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.

It is a modern tragedy that any airline expects you to travel for 14 hours in such discomfort and that the only way to add comfort is exorbitant prices. I was in pain by the time we landed. Shameful.

Original plane sidelined. Had to wait an hour for replacement.

Crew was very cooperative and professional. Passenger's first checked in bag should be free.

No real agent onsite helping you for missing luggage there. Not like the other airline next to UA desk, they have staff attending in their desk assisting answer/helping luggage issue, even after midnight.

Horrible, the flights kept delaying, so it is obvious that we won't be able to make it to the next connection. No easier/real agent on site to help you figure this out. UA agent on other counters refuse to assist you and direct us to use the QR code/call customer service. So inefficient and poor. While technology seems convenient, but it's not the best interest/experience for customers need help while there is active issue need assistance.

They have trouble to keep their flights in schedule. Seems not having enough staff to provide appropriate customer service. Lacking real agents on site to help customers. Have to use QR code/web site/call to be able to talk to real person can help you - and you may have to punch though series of options first, then hold until someone assist you. Similar for baggage claim, no real agent onsite helping if you missing luggage, not like other airline next to UA desk having staff there even after midnight to assist customers.

United is my favorite and I always try to fly United. I feel like this crew didn’t mesh well together.

Our flight was delayed three times. It took us 17 hours to get home.

The flight crew was fantastic. The flight attendants were incredibly considerate, kind and attentive.

After the morning frenzy of 35 min wait through CLT security at 4;30 AM, it was nice to have a smooth pleasant boarding experience. This 6:30 AM flight was not full. We were able to get seated swiftly and took off promptly. Nice touch they distributed the old fashioned headsets with 8 mm jacks. Snacks were decent and arrival was uneventful.

Terrible. Missed our flight to Newark as well as our flight to London. Complete disaster

The flight was wondering, especially the special assistance from airplane to airplane!

The flight was wonderful, especially the special assistance from airplane to airplane!

They canceled our flight last minute and we had to get another flight with twice the cost

Captain waited 45 minutes for late passengers boarding from Washington DC to Munich which was nice for them but caused our luggage to miss boarding our connection on to Bucharest. We then did not receive our luggage for about 48 hours after landing which was very inconvenient for our travel.

The worst experience of my life and I have been flying for 33 years

We were very upset when we checked in for our flight to be charged 208,00 euro for luggage fees when the site clearly states we are authorized one checked bag each and one carry-on. We have never experienced anything like this with Lufthansa and are very disappointed. We should be reimbursed this erroneous charge. I can forward all receipts once I am able to scan the them.

Poor, we had 1 hour to grab our checked luggage, go through customs, recheck bags and run across terminals to make our United flight. Poorly planned connections.

Check in in Albuquerque was awful. The people were great but they were over loaded. The procedures were terrible. We got through fine but it took 90+ minutes.

Crew was very nice and helpful. It was a good flight experience.

A better organized line of passengers at the boarding gate. Quite disorganized, with multiple queues of economy class passengers

AMS FCO in their full flat business. Amazing sear and food experience.

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.

Every host and pilot were very professional. My next flight would be upgraded from economy to the next group.

I asked for a window seat and when I got on the plane 24A did not have a window so was very not happy, but good and entertainment was good and the staff was very good, so the only complaint was the seating.

Flights were actually with Aer Lingus outward and American Airlines & Aer Lingus on the return journey. Outward flight with Aer Lingus was good but the return flight with them was not so good as our seats were in a poor condition (15A & 15C) and looked like they needed replacing! The American Airlines flight from Miami to JFK New York was good and the seats were very comfortable and spacious (32D & 32E)

Awful. Flight delayed and we missed our long flight to Rome. It has been a nightmare and we have still not arrived. It was NOT a weather delay, just poor planning by AA

My seat was in a good row. In our section it was the first row. But it was difficult tooperate seat entertainment features > table, screen, even though I often fly.

Boarding was as fast and efficient as possible. The flight crew were amazing and extremely friendly. We enjoyed our flight.

There was nothing to like besides the crew. The comfort of the airplane was poor (seat did not work properly and it was not comfortable). The “entertainment” system did not work! On a flight that last nearly eight hours, (which is advertised as having excellent entertainment options), that is unacceptable! Passengers should have been given free WiFi for the flight. The food served on the flight was below school lunch grade food. (With one exception, the ice cream snack). The chicken entree was tough and nearly impossible to cut and eat. The “pizza” served later in the flight was worse. The chicken pizza had a dry crust and the “toppings” were equally not enjoyable. The amount of chicken and cheese were almost non existent. Overall not a flight we would want to repeat!!

There was a problem in the luggage because there were not porters

2-1/2 hours on tarmac after arrival to DFW, lost connection to London, 3 hours wait for customer assistance, stayed on our own account in DFW, no replacement flight for 5 days, had to cancel the entire travel and return to Monterrey today.

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.
