Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

It was pretty good I was worried with the short Layover that I might not catch my connection but the gate was there

It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

Friendly flight attendants. Comfort plus seats were very comfortable and had lots of leg room. 10A and 10 B.

I've flown many many times on Northwest and then Delta. The crew on this flight were absolutely the best I've had the pleasure of being looked after by.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Awful. Flight was continuously getting delayed and gates kept changing without any reason. Flight was delayed for more then 3 hours

Paid premium for Delta only to be on safe but tired old 767 with ancient cabin in mediocre condition. Poor wifi and horrible inflight entertainment. Hardly a premium experience. Should have flown SW and had fun flight crew and no pretense

Besides the flight cancellation, everything else was prefect. Kudos to Malaysian Airlines.

Operated by American Airlines. Very chaotic and the crew was bit rough responding any enquiries. Restricted leg space.. Qatar would have been better

No towels or tissue and chocolate and mint provided before arrival

Qatar airways from Doha to guangzhau was excellent big bird Boeing 777 more room and smoothly flight, I Love it

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

They made us deliberate waste time by holding our passports and boarding passes making us miss the flight

The made us waiting and held our passports and boarding pass making us miss our flights

Not impressed. Only allowed one carry on on such a long flight.

The flight was good but my neighbor had the vent open full power for the whole flight and because the air was blowing from the side instead of from the top and I got very cold and ended up with a sore throat.

Bad experience with the delay n long wait time for connecting flight after missing the connection flight from Doha.

The check in was horrible. I stood in line for 1 hour to check in with an Air France ticket. Then I was told I had to go to Delta counter onstead to check in instead. It made no sense.

They wanted to close counter although they did not provide the wheelchair requested which ended by going alone to transit security and lost long time and they did not want to wait .

Good aorcraft 777 but Worst food ever Breakfast was a bû’with matonnaise… Staff was nice but invisible most of the flight

Business class in the second leg - CDG-EVN was a disaster.

Everything went smoothly with Air France. There was a delay in departure which seemed to relate to the immigration services being short staffed.

worst experience ever i choose my seat in advance and also have my seat selected in my boarding and the they told me that my seat has been changed without notify me

No birding was given for next trip on same carrier, food was very moderate.

We transited through Chad and what was supposed to be a 1hr 20 minutes transit time lasted over 4hrs. We didn't get regular updates until we complained. After a 10hr flight from Paris no form of refreshment given and finally arrived Abuja over 6hrs later and none of my bags came

The line at boarding was not well organized and managed

A couple of minor delays in boarding but very professional and efficient staff.

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.

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.

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!!

Economy class has no legroom so if you have the money worth to upgrade! Food was absolutely horrible! The crew was super nice!!!!!

The flight was provided by Aer Lingus and our seats were in a poor condition (15A & 15C). They looked like they needed repairing/replacing and were uncomfortable for such a long flight. Also the arm rests on Aer Lingus planes do not lift more than around 45 degrees, instead of the usual 90 degrees upright, meaning you cannot maximum the space between you & your travel companion so as to be more comfortable for such a long flight.

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. Delay, lost vacation time and travel time now more than 24h

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

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

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.
