowed to bring in carry ons. how is someone new to this experience supposed to know?????????they simply told me there is a website i can go to to see the restrictions... but that website is not mentioned ANYWHERE. The airport staff were extremely rude and cold while ripping apart my bags because of toiletry bottles. I have an extreme anxiety disorder that made me have a panic attack during the baggage inspect and I was given looks as if i was crazy. absolutely disgusting people working in the airport environments. They caused me a world of stress. I will never in my life fly Air Canada again."

Cons: "Long line and few staff at immigration. Need twice number of clerks"

Cons: "No complimentary snacks"

Pros: "Entertainment screens really helped to pass the time away and keep the mind busy. The crew was helpful when needed. I needed an extension for the seat belt and the person next to me got the crews attention and I received one before take off"
Cons: "Found the leg room tight in economy and hard to move around. Hard to stretch legs out. Need more leg room."

Pros: "Flight from STL to YYZ was unremarkable, which isn't a bad thing when it comes to air transportation. Bit of a delay leaving, waiting for de-icing trucks to show up and do their work, but I'm not sure that's Air Canada's fault."

Pros: "The flight had to abort take off due to an issue with the pilot seat. We had to return to the gate for them to fix the problem. Left the gate a second time only to sit on the runway with no explanation from the pilot."

Pros: "Not certain the type of aircraft used for the flight from Orlando to Toronto, but it had more leg room and more comfortable seats that the flight to Orlando which was on an Airbus. The seats were a wee bit wider and the extra few inches of leg room made the difference between a completely unbearable flight and one that was "poor." (See comments about the crowding and heat.)"
Cons: "We were returning after a cruise, spent part of the day on a shore excursion before being dropped off at the airport 5 hours before our flight. There was no rep at the check-in counter until 3 hours before the flight which meant we had to sit in the terminal for two hours. If they could have had one rep on duty to check in early arrivals, we could have proceeded through security and spent time in the MCO Lounge which would have been more comfortable than the terminal. Once their check-in counter opened it took about 2 hours to clear that and security. Once on board the sold out flight, we were told it was too cold in the front of the plane; while in the back it was baking. For a flight departing Florida, I would expect the airline to have A/C running before we boarded."

Pros: "We arrived safely and on time."
Cons: "I did not get airline miles credit on my United account as requested. I would like to be contacted about this."

Cons: "The Crew Was rude. the seats were small, NO TV's, for a 10 hour flight. Had to "rent" a iPad. I was not able to download movies on my own device. Had to pay for drinks, on an international flight, Are you kidding me!!?? I will never fly Air Canada Rouge again. Very disappointing."

Cons: "We never got on this flight because we were delayed due to an emergency landing. Couldn't get anyone to help us get home sooner than 24 after when we were originally scheduled to be home in Nashville."

Pros: "Service was good and people were nice."
Cons: "Almost no room if someone puts their seat back, food was not good, made an emergency landing when passenger said he was fine and caused everyone to be delayed."

Cons: "At least two hours delay departing three of four times, virtually no air on the Toronto-Nashville leg then had to sit on runway in a hot plane due to gate not being ready. The international boarding from Toronto to Paris was badly disorganized with two gate attendants and finally another two came over to help but stayed in phone most of the time. We were already delayed. Won't fly Air Canada again"

Cons: "Lavatories didn't flash properly. No tap water"

Pros: "Very smooth easy flight there were no delays!"

Cons: "Was an overnight flight and not very comfortable but didn't expect anything different."

Cons: "The customer service when our flight to Boston (connection) was atrotious. I will never fly Air Canada again"

Pros: "Good Crew The crew was sharp, efficient, attentive and very good."
Cons: "Better Food Needed Even though this was a short flight, the meal could have been better. The small amount of smoked salmon was inadequate. This meal has been served over and over. Increasing the amount of smoked salmon would at least be a step in the right direction."

Pros: "My scren was´t working ok, and the screen of my sister seat was in ¨wait please..¨ half of the trip. The boarding wasn´t on time but the crew memebers where really nice. Overall okey"

Pros: "The fast boaring"
Cons: "The 3hr delay. Not many announcements. No one at the gate/desk. Had to be in a crowded gate area with no choice."

Pros: "Nothing to like about this airline. Horrible people especially in toronto, really unhelpful, extremely rude."
Cons: "Air line decided they didn't want me to take my connecting flight. Removed my luggage without consulting with me. Offered me a disgusting hotel. Forced me to pay out of pocket for food, taxis, transfers and my own hotel choice. Staff were so rude. No explanation to why they removed my bags. I made it in plenty of time for my connecting flight but airline had just decided. No staff member was interested in answering my questions or helping. They all just wanted to sod off home. they just didn't care."

Cons: "Air Canada lost my luggage, customer service was very vague and unhelpful, did not get my bag back for almost a week."

Cons: "Very slow service"

Cons: "We took off 1 to two hours late"

Pros: "Plane arrived pretty much on time. Boarding was uneventful."
Cons: "Plane too low to use jetway at Pearson. Epic walk from US gates to immigration. Insufficient leg room if you're over 5'10", but that's how it is these days."

Cons: "My seat back was not reclining for the entire 9 hour trip"

Cons: "First time flying air canada and flight was delayed 1 hour"

Pros: "Very good service"

Cons: "Too cramped and no flight entertainment"

Pros: "Lots of leg room for a regional jet."
Cons: "AC was not very good. Very warm on flight."

Pros: "Easy"

Pros: "The service was prompt and professional. The plane on this trip was clean and in good repair. The snack was simple and tasty. It was a pleasure flying United."
Cons: "The first flight from St. Louis to Chicago was very small. While I don't have concerns about flying in a small plane, I can imagine those nervous about air travel would feel concerned with the size of the aircraft."

Pros: "Good communication and helpful."
Cons: "Delays"

Cons: "Luggage compartment too small even for a rolling laptop bag"

Cons: "Flight was cancelled. I am still stranded and was given no accommodations so had to pay for a hotel in addition to costing me a full day's wages in missed work.

Cons: "I only wish your branded credit card did not cost$95.00 after first year."

Cons: "super cramped quarters, like touching legs to the next person the whole squirmy flight close... the plane was made for little people."

Pros: "Flight was on time"

Pros: "Departed close to on-time. And as a pilot myself any landing you walk away from is a good landing."
