Cons: "1. Limited legroom and space. 2. Would like additional cabin service for water etc. Also would like a non-dairy option for breakfast."

Cons: "The crew blocks economy passengers from moving forward until all of first class has left. No other airline does this and its really annoying"

Cons: "Sloppy cabin crew at the time of embarkation. Bad entertainment system (horrible touch screen, earphones with loose contact), made a 7 hours trip an unforgettable experience. Food quality was marginal. A drastic contrast with the previous flight of the same airline company (but from Amsterdam to Istanbul), which was very good."

Pros: "The only thing that I liked was that I got to spend time in Turkey which is beautiful and had friendly people outside of the airport."
Cons: "Customer service sucked! Especially in Amman and Turkey . No one would help you when you need it in the airports and their desks are not open long enough to get the help that you need in Amman. Also, when you ask the information desk at the airport in Amman to call someone from Turkish Airlines they tell you that they can't because they won't come. I hope that this feedback would be used to make the airlines better because Turkey is truly a beautiful place."

Cons: "Little value for money. Meal, seat.. below expectations of premium economy"

Pros: "Top notch service on the airplane"
Cons: "None"

Pros: "everything"
Cons: "-nothing"

Pros: "Great choice of entertainment, food relatively good for plane food."
Cons: "Crew was fine but not as friendly or cheerful as I'm used to flight attendants being. The leg room was pretty poor on this particular plane, there wasn't even space to put a small bag under the seat in front of me."

Cons: "I had a connection from Istanbul to Frankfurt with Lufthansa . I was disappointed that TK airlines did not allow me to check the luggage through to Frankfurt because the flight was on a different ticket . As an Elite Plus member , I expect better cooperation among the star alliance member airlines . I had to check out and back again , took almost two hours of waiting in lines .

Cons: "That the anytime snacks that was offered was not available for passengers"

Pros: "I liked the entertainment options during the flight."
Cons: "1) Since we had a long layover at Istanbul, the airline provides the option to take you to a free hotel to spend the night. I knew this information based on online reviews, but the airline itself never did anything to offer this, I had to walk around on the airport, for like 2 hours I could not find decent help and some instructions in broken English. I had to pay 25 Euros to get mi visa stamped and walk out of the airport. The Turkish Airlines attendant that set up the free hotel for us, walked us to a shuttle that would drive us to the hotel, but the shuttle driver got lost? or something happened that caused for him to drive around town for more than an hour, speaking on the phone loudly in Turkish and completely ignoring us when we asked questions, This got a little scary since we had no idea what was going on, at some point we were in the middle of a dark residential area, and listening to the driver yell on the phone (god knows what). Luckily a driver came over and guided us to the hotel, but seriously, they should be careful about who they hire for these kind of tasks. (I posted a video on instagram with footage of the guy driving us around in case my family needed to find me)."

I would love to have another free flight or I will post the tickets on facebook, Twitter and etc... To make a terrible flight reputation."

Pros: "Seat was comfortable, food was good."
Cons: "The woman seated next to me was the mother of one of the flight attendants. She had terrible body odor that nearly brought me to vomiting—and this was a 10 hour flight. She was also brought all kinds of amenities from the attendants from the 1st class cabin—not really appropriate."

No babes the entire time I was in Germany. Arrived in Mumbai after paying the $350 US change fee and no bags.

Cons: "It wasn't an issue on my flight since there were empty seats in my row, but I don't enjoy the spacing provided for personal items on the floor under the seat in front you. For four seats there are three sections; so, you can hope that someone doesn't need any space or else you have to decide how to awkwardly split it up."

One child had one on tye chair and I asked him if its suppose to be on the seat or given later on. He said it will be passed later and then with a patronizing manner he gave another head phone set and said: "I guess we havw an emergency". On the flight, every time he with the food and drinks he just stood there next to me talking over my head with the passenger begind me. Very uncomfortable, especially when it happens 6 or 7 times. When asking what drink we wanted ( the first time), i replied apple and orange juicewith no ice. He replied, with a patronizing manner "this it European company, not American company. Here we don't put ive if you do not ask for it".The incident that bother me the most is one that involved my kids also. My daughter (3 years old) was a bit scared of the flight, tired and did not want to sit on her chair. We tried to keek her on the chair buy she started crying laying down on the floor infront of our seats. Jorge the flight attendant saw her and told me to put her on the seat. Not in a manner I expect out of soneone in the service industry. I told him we are working on it and we will have her on the chair as soon as we can. When I said that he got irritated and a bit aggressive. For no reason the situation became hostile. The flight attendent on the other side (do not know his name). Can over and asked us what we needed amd if we need help. I told the other flight attendant we need 5 minutes and he said OK. After a few minutes she calmed down. Anotger passenger asked Jorge what beer it is and he replied, with contempt, " its German beer, its good"."

Pros: "Pleasant crew."

Cons: "British Airways is the only airline I’ve flown that doesn’t off free water."

Pros: "The crew was very friendly. Lots of movie options. I got a voucher due to the delay."
Cons: "The delay was a bit of a bummer and it would have been nice to be compensated with more than a voucher that couldn't be used in LHR because it was in USD. I also would have liked to been told they were still planning on serving dinner despite the midnight departure; I fell asleep because they turned off the cabin lights and I assumed the meals had shifted, but instead I missed out of my dinner. Lastly, I am quite petite and still struggled with legroom."

Pros: "Crew was friendly and helpful, food was ok."

Pros: "Orderly boarding and disembarkation."
Cons: "This airline is one of the worst in Europe, for the simple reason of putting short-term profits ahead of decent treatment of the customer. My flight across the Atlantic was 4 hours late, and BA refused to put me on the next available to Prague, even though the lateness forced me to miss the BA flight I have been booked on. Their reason referred to a technicality in the booking procedure, but actually BA has put in place "policies" aimed at their financial advantage, over and above reasonable treatment of the customer. BA's refusal to rebook me cost me a lot of inconvenience (3 hours on the phone, for one thing) plus about $150 (I am taking another route to Prague); BA was then able to sell both my original seat and an extra seat on the next flight from Heathrow to Prague. I will never fly BA again in my life if I can help it."

Pros: "On board service and amenities"
Cons: "Kayak customer service"

Pros: "I like to fly BA because the crews ( and I assume the maintenance) are top notch"
Cons: "Tired old 747. Needs an upgrade. Packed in like sardines on an old plane that shows it age. Should have flown Norwegian. Major delay caused me to miss my connections though the BA staff were all over it."

Pros: "I arrived safe and sound"
Cons: "Even though I purchased an exit row seat we were packed in like sardines. I know airlines have to make money but that flight was ridiculous. also, the plane was way too warm for much of the flight. Not sure if there was a problem with the air but for these prices...fix it please."

Cons: "N/A"

Pros: "it was very clean on a board."
Cons: "even water for money"

Pros: "The seat was comfortable and featured the good headrests."

Pros: "Excellent food and service."

Pros: "Boarding was good, the crew were friendly and accommodating."
Cons: "In flight entertainment didn't work at all for the first hour, after that it was mediocre. It was so hot in the cabin that there was no way to sleep. No air vents to cool you off. The window covers were broke and some wouldn't close. They also rattled...very annoying."

Cons: "Plane was honestly very dirty. There was a ton of crumbs and gross stuff in th seat back pocket. Which I did not even use because I didn't want any of my things to touch. The overhead lights were covered in dust. So make sure you have some some type of cleaning wipes with you!! I do understand that I was flying economy, but that doesn't mean nothing should be cleaned."

Pros: "Clean plane"

Pros: "Seats were comfortable and staff was very attentive as well as respectful of us when I was sleeping"

Pros: "Fligth attendants of British, Iberia provided excellent and friendly service. Some of London British Airways desk and gates officcers, gave me really poor service."
Cons: "My flight to London was pretty good,. Service was excellent.. But not my transfer to Madrid , I lost my conecttion. On London airport, I was sent back for the gate because I showed up early and they ask me to take care of the screen and wait for the gate #, when they showed the # , I went to the gate and was told my flight had left an hour ago and sent me back walking . I was wearing an orthopedic shoe, due to a toe fracture and i had to walk again all this long distance back to the terminal.!! British airway gave another flight and had to pay $279 dlls for a ticket to Madrid.2 hrs later. My flight was by Iberia and the service. was excelent. I wonder if the insurance , I bought initially will cover something of the $ 279 dlls ticket ? Fligth back to EUA was by AA and service was excellent"

Cons: "The seats on these flights are poor. As well as being narrow, there are bars on either side that dig in to your sides. My ongoing one hour domestic flight had more comfortable seats. Fod choice poor. Chicken Curry or Cheese/Tomato Lasagna. If I want a vegetarian meal I'll order one beforehand. Give me two meat options. This isn't the first time I've noticed this. Is it cost cutting? Seems like it to me. Not impressed."

Pros: "Very courteous attendants"
Cons: "All good"

Pros: "I loved the legroom in the emergency seat I had and the service was top notch. The food and food choices was also really nice and the wine served with dinner was great."
Cons: "Overall loved my emergency row seat the only negative for my particular seat was once the rest of my row was filled in and the 2 seats in front of me it made it impossible to get out of the seat and stand up unless I could had the person sitting in front of me get out of his seat."

Pros: "Clean, not crowded, and the crew was friendly."

Pros: "Everyone was awesome"
Cons: "The staff was awesome"

Pros: "The food was elevated and we were fed twice on our 9 hour flight! The beverage service was also provided often with a good assortment.

Cons: "Nothing."

Pros: "Wine with dinner."
Cons: "No tv for 9hr flight. Breakfast was awful."

Cons: "We purchased upgrades to an exit row seat because my knee locks up when cooped up for that long.

Cons: "Did not purchase food or entertainment."

Pros: "For economy class it was good seats (bulkhead), the crew were nice, and the food was good."

Cons: "No"

Pros: "I used frequent flyer miles for the tickets."
Cons: "The crew was late getting to the gate. All of them talked to me like I was a child they were disappointed in. No one smiled. I thought all of the crew was mad at us for using their airline."

Pros: "Nothing."
Cons: "Everything"

Cons: "You were out of earphones"

Pros: "We were allowed to board early with my father, who is disabled."
Cons: "Denver airport was a nightmare with my disabled father. We were given a “wheelchair” but no escort through a nightmarish security scene. Airport is terribly designed, lacking clear signage and navigation. TSA was a disaster and no one seemed remotely concerned about my father’s comfort or needs."

Cons: "Less boarding groups"

Cons: "I researched and called and found a 45L backpack so I could carry on my dive bag. That’s the reason I’m going all the way to Fiji. Not letting me get it in LA I’d also ridiculous."

Pros: "Food was good. Staff was polite."
Cons: "Both flights were late leaving. Plus then we waited on board for a long time. Once on board and waiting, no explanation, no updates. No idea what was going on or why. An announcement would have helped a lot. Philky-Prg: Long delays with food , staff was slow on the Philly -Prg flight. Seemed like they didn't want to be there. No info from flight crew. Phily to Prg - Crappy old plane that should not be flying over seas anymore. Applies to both flights unless specified."

Pros: "Nothing!"
Cons: "Almost everything!"

Pros: "Pilot made up time so we made it in early!"

Cons: "The bumpy ride"

Pros: "Crew was nice and friendly. Pilots flew great. We arrived a few mins early as well."
Cons: "On the way to Denver from Miami we were on a nice new AA plane with TV entertainment, movies, power, and comfortable seats. On the way from Denver to Miami we were on an old plane with no entertainment and old uncomfortable seats. If this is going to be the case, charge me less up front as well. My daughter had a terrible time for a 4 hour flight."

Pros: "On time. Efficient boarding."

Cons: "Girl next to me being sick the whole time"

Pros: "Getting through security was a lot better than I thought. Also, I had plenty of room and the overall ride was smooth."
Cons: "I just wish that there was a little more room and easier ways to earn miles and entry into the lounge."

Pros: "Wi fi did not work."

Cons: "Sitting on the runway after landing because the gate is occupied."

Pros: "No surveys"
Cons: "No surveys"

Pros: "El problema es que el vuelo estaba sobrevendido y han cerrado las puertas antes con lo cual me he quedado abajo sin pode abordar. En el aeropuerto de Denver habia solo dos personas en el securty check por lo cual la demora fue involuntaria en mi caso. Cuando estoy haciendo la fila para ingresar al avion (esyando en la misma cola antes de ingresar) me informanque no podre embarcar..(claro ya habia designado mi billete a otras personas. pesima atencion y pesimna experiencia con los empleados de ese vuelo. Denver a Miami"

Pros: "The Denver airport is beautiful"
Cons: "I will never fly AA again - see below"

Pros: "Love the movies!!!"
Cons: "Passengers are allowed to take too much on the plane, which makes boarding & getting off take WAY TO LONG. If American would follow Southwest and allow 1 free bag, this problem would end. E"

Pros: "On time, friendly and helpful staff at airport and on aircraft"
Cons: "Nothing"

Pros: "Overall great flight and great service. No complaints!"

Pros: "I liked everything from the way they got everyone on the plane to getting everyone deplaned."
Cons: "I didn't have a problem with the airline. Just a couple of passengers."

Pros: "On time. Good crew and nicer flight."
Cons: "Actually no complaints."

Pros: "Friendly service"
Cons: "Snacks"

Cons: "American delayed the flight 7 times before cancelling it. They then put me on a flight 7 hours after the initial departure time. That flight was delayed 7 times and then they cancelled it. I wasted 10 hours at the airport."

Pros: "Very nice crew!"
Cons: "Was almost three hour late..."

Cons: "Food had little taste. Movies were not that current and selection was sparse"

Pros: "Crew was great!"

Cons: "Main meal was the worst I have had in over 10 years on a plane. I got the pasta. There were no vegetables or color other than yellow/orange in the dish. The side was a potato salad, which is also not very nutritious. Then you get a brownie and a roll. The breakfast/snack was also a pumpkin slice of bread. The overall food options were not very diverse in terms of the food groups. I thought plane food had improved in the last decade or so, but not on this flight."

Pros: "No leg room"

Pros: "Cabin crew were terrific!"
Cons: "The unfortunate delay of our flight. And the entertainment systems seems to be getting old. What I mean is that it is by todays standard very very slow to switch between menus etc. And in some cases did not display all the menu content."

Pros: "very nice crew"
Cons: "plane was too small and there was 1.5 hour delay departing"

Cons: "Rouge flight was sub par"

Cons: "I think the air quality on the flight from Toronto to Seoul was bad. I felt really neaseous for most of that flight and thought I would be sick on the landing. the illness went away completely once I landed and I didn’t experience it on the Asiana flight from Seoul to Phuket"

Cons: "Some of the crew was a bit rude and snippy"

Pros: "Not much. Crew was good but that is about it."
Cons: "Tight spaces packed in like sardines. FAA seriously needs to look at how these airlines pack us into these seats. Can barely sit in the set, no room to stretch legs, tray table hits my stomach, and I don't even have a big belly. When the guy in front reclines, cannot even get out of my seat. Chaotic boarding process without any order or instructions or announcements, poor food and entertainment."

Pros: "The full experience"

Pros: "Good boarding.Easy check in."
Cons: "Food! Not appealing. Did not eat more than a few bites."

Pros: "1 stewardess was great"
Cons: "Flights were delayed. Did not check boarding passes which was scary."

Pros: "The flight crew were helpful and friendly"
Cons: "I was forced to miss my second flight because the first airplane malfunctioned"

Cons: "Rather than notify the passengers that our flight would be delayed prior to our arrival at the airport, we waited at the gate for several hours."

Pros: "The crew was professional and friendly."
Cons: "The return flight to Orlando was just shy of 2 hours delayed. It was delayed 30 minutes prior to boarding. Then we sat on the plane, at the gate for over an hour. The plane was absolutely filthy. There was food on the seats, on the floor, smears on the window. It was disgusting and I could not wait to get if that plane. I will not be choosing air Canada in the future."

Cons: "Our direct flight to Montreal was canceled due to mechanical issues. The rebooking process was discombobulating and we ended up arriving at our destination after the rerouting that was stressful and ensured that we lost a whole day of our vacation time. Our flight back the entertainment system in our seats did not function."

Pros: "put us up in decent hotels gave food vouchers the crew didn't do anything to make it horrible Large selection of movies/tv on board comfiest seats out of all the major airlines I've flown"
Cons: "The flight kept getting delayed bc of mechanical problems, and then eventually cancelled. They rebooked everyone on new flights, but it took an extra stop in Toronto before getting us to Montreal. Once it was rebooked for the morning, it took off a little late. Plus the pretzels they gave us were stale. This was the first of two flights I took this trip that had mechanical issues, so they obviously need to fix their planes better or get new ones, because two Air Canada flights in one day that have mechanical problems leaves me worried that the planes aren't in optimal condition. It took me over 24 hours to get from Tucson, AZ to Montreal, Canada when normal travel takes less than 8 hours including layovers."

Pros: "I had an aisle seat"
Cons: "The plane sat on the runway in Denver for over an hour because they couldn't figure out their furling situation. Many people nearly missed connections because of this. The crew never let us get up to go to the bathroom on an international flight because of some small turbulence."

Pros: "Nothing! Unpleasant unhelpful crew at gate, no better onboard, absolutely moist cramped seating ever! Disorganized and late- boarding, departing, waited to disembark at arrival, 25 min before first bag off baggage......dreadful no one cares"
Cons: "Thank you for choosing Air Canada- smiles and goodbyes- where's all that Before you leave? They treat you like problem cattle to be dealt with, you're anonymous and valueless until you leave then they look at you and thank you?! Missing sincerity And service!"

Pros: "Onboard attendants were pleasant"
Cons: "No apology for lateness, flight boarded late, took off 40 min late, arrived 35 minutes late but we sat at gate waiting for someone to open it ?!, then another 15 min before bags started to unload Ridiculous but indicative of airlines You are not their valued guest or even their customer, you are a problem that needs to be solved and are consequently met with preloaded annoyance and a readiness to dismiss, placate at the best of times but definitely not please, impress, sympathize or satisfy. There is no evidence that it's even in their lexicon- not a part of their recruitment or selection process or training, ever! They're main focus and only positivity is saved for themselves. There may be a long line of concerned and anxious travelers but their priority is getting coffees for the battle ahead! They break their focused indifference only for each other and enthusiastically leave their post to satisfy each other's needs and attention. This has got to change! Why do we put up with such awful service for which we are the paying customer? Why are we, their customers, not valued? This airline makes record profits, provides less, charges for everything and increasingly delivers bad service, sometimes offensively bad! It doesn't cost more to hire a customer centric pleasant person, or incorporate guest experience into training or at the very least be friendly and smile! What if an airline just did that?! They'd differentiate themselves and develop a positive customer centered culture. Don't we deserve that, at the very least?!"

Cons: "Crew wasn't helpful and attentive, boarding staff in Toronto were blatantly rude to me, I watched as my luggage got handled aggressively, the plane was dirty with old food crumbs and such, my flight to Windsor got cancelled and accomadations were not met sufficiently."

Pros: "Flight was on time. Personal entertainment is very good and crew was great."
Cons: "Boarding is always a bit chaotic with the carry on bags. I am tall, so economy seats are always uncomfortable."

Pros: "The flight was perfect. Stress free. I will definitely get it again."

Pros: "I like that Air Canada provides entertainment and its flight attendants are really good."
Cons: "I rarely fly these partner airlines without experiencing major delays, and the delays are always announced after I have cleared security, forcing me to spend hours at the airport. The claims of "weather" are specious: they don't fly enough planes and they don't properly maintain the planes they do fly."

Pros: "Online booking,boardong pass, alerts"

Pros: "Right on time. No problems boarding"
Cons: "No food/entertainment"

Pros: "Crew was nice"
Cons: "Couldn't use in flight entertainment, only half a soda was given"

Pros: "Nothing"
Cons: "Customer service flight rebooking"

Pros: "The plane, which was American-made. Smooth ride in the air, no baggage issues."
Cons: "The crying children in front of me, the hour and a half delay, and the late dinner service. Dinner came at 8:30, after staring at those with special meals eat and finish an hour before everyone else, they should wait with the rest of us. Breakfast was pretty lackluster. Their online app and check in is awful- they should hire new coders and UX designers to increase functionality."

Pros: "Let the announcements be delivered in both language successively."

Pros: "Boarded and arrived on time."
Cons: "Too much waiting at Toronto airport"

Cons: "No monitoring of travel route"

Cons: "There wasn't a food in the International flight. Air Canada is so crazy!"

Pros: "An Air Canada rep over the phone"
Cons: "Gate agent, zero entertainment (and no warning that we should download an app inside airport), poor food, flight attendant wouldn't bring coffee to us (made us go to the back)"

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

Pros: "Upgrade to premium economy with more legroom. Free movies. Good movie selection. Free checked luggage!"
Cons: "Check-in process at Denver counter rather slow. Gate information at Denver very confusing due to changes and lateness in displaying/announcing information."

Pros: "I enjoyed the entertainment option."
Cons: "Wish there were more choices for new movies."

Pros: "nothing"
Cons: "i booked a flight through kayak going from denver to milan. i showed up at the airport in denver to fly out yeserday only to find out that i was going to frankfurt germany. i am now in munich germany and never made it to milan. i was one of many people i met on the flight that also booked with air canada thinking they were headed to milan. air canada kept trying to put the blame off to my booking company. i don't know who to be ticked off at. please advise."

Pros: "Great crew. Nice airline."
Cons: "Both flights were over 30 minutes late. Otherwise they were just fine."

Pros: "Better plane than previous"
Cons: "Had to be rerouted to Calgary because I missed my connection"

Pros: "Great crew, delicious samosas! Awesome selection of movies"
Cons: "I'm skinny but tall and it is my opinion that these seats are uncomfortably small/narrow The room UNDER the seats is smaller than in other planes as well, so it's tougher to stow your gear"

Pros: "Nothing."
Cons: "The flight attendants on this flight did NOT do their job. If they are there to ensure a safe environment for the people on board, they completely missed the boat. I was in row 45. Two families were on board with their 4 very young children. For the entire 8 hour flight, 3 of these children disrupted the entire section of the plane. They continuously played in the aisles, stood in the seats, kept their seat belts unbuckled, threw objects, and one blasted his iPad at maximum volume. When I asked one flight attendant to ask the family to get the child to lower the volume on his iPad (it was 4am; people were either using their ear buds, or had their screens turned off), they complied with the request for 30 minutes, then resumed at full throttle. I can honestly say, it was one of the worst flights I have ever experienced in 57 years."

Pros: "There was entertainment on board although it was very limited. All of the crew were very helpful and professional."

Pros: "crew"
Cons: "delayed due to computer malfunction, food awful, missed my connection, had to wait for 6 hours"

Pros: "Everything was well organized and we were able to depart sooner than scheduled."
Cons: "There were some items on the menu that were not actually available."

Pros: "Flight was underbooked so I took an option to change my seating for more space."
Cons: "I requested a vegetarian meal and was given the exact same mediocre meal for both lunch and breakfast."

Cons: "We were not allowed to board at EWR for want of Canadian transit visa. KayaK or Vyama never informed us us about this requirement We are Indian nationals. SimIler to us we saw two more families stranded at EWR who have come to catch the same flight.They have all booked this flight through Vyama/Kayak. Two senior citizens"

Pros: "AC changed to a different plane for our flight at the last minute, so seat assignments were messed up, and we had paid extra to choose seats. So why pay extra for seating when the airline can put you wherever they want at their discretion. In addition there was a minor delay in take off while the flight deck crew had to re-programmed the avionics to our scheduled route. But we made up the time en route and were only a few minutes late. On the whole, not a bad flight experience, just the usual frustration in the process. I long for the days when flying was a pure pleasure."
