Food seats were good Flight was delayed for over an hour, missed connecting flight, lot automatically rescheduled us to a new flight which was good but lost approximately 4 hours. Not a good way to start a vacation.

Stuck on a plane for 6 hours due to a technical or mechanical issue.
Boarding was a madhouse. Airport staff was completely disinterested in communicating about the delays. Never again.
The seats are very narrow. Communication regarding bids for better seating could be better
During the flight, the fleas biting me in the plane.
The crew and flight were amazing . However , my bag’s locker got broken and no refund provided . Everything else was amazing except this bad incident that ruined my experience
The seats are small and the movie selection was disappointing. However, the food was excellent and the cabin crew was attentive and kind.
Plane is super outdated, seats not that comfortable for business class. Lounge also out dated. They need to catch up to 2024. Don’t think I’d ever fly again.
Aircraft was new. Food so so, especially vegetarian was very disappointing.
Boeng Dreamliner has so tiny seats, so even medium and smaller size people have not enough room to fill comfortable..
Entertainment system is okay, flight attendants were ok. Leg space very narrow, I couldn’t get what I wanted to eat, dinner nor breakfast.
Excellent experience with business class area. Staff was attentive and food was amazing. Only one bathroom for business class which was logistically difficult for the staff while preparing meals. Need to offer fluids with meals. I did not get enough water to drink. But overall I rate it 5 star.
As a big guy the seats are way too small for me. Would prefer more comfortable seats on these long haul flights.
The staff at IST airport could have been more helpful. Too much wasted time and the plane from IST to KHI was just horrible. The plane was not clean and smelled bad!
This is my 2nd time with the Turkish airline. Would definitely recommend. In stability we connected to Indiago would not recommend, very cramped seating. No inflight entertainment..service was inferior.
Vegan food tasted good. Restroom could be kept cleaner. Seat tray table was a bit tilted so food tray kept sliding down a bit. Flight crew can be a little more friendly, caring and approachable. Their faces lacked smiles and tone was stern.
Flight was delayed then we had to redirect for medical emergency during which time we had no information on what is the plan. The connecting flight was also delayed.
Awful seats, poor air circulation. Smelled like poop for 3-5 mins after someone used the bathroom. Child screaming for 13 hours
We are thankful for the useful gifts provided by the airline.The entertainment and crew were also very good
Quality of service on board was very inconsistent. FA service primarily seemed robotic and they barely engaged with passengers
Better management of the boarding process. Is there any way you could forward all the window seats first? That's the Way Reno Air used to do it, and they had the fastest boarding in the industry!
overall a very good travel experience - left on time, arrived early. Mostly a smooth flight. Polaris seats were excellent, very good service and nice food with options.
Flight was over two hours late, but they notified us early in the morning. They ended up changing planes the food on board that was extremely mediocre and we were in premier class.
Food was very bad Crew was not so welcoming. Chairs was so uncomfortable
The business class had to wait to board last. Unacceptable
The air hostess was excellent. I have taken so many flight domestic and international, this is the first time the air hostess was so caring. She was a delight
We paid extra to check our bags ($90*2=$180) but our luggage remained in Frankfurt. VERY DISAPPOINTED as we were promised that our luggage would go to our destination. We had to pay 90€ to take a taxi back to the airport in Split the next day to get our bags so we would not miss our next step on our trip. We think we should be reimbursed for our checked bags. How can we coordinate this?
This was an auto-rebook due to being delayed from an earlier UA connecting flight. The boarding was fine, but they sat me in a middle seat when my original booking was a window seat. Overall, the flight was fine as it still got me to my final destination.
Sitting in coach even in the larger leg space is extremely uncomfortable and the staff pay no attention.
The pilot was late so we didn’t take off til almost 2 hours late.
Our seats were not together - one on upstairs business class, the other nicer downstairs business class. Terrible!! A very nice agent worked hard with other passengers & got us upstairs together. Not ideal experience. Check in agent should have caught that! Asked about upgrade to first class for additional $2500 each. Refused upgrade saying we upgraded once already. We booked on business class to begin with so we’re NOT happy!!
Great. Only issue…the cabin was kept as warm as a sauna.
Lost our luggage, now two days and four $30 each taxi trips to airport and long lines in taxi queue because Lufthansa didn’t get it right, by not recognizing new delays between flights caused byEU new lengthy crossing requirements for non EU travelers, so luggage lost because traditionally methodical and orderly Germans not paying attention.
They set someone on our assigned seats and we ended up finding seats for ourselves to ensure the family sits together.
Flight attendants were fine, seats a bit hard but I use a cushion for extra support. The only issue was it was a bit too cool and I needed to ask for and received and extra blanket. I survived!!!
Food choices limited & not enticing Seats quite uncomfortable & difficult to control
Boarding was disorganized. The door to one to the toilets wouldn’t lock. The plane was shockingly cramped, and clearly used for domestic flights due to the menus for items to sell domestic travelers. United should be ashamed of its small seats, tiny unclean toilets, and money grubbing stance toward services, compared to Lufthansa, Emirates, and most international carriers United is awful.
Service and food were excellent. Incredibly friendly and competent staff. Flight was delayed over and hour and I had to run between terminals to get my connecting flight.
Everything was really great just The aircraft was too old and sounded it will break during takeoff
Extremely pleased with the crew. Best flight attendants ever! Very friendly, genuinely caring and attentive.
I washed attendant for assistance and she never got back to me. I asked her a second time and she said she would check. She never did. The flight was over an hour late taking off No food service was offered despite over 4 hours on the flight
Boarding from the SFO lounge is a big improvement. Although the first class dining room inside the lounge is becoming very crowded.
Boarding was orderly, pilot and flight attendants were nice, entertainment options were good, and low sodium meals were quite tasty.
Flight delayed, connection was not at gate listed and so missed, staff were rude at Heathrow, phone tree stupid and difficult, took me 21 actual hours to reach my destination. Almost lost my hotel reservation after walking in a strange city alone after midnight because they would not put me up in a hotel at sfo or heathrow. I will never fly BA again and will tell all people and Instagram followers never to fly BA.
Wish the food and overall service was better. They treat Business class passengers same as economy
Loved the boarding option from Business class lounge, experience on flight was excellent, plenty of good food choices
Check in was was and the agent was very friendly and helpful The lounge was nice...boarding was straight from the lounge Everything worked at our seats, and video entertainment was good ..food was mediocre
Airlines have to stop assuming passengers bring entertainment. Provide it like you used to in business class and above!! N
Crying baby the ENTIRE flight. Not your fault, but I paid 2700 for a premium economy ticket and it wasn't worth it. should have just stuck with coach. flight attendants very mediocre - minimal effort. Plane didn't seem very clean. Didn't have any cleansing wipes - most airlines give you this when you board. Flat screen scrolling didn't work. Toiletry case a joke - why bother at all?
Enjoyable flight, helpful crew everything was organized to accommodate passengers.
