The boarding process was efficient and quick. The seats were comfortable. The food was good. The service was excellent. We had a lovely flight from Seattle on Korean air

Flight crew was fantastic. The aircraft was meticulously cleaned at all times. The crew was continuously checking to see if the passengers were ok.

They were trying to get people to check luggage because the over head compartments were full but when we boarded there were lots of empty places that people could have put the luggage.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!

This flight was a superior flight in all regards. Extremely pleasant experience.

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

Not many people, so you can lay down on two seats

Extremely uncomfortable seats with very little cushioning, unable to recline enough to sleep comfortably on this 13 hour overnight flight. My body was in pain by the end.

When we checked in at the Siem Reap Airport in Cambodia, we were only given three boarding passes and told that we would have to check in with American when we arrived in Boston. This was a source of stress for us. After we landed in Boston, we had a long passage from Terminal E to Terminal B (American Airline ticketing counter). Because the electronic ticketing kiosks for check-in would not recognize our Confirmation Code, we had to wait for an hour in a long line where only two AA reps were taking care of Special Services passengers. In many years of both business and recreational travel, I have never had this experience. I would expect more from AA being in partnership with other airlines to do a better job with this.

Our experience on the Doha to Hyderabad segment was extremely stressful due to prolonged delays and a lack of clear communication from the airline. We were traveling as a family, including children, and the uncertainty around timing and next steps caused significant distress. There was very little proactive information provided during the delay, and we were not given clear written explanations about what was happening or how long it might take. This made it difficult to manage the situation, especially while caring for children in a transit environment. In addition, one member of our party was ultimately unable to continue travel, which added to the emotional strain and disruption of the trip. Overall, the experience highlighted gaps in communication, customer care, and handling of unexpected situations. We are sharing this feedback so that future passengers, especially families, are supported with clearer communication and better assistance during irregular operations.

The seat cushions are absolutely lacking, not sure if they know the passengers are traveling for 14 hours straight, but the padding made our back and butt ache like crazy. The entertainment console had its own problems, either the headphone jack wasn't working or the power outlet via usb or ac outlet was not working. Not to mention the seat handles were not adjustable in some planes in the middle or on the aisle. Qatar/Indigo may be operating a very old fleet of planes to make as much profit as possible, but passengers may not be following them for long, should this treatment of its customers continue. Qatar/Indigo, wake up and do it right by your customers, or they may not be your customers anymore.

It would help id flight crew were not rude and showed some courtesy. They were shouting at passengers and yelling instructions as if we were school children at lunch cafeteria!!

All good. Over four hours flight if provided snacks like Qatar Airways would be better

Lobster starter in business class was not good, tough, served cold, and without butter. Movie selection was missing latest releases, did not offer older classic, high quality movies

Food was absolutely pathetic. I wasted so much food which I thought was inedible. I also loathe the inflight entertainment system which has very little content

My entire row did not have power for the full duration of a 14.5 hour flight. Could not charge any devices such as laptop or phones for the entirety of the long flight. The flight attendants tried to remedy the issue by resetting the power, but were not successful. The only other solution provided was to move me to another seat on the plane which was in the middle row. I had paid for a “preferred” seat that was a window seat. This was a downgrade being offered due to the power issue.

Nothing to complain. The staff and flight was good especially the seats which was better compared than the cloth ones on Qatar airways

United didn’t even try to hold the flight for me. They knew I had a tight connection and when I arrived at the gate less than 10 mins after final boarding the flight had already gone. The gate agent wasn’t even notified that I was on my way. She was told I wasn’t at the airport

Good quick flight on a small but comfortable plane. I'm 6'3 and had plenty of space.

The flight was delayed so we were dead tired, and after that the turbulence was horrible. I was very scared.

Wifi took a while to kick in and we had a maintenance issue that took over 40 mins at the gate in Washington before pulling back

Very good. Because of the delays with my previous flight, I missed my connection, but I was able to book another flight through the United app easily.

Was happy we finally got upgraded in 1st class. The seat getting old. The cushiness need some improvement.

Ineffective communication with United resulted in lost baggage. Their Baggage Tracing counter at MUC was shut down from 11:00-14:15 on my arrival. Undertrained, underinformed staff had me Running all over MUC to find someone to help me to no avail. Staff was rude, unhelpful, and unable to effectively use the systems they did have operational. They refused to contact United in any way or provide any accommodation or other resources while I waited for my luggage. This has destroyed my downstream itinerary. If they had even the slightest visibility I may have been able to reschedule/plan, but again, their staff provided nothing, and did nothing more than their website, which doesn’t even work on a standard phone browser. Miserable failure at all levels that weren’t associated with the operation of the aircraft.

Sat next to a one year old. She crawled all over the place and made me laugh.

The Crew and the food was the worst I ever had in Business Class. First they told us there were no space for carry on. It was plenty of space over our 2 row seats, we had to ask to let us travel with it which was accepted. They were aware that we had to run for the connection due to the previous flight delay. Have us one hour waiting for more customers and not even offer a glass of water. Then started the service and they started to serve other passengers drinks in business and did not offer any drinks until they serve our pre ordered meal and I ask for something to drink. I had to wait until they finished to serve all passengers until Inget something. The crew was the worts I ever had for Business Class in my life.

Not great experience - we were super late boarding due to issues with aircraft. Then when we finally all got onboard and seated and they started taxiing out to the runway they just stopped then turned around and went back to the airport. Apparently the crew “ran out of time” to legally fly us. They mentioned that they were about 2 minutes away from taking off. I understand the rules and safety but kinda wonder why they would have bothered boarding us in the first place? Had to go all the way back and de plane and then wait in a HUGE line to get a hotel (this is somewhere around 2:30am) finally got to hotel by Uber (no shuttle after 20min so gave up) and they ended up putting us all back on the same aircraft at 10am next morning so got about 2.5 hours sleep. They did give us. $250 credit, but it was a São Paulo Brazil flight out of Dulles. The flight and everything was fine.

The seats seems abit small and the reclining is too much, the seat in front of me came back too much and made it uncomfortable for me.

As a first time flyer with Turkish Airlines. My experience was very good due to the factor that there were to many passengers on the my first flight compared to my connecting flight. However, I know that nothing is perfect and all companies are trying to accommodate their passengers to the best way possible. I will always say, a FEW INCHES will go LONG WAY. That's something all airliners should consider, and not only the money aspect!!! A long time commitment is better than one time service! Thank you

Flight was delayed. While standing at the gate, a note appeared on the sign saying the gate had changed to a gate far away. No member of the Turkish airlines team got on the microphone to instruct passengers to go to the other gate, to ignore the chiron, etc. Finally, the message disappeared. Eventually, the flight began to board. Very slowly. More slowly than I experience with other airlines. Though Istanbul may just be slow . . . In all other ways, great flight, great entertainment (top notch movies), great service, excellent food, comfortable lie-flat seat, dimmed lights, etc.

Staff at the airport wasn't helpful or friendly. Probably the worst airport experience I have ever had, going and coming. The staff on the plane was better. Still not super friendly or personable. However, they were not rude like airport staff. They ran out of certain menu items. Maybe could have been prepared better? Overall just ok.

It was a pleasant experience. In flight entertainment could have been better

The desk crew at the LAX crew could do better. A girl named Mahesi was very abrasive and unfriendly. She needs a better customer service uproar.

It was peaceful excited We enjoyed it always Turkish peaceful excited

Istanbul to Lahore flight was less than standard for international business class cabins. Seat did not were not flat and it did not operate easily. I had to push buttons hard repeatedly to operate the seat. I was in 5A seat

IAH to Istanbul was outstanding across the board. The flight from Istanbul to Male was good, not great.

the cabin was kept too hot. couldn't sleep as a result

They forced me to check my hand luggage at the gate.

I specifically choose not to check bags to ensure I can proceed directly to ground transportation upon arrival. However, due to a recurring lack of cabin space, I was again forced to gate-check my rolling luggage after going through my luggage to take out electronics and batteries. This practice unilaterally changes the service agreement made at the time of purchase. JetBlue needs to find a better way to manage overhead space that honors the carry-on baggage allowance.

Still hasn’t left. Why are you asking how it was?

Flight was good wish there were more snacks options for such a long flight but stewardesses were very pleasant as was flight crew.

I was denied a plastic fork to eat my food and was told plastic forks are for paying customers who buy Jet Blue’s food. So I had to make a utensil out of a cup so nourish my body. Like a refugee. Because decency is dead.

I was especially impressed without efficiently the crew got passengers on and off. One of the stewards was slightly gruff, I thought. No big deal but that's what I noticed.

Absolutely horrible. Flight was delayed 4 hours and they had no clue what was going on.

Onboard functioning wide-variety entertainment on a budget and having an open pantry is nice. Seats are not comfortable but go provide plenty of legroom for a 6'2" 260lbs man.

Even though the weather made a lot of flights become cancelled Jet Blue made the flight that was supposed to leave at 9 pm and we left at 12:15 am and I was so grateful- Thanks to the Senior Jet Blue Staff who made those decisions

Worst customer service ever experienced on the planet, dirty plane, no communication, and severe delays
