I arrived 59 minutes before the flight in Tampa due to Massive traffic jam and the flight was closed and I was told that I’d simply have to “book a new ticket on line myself and the gate agents couldn’t help me”. Even though the flight was delayed over 30 minutes, (leaving one hour and 29 minutes before departure, they refused to assist in any way explaining that it’s automatic and there can be no exceptions. Horrible experience due to poor management at gate. I fly this option 2-3 times a year and have a good experience with the cabin crew etc. But, Tampa agents are not trained or allowed customer service. I once was a gate agent for USAir, I know times have changed, but forcing me to purchase a new ticket and complete indifference and inconvenience. No thanks

Crew was super courteous and helpful. Food quality was not so good. Most of the movies were old.

Crew members were good. Seats were packed and too tight .

Carry on luggage size for economy passengers significantly smaller than other airlines, so nearly all ecomy passengers had their bags taken and checked.

Had a short layover in Zurich, luggage marked expedite and short layover but still didn’t get luggage when arrived in Split until 3 days later even though husband got his.

On time flight, I requested wheelchair in Zurich , when I arrived they were no where to be found, I had one hour between flights I had to walk with great difficulty.

We had issues with upgrading our seats. The flight itself was fine.

Horrible experience. They "GAME" with seats they decided to play where you can`t select or get seat during check-in without paying and then forcing you to stay long line at the Customer Service at the gate to get a boarding ticket with seat assigned is pathetic. Will never fly with United again!

So terrible. They would not rebook me for a flight until 2 days. I had to spend so much money to get my own flight. They were rude and not helpful.

Overall a good experience, the flight was on time, the crew very attentive and friendly. However the seats are too cramped, there is no space, and as soon as the person in front reclines the seat, it's literally in your face.

Overnight flight in the old style Business class, but still very good.

I was in business class, without the business class amenities. Large seat with lots of legroom, but no TV or bed. Food was okay, but I did enjoy the Turkish red wine.

Excellent service and comfort from the moment you check in. Flight crew is hyper focused on making passengers comfortable and at ease. It’s like a flying hotel!

Only chicken as a meat dish through out the flight

Nothing really was great as such. Seen other no name airlines perform better.

Quality of service on board was very inconsistent. FA service primarily seemed robotic and they barely engaged with passengers

I’m unclear why I had to pay extra for assigned seats as Turkish airlines did not honor the seating. We were placed across the aisle from each other on TK 34, and were seated behind one another on TK 694. Because my name was misspelled on e-ticket (Klawiter, instead of Klawitter) I could not log onto website to get the connection gate number in Istanbul. The monitors in the airport were a jumbled mess 1/2 Arabic and 1/2 English.

On line check in needs a lot of improvement. I tried and gave up.

Food not good, flight attendants not the best, not accommodating very ruff

the female flight attendant was racist towards me. I could tell she treated the two other passengers next to me with more softness.

Well....let's start from the point that I had to stay in airport for 12 hours instead of 2 that was scheduled. Poor company and even worst customer service. Never again....

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.

We liked the fully reclinable seats. Had center seats, so it was difficult to talk to spouse. Crew was great

Aisle chair was good and liked the foot bar preventing you from putting your foot in the isle, The breakfast on this international flight to Zurich was horrible (Europeans, specially, used to good food) may make this a dealbreaker for booking with United Airlines again. I agreed with my Spanish fellow passenger.

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

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.

The flight was delayed almost 2 hours. Bad customer service etc. I will never fly Luthansa. Ever!!!

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

Fine. Though no food or entertainment so the survey needs to be updated with those options.

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.

Boston Logan is a crummy airport - signage is terrible or lacking in areas. Boarding seemed to be a free for all and with all the different airlines speaking, you couldn't tell who was supposed to be where and when. Plain and simple, airlines should board from the back of the plane to the front. Also someone was sitting in my seat. By the time that was figured out, I had to place my overhead behind me which made de-planing more difficult. Logan is not Lufthansa's fault so that is not on them, Boarding is on them! Still, overall it was a Good Experience flying with Lufthansa. This is not my first flight with them...

Overall, the flight was comfortable without any serious issues. Transit through Frankfurt airport was a little confusing, but not too difficult if you follow the signs

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

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

Staff disappeared after dinner service until breakfast, no help with beds, no help running to our gate to catch connection cause flight was late, our luggage didn’t make it, took over 24 hours to get luggage to hotel, no compensation!!

Everything was good except food. I believe there is room for improvement

Houston to Porto flight delayed landing made us miss our connection. Tried to get on standby for the next flight and even though the lady knew we wouldn’t be able to get on it and she sent us down there. We sat there three hours and then we’re told there’s no way you’re getting on this flight. So we had to go to customer service and ended up having to spend the night in Frankfurt and missed a whole day of our vacation in Porto

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

Very bed boarding, there was overbooked and make a lot of problems and noises

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

On my way from Chicago to London, I was seated next to a quite heavy passenger. I could barely move. BA should have ensured that overweight customers are placed in comfortable seats and not to penalize also other passengers because BA is not willing to accommodate these passengers and their needs. No respect at all.

The flight as far as timings go was excellent. Unfortunately we ended up sat with someone on a night flight who had been drinking alcohol before boarding and BA staff were happily serving him more alcohol. He was very drunk which made our flight uncomfortable and awkward. My partner had this person lying on him whilst asleep. Alcohol should be served minimally. If there had been an emergency this person would not have been in a fit state to act accordingly.

First time flying with BA and I will do it again. Staff at airport and on board were very nice and helpful

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

Wonderful service and very comfy in the bulkhead in Economy Plus! Delicious food.

The BA team at Sky Harbor is deplorable, full of unnecessary attitude and poor communication. It seems like every member of the team was looking at another to solve the problem, instead of taking agency to do so themselves. I saw no less than 6 altercations with the same gate agent where he threatened to revoke the passengers boarding pass for asking a wildly reasonable question, something as simple as where the cue to board was. I’ve complained to BA before but it seems this isn’t an issue for them, which is very disappointing

Boarding poor in London,ok in Chicago. Don’t like Heatrow/terminal5

It was very good. We got a late start by about an hour and a half. However I worked rather have that than crash. It was purely mechanical. They had our tickets ready when we came off the plane in London for the next leg. The only mishap was when we got to Lisbon my husbands luggage made or bit mine didn't. All was not lost because I did finally get it 2 days later. I was really pleased that they c made the effort.
