Flight was late and crew were unwilling to help with information on connections. Call light had been on for 61 minutes without tesponse.

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!

The plane was so hot upon boarding. Their boarding process was so unnecessarily long. Service was subpar.

Everything from the price to online checkin and the flight being on time to the crew and food was very good. The comfort level is fine--the seats are very close to each other in Economy. But I guess you get what you pay for.

The Zurich airport is a disaster with to small trains running between the terminals, the trains was overfilled (not good in Corona times). It was no directions in the airport with proper lines so you did not know if you ere standing in the right line. They checked your passport 3 times in the airport = a lot of standing in line. Service on the plane could be a lot better, The cabin crew could have offer more to drink (water, coffee, tea), the food sucked.

Flight was delayed for 4 hours and they misplaced my luggage too. Appalling.

Horrible experience. I was apparently picked at random for a security screening - that was the most demeaning experience I have had in my life with a guy poking and prodding and having me take off my shoes, move up my pants so he could swab my legs - telling me I couldn't bring more than some quantity of cookies - I had 3 boxes of cookies in my luggage. In the end he did let me keep them but that was really uncalled for. Harrassment in the name of security.

Everything was on time and efficient - expected from a Swiss crew. But the entertainment system was pretty bad - the display was old. Food was pretty bad and a couple of times they started serving drinks and then just skipped past my row (and likely several others)

They went out of their way. It was very clean and friendly.

Liked being hydrated. Carryon weight was limited for cold weather clothes that are heavy... could test to improve if possible.

All good- I love BA and the professionalism of the crew and pilots.

Great flight- smooth, nice crew, nice clean aircraft, departed a little late but arrived 10 early.

It was listed on my ticket as Finnair but there was no indication that the flight was Finnair. In fact the number was even different. There were no employees there until exactly 2 hours before so we had to wait in line at Iberia and hope

Sorting on line would have been appreciated Onward information on flights missed No ability to get seating arranged before we got to gate Very unfriendly at gate

The flight was Finnair but there was no indications anywhere that the checkin was for Finnair also. There was no one to ask. I think at a minimum they should list the code shares so people don’t stand in the wrong line for an hour.

Flight ok, but me and other two passengers didn’t have connection with the entertainment in our seats. So, no movies, no games, no music… for 9 hours. The crew just told us that there’s nothing they can do but I noticed during the flight that there were empty seats, so they could have offered to us to change seats. Customer service could be better.

Had a nice flight to London on BA will fly with them again in the future

Finnair cancelled my flight 12 hours prior to leaving for Helsinki. They stated there were mechanical problems. I had to scurry around to find a new flight that would meet my needs for arrival in Helsinki. Luckily I was able to find alternate transportation through Lufthansa/United.

I’m very disappointed, to fly into an airplane for 10 straight hours, and not having a TV even though when I put the ticket I was told that I will have entertainment for the TV. Very disappointed.

Helpful steward. Allowed me to move to some empty seats and I was able to get some sleep. He also had milk for my tea. Americans don’t realise that cream or half and half ruin tea.

More facilities to transport to the gates......felt too much walking distance

Just happy I flew Qatar Airways awesome no wonder they are #1 in the world right now! The food was just delicious, very courteous, professional crew.

It was good no problems made it on time for the next flight overseas!

It was a really long flight from Doha to Philadelphia and it was overall a good one. The one area that I would comment on is that there is a lot of single-use plastic and disposables in the meal service for American Airlines. It would be great to see more circular options in the meal service to reduce the amount of waste.

Suddenly Flight has been change by Qatar and there’s no information is there of us from Bom to Doha and counter person is behaving like Qatar owner next I will not buy Qatar and I will not suggest anyone to fly in Qatar

The crew was fantastic and the over flight was perfect as well.

They shld provide food. Between food they are giving 10 hours gap which is toooo much

The crew was great and the food and liquor offerings were good. Seats were a bit cramped. Flight arrived early at destination. That's a plus.

All over with Qatar airlines my experience was really bad due to delays and then putting me on different airlines and after 8 hours of wait I had to listen to their is no plane to fly for another 24 hours. Wore experience ever.

I had already opted for Vegan food before 2 months yet they say we have no record for it,

It was freezing in the airplane. Everyone was wearing everything they had with them. The crew acknowledged it was cold, but did nothing about it

The flight attendants were superb and the service was outstanding. Some passengers with small children were very rude and inconsiderate, kids were constantly crying and some were running around the aisle unsupervised.

Terrible. There was a rattling noise the whole flight. The internet didn't work after I paid. Boarding is very disorganized.

Horrible flight attendant in back of economy that screamed at me, have already reported to United. Horrible food - for Gluten free, why would you assume the person is vegetarian? I was served some kind of horrible curry bean paste and multiple cold rolls and soggy vegetables with no seasoning... um no!

The crew member put her luggage and boxes behind my seat so I was able to recline while the passenger in front of me did for 8 hours. My knees were forced against the seat for hours :(. Dude sitting next to me hasn't showered in weeks so I almost threw up.

Sorry my last review for prg to fra was for this flight. My prg to fra flight was fine but my second flight back to Washington DC was with a slow awful crew who wouldn’t come in a timely manner to take trash and take trash before serving coffee tea and was shoving other people’s bottles of water on me when we were not traveling together

Lufthansa was amazing. Definitely upgrade your seat if you can swing it - they take very good care of their passengers. Customs in DC is nothing short of a nightmare though. Stood in line waiting to go back through security for 30 minutes, had to RUN through and across two terminals to make my connection and only had 5 minutes to spare. Terrible. Very very poor coordination by the airport staff and CBP.

I was ver pleased with the service all the way through

I always try to book flights that don’t charge for baggage. Yet I was charged $75 for this flight.

Trouble keeps changing the time and I was booked different flight without knowing it was bad experience

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.

Spending 10 hours on a flight with no video or wifi access due to issues per stewardess was not enjoyable nor acceptable. Will follow up directly with the airline as well

I really did not like being ordered to pull my shade down by the attendants. One of them was very rude to me about it, standing there until I closed it like I was a child brusquely reaching across me to close an adjoining one. They claim it was so people who wanted to could sleep. It’s a 10:30am flight not a red eye. Closing your shade or leaving it up for natural light should be a choice. Ruined my flight!

My baggage did not arrived with me. Took 3 days to get it after so may calls and follow up

The crew was very attentive and kept busy serving a variety of treats!

Terrible. Flight was 3 hours delayed and I missed my other flight to my final destination

Offered vegetable curry when it was actually tofu which I don’t care for.

The flight was good the crew excellent…but take off delayed three hours!!!

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.

perhaps eye contact with the cabin crew, instead of abruptness and an impatience to serve.
