Great service, great food, and comfortable business class seats... Friendly and professional flight attendants and ground crew, overall 5 star experience!

Movie selection was ok, but could be better. Would like to see greater selection of newer movies.

Loved the check-in experience. Very friendly staff and not crowded. I did wind up with a middle-middle seat, which was quite uncomfortable. Always appreciate the very professional staff on TAL.

Paying for reserved seats and never received the seats I paid for !! Just fake and a surprise out of their " box "

Turkish airline always good Only Turkish representatives at the gave need to be more helpfull to any staff who traveling on Turkish airline . One situation happened Ist to jfk on Feb 29 TK3 had seats I asked them to transfer me to tk3 because Feb 29 tk1 was oversold and they advise me that I might not make it for tk1 I asked them to transfer me to tk3 and they say no they can’t do it I been telling them you know that I don’t have a chance for tk 1 why would you let plane go with some empty seats on tk3 if you can transfer me to tk3 and have less staff on tk1 and still told me no I waited for tk1 9 hours and only last minute I got seat on tk1 It was not easy situation but I am glad I made it home Thank you Turkish Airline One more suggestion for Turkish Airline you need to make a FIRST CLASS cabin it would be so cool 🆒 Good luck all the best See you more

First class payment but wife’s seat broken, would recline but not lay flat. On previous flight, delays and ground crew malfunctions connecting jetway made us miss flight to Houston. I asked twice for a cart to assist us getting across the massive Istanbul Airport, but was denied. We are both over 70.

My flight had two legs. When checking in at the first leg the agent offering for a deal to upgrade the leg to first class for $199. He then claimed I would be able to upgrade the second leg once I got to the next airport. I declined and when I inquired about upgrading at the second airport, the cost was $1,300. I also had an issue at the airport lounge. I am allowed one guest in the lounge. My friend came in the lounge for less than 5 minutes and left when she couldn’t get a sleeping suite. I wanted to bring in another friend. The airport staff first started acting as though they didn’t understand English and then became upset when I asked for their names so I could file a complaint. As an elite member I knew they could do more but were not. One of the agents started over talking me and walked away mid conversation dismissing my request for assistance. A man claiming to be the manager said you were asking for her name. He also never tried to assist me or see what was going on. He claimed the interactions were recorded and management would see everything. I’m not sure how that would assist me days later. I am sure it didn’t help that I was a black American woman.

Better attitude training for staff at airport, better training for flight attendants, better food, don’t put us with all the crying babies that cried nonstop for 12 plus hours.

Crew announced boarding started and they asked passengers to form a queue. Actual boarding didn’t start and queue was not moving for around 40-50 mins. Very poor management.

It was a terrible airline. The air hostess and the people in the flight, just very rude.

I was not expecting much as i was not in a premium cabin. I was pleasantly surprised that the seat in economy plus was spacious and food was ample. Party of 5 with 2 parents and 3 kids.

Outstanding in all respects. Early boarding left early arrived early. We were in business class, so was perfectly fine.

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

Dinner was okay but the breakfast was not eatable on the flight San Francisco to Zurich.

I really do not like the basic in basic economy.

There was no screens on board AND the WiFi didn’t work. My seat was broken and couldn’t recline so I couldn’t even sleep. The flight attendants didn’t offer anything to make it more comfortable. It was such an old cramped plane, when the person in front of me reclined I couldn’t even open my tray table. All the United ads talk about guaranteeing everyone gets a screen!

The Wi-Fi was unavailable on this flight for some reason.

On time take off…US cabins look tired and need of refresh!

Marked by flight delays on all segments of the trip. Food in first class cabin was mediocre and overhead cabin storage was not adequate. Overall, the premium charge for first class cabin was poor and over hyped. This will be our last flight with UA.

Fantastic. Smooth boarding with an infant. Never experienced it with any other carriers.

Will try to not fly with them again. Delays because of weather but got redirected to an airport where I could not make connection.

Staff didn’t care in business class. Closed the door on my mom while she was on the jetbridge and flight attendant told me she would make it from the connecting flight. They lied. My luggage was damaged on arrival. No success in filing damage claim.

Crew was super rude in business class. Not friendly or helpful. Luggage was damaged and was told to file with United and that was unsuccessful.

The connection at Frankfurt was chaotic and nearly missed the flight to Atlanta. They made was wait for busses to transfer and it took ages

There was a screaming child just behind our seats. This prevented us from getting any sleep during the night!!

my flight was at 3:45 after that they delayed to 4:40 I have transit from Chicago to Frankfurt and Frankfurt to vina airport from vina to Erbil buy the Time I come to Frankfort my other flight left me I have to stay at airport all day with my 5 kids ask for help no one help me I spent at airport almost $450 just for food was horrible flight ever I call and ask for hotel from united customer service they been telling me we can’t provide any hotel I need some refund or fixed my flight when I return to America need some one respond my email

My experience would have been greatly improved by arriving on time to connect to my Porto flight. The staff that dealt with the aftermath of the late arrival evidently booked my group into a hotel in Frankfurt. This reduced my time in Porto Portugal a day and half. I do want to commend Jorge Klein for his hard work. He spent a great deal.of time trying to rebook the flight and he eventually did rebook for the next day and did provide accommodations for me overnight. This was a big issue for me and the group I traveled. The rest of the trip was good.

Not your fault…..didn’t get my drink until just before landing….bumpy flight.

Boarding was a zoo. London ground crew was useless. Poor communication regarding where to line up. We were group 2, and everyone was jammed in together. Ground crew didn’t seem to care.

We liked the direct flight from Frankfurt to Orlando, however, it was a little confusing as I thought I was traveling with Lufthansa from Izmir- Frankfurt-Orlando. We were not able to check in online twenty-four hours before the flight from Izmir. One lady in our group wanted to check two suitcases in Izmir, but was not allowed to do so. She was allowed to take the extra bag into the cablin. Others in our group were able to check two bags. In Frankfurt several in our group were given stand-by boarding tickets, which worried them. Everyone eventually was allowed to board, but it caused them to worry. I didn't have any of those problem.

My worst flying experience so far. This flight was delayed a total of 42 hours and diverted to New York before it was finally cancelled. It was delayed 4 and a half hours in London. As we were scanning our boarding passes at the gate they advised that the flight was being diverted to JFK since the delays caused us to missed the open hours for Charlotte international customs and immigration. We were assured multiple times by airport personnel, flight attendants, and the Pilot that we would land at JFK go through customs and immigration and then reboard the plane to fly to Charlotte in the same night. When we landed in New York the pilot advised us as we were retrieving our carry on luggage that we were delayed till 10am the next morning and to see guest services to get a room for the night. During this time I had to purchase a room for a family member in Charlotte which drove over 4 and a half hours to pick us up from Charlotte. This could have been avoided if American Airlines had been up front about the delay. Then after standing in line for over 2 and a half hours at guest services we were taken by taxi to a hotel 30 minutes out of the way. Luckily I looked for other flights that night and found one at 8 am to get on. The initial flight which we were scheduled to fly to charlotte in was delayed 12 more times and was finally cancelled 42 hours after it was supposed to land. I am unaware of what happened to the guest that were supposed to fly on the flight after we were placed on another flight but 42 hours in delays for a direct flight is absolutely ridiculous.

The boarding to Gatwick was a breeze but the boarding from Gatwick was a nightmare. The onboard service to Gatwick had a lot to be desired but the onboard sevice from Gatwick was amazing ! Very nice,friendly and funny ! Would I recommend BA to anyone.? ! Yes I would!

Is it American Airlines or British Airways? This is so confusing. I got it from Portugal.

Appreciate free wine and entertainment plus good meals. Also leg room

Really quick check in and security at Heathrow Terminal 5. Staff on board were lovely and very friendly. Could have provided a few more drinks on the flight but they were available at the back of the plane.

they are improving. The crew from Charlotte to Tampa was outstanding. SMILING and trying to be helpful with the customers.

It was a flight operated by Aer Linus for BA and the plane and crew were very good but the food selection was average.

I like the food this time compared to my departure. I’m seated at the isle so it’s comfortable but I have to pay $124 for seat selection

Flight delayed an hour due to plane maintenance issues after getting in line to board. Issue was plane galley ovens which eliminated hot meals for overseas flight. Cold selections were limited due to availability. Drink and meal service (already an hour delayed) was very slow. Upon arrival in Nashville, had to sit at gate for about 15 minutes before disembarking with no explanation. Local police then boarded plane as we were disembarking so maybe that was the issue.

Leg space was not enough. The meal was not satisfactory.

It was a short haul trip, so food and entertainment weren’t a big issue

The plane seemed very dated. The entertainment was very limited. There was a school group on our flight and the crew seemed bothered by them. They were not overly friendly or welcoming.

Ok, but no entertainment. Left late, but made up most of the time.

May be it is not an ITA issue, but the bags took long time to go out.

Good. But there food was poor quality and 95% of movies didn't have English subtitles

I thought they had rebranded themselves in every aspect but it was quite the opposite. The food was terrible the service was sub-par. Overall it was not a good experience.

Service from staff was poor, food choices were limited. Air plane was not clean or hygienic and seemed like not cleaned for days. Seats were uncomfortable.

service from stAff was barely there , food choices were limited. AirPlane was not clean and seemed like it was not cleaned for days.. Seats were very uncomfortable.

I paid for premium seats and the last minute they changed the aircraft for a bigger one, they bumped me to another seat which was NOT at all comfortable for an 11 hour flight, will fight for a refund!!

The landing was catastrophic. I was very scared. I thought it were my last lminues. Pilotes should be more experienced
