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.

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

Our flight to Zurich was delayed by almost 3 hours, so we missed our next flight. There was no indication it would be delayed this much. We were told the gate had changed and then it apparently took over 2 hours to load the "catering" on the plane. We were not compensated in any way for the trouble.

Rated entertainment as Mediocre as there were major problems with the Infotainment system that took probably a half hour for them to fix.

Your crew could maybe answer the call bell at least one of the times I pressed it. I pressed it first time with 2.5 hours left in our flight bc my partner was hungry and wanted a sandwich. We finally got the sandwich with 40 mins left in the flight.

Half the bathrooms assigned to economy were out of action

Delta crushed it. Flight attendant in first was attentive and just never stopped. Honestly one of the best domestic flights I’ve been on.

Quick and efficient as always. Air France managed to loose and damage my luggage that never made it onto my KLM flight.

The food from Lagos to Amsterdam was was very poor compared to AMS-YYZ

The flight was delayed for 2 hrs. Because they didn’t have a crew to fly. And it is not a first time for klm to do that. Last time they cancelled my filght and rebooked me 3 days later. Not reliable airline

Booked connecting flights with KlM. My serving flight was the furthest part of the airport. On arrival in Zurich. My two cases arrived but only one carry on belong to my son. His three suitcase didn't arrive. After enquiring we discovered they were still in Amsterdam. We landed at 11.12. We eventually left the airport just after one.

no issues at all... Kudos to the food. This time was really really good

Overall a good experience. We were disappointed when we had to check our carry on due to the plane being full. KLM hadn’t notified us and we had valuable items in the carry on but they still made us check it. Some of the food was great and some was mediocre. Crew is really kind and funny.

I travel frequently. The flight was late again... KLM should really try and be on time

The flight itself it was great nice food the crew were very nice and helpful, Checking in from Birmingham wasn't great long queues for bag dropped, And I had my hand luggage case taken away from me even though I requested to have it with me as I had breakables items. I was told I can not because of the length of the flight with no explanation at all no options was given for me to take my fragile items out of my case it was taken away with hold buggage I find the staff member who was checking me in very unpleasant !! Can we please be advise if the rules have changed about the the carry on hand luggage it will be easier to be advise on booking your tickect if we not allowed to take the hand luggage with me. Overall I had a good flight .

The plane was clean and the staff was friendly. Food and drinks as expected on international flights. The entertainment system was old style, with a pullout controller, and selections not as extensive as on other flights.

The food quality is poor. The staff are very friendly and accommodating. The entertainment program was limited. I experienced a delay of 30 minutes due to two issues. Passenger luggage had to be removed and there was a technical issue with the stairs not detaching from the aircraft. The pilot managed to compensate and we arrived only 15 minutes later. The luggage at Dubai airport was very slow. I waited over an hour.

I had a great flight. Everything went smoothly and the flight arrived early.

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!

They cancelled two flight and got us onto another airline, which was also delayed.

Nothing, terrible travel experience due to weather and maintenance delays and was left stranded in Austin.

Missed connection from Philadelphia to London because flight from DC was seriously delayed. Was re-routed the next day (had to pay for hotel) to Zurich and was given a main cabin middle seat while I had paid for premium. Great job AA!!!

My husband and I pre-ordered our food, but they did not have my husband’s order, and my cheese plate was very average. I asked for a blanket and was told they don’t carry blankets on domestic routs. The flight was on time and smooth!

28 hour delay at Fort Worth/Dallas airport, part due to weather which was unavoidable, but various other reasons - no pilot, no fa, mechanical problem, plane too small, too big, crew out of flying time, seat configuration problems.... endless and hourly updates with a different excuse. Finally told us about 3.00 am, that the flight was delayed to hours later.

Experience was bad. 3.5 hour delay for a 2.5 hour trip. There was no r Transparency about the reason for the delay and it was done 30 mins at a time.

Original flight delayed several times and finally canceled at 2:30 in the morning. Staff at the gate was not very helpful in resolving problems or communicating why there were delays. I spent 34 hours at the airport before I could leave, they couldn't book me on another early flight even after canceling my original flight. Next flight available after my original flight was canceled was 22 hours later. I will never fly American Airlines again.

very very tight seats unfriendly crew who do not seem to care about the comfort of their passengers and do not know how to smile poor ground staff support at LHR and PHX

The boarding process and flight were great. However, I waited about 40 minutes for my luggage. It did not come up on the designated belt. Instead, everyone’s bags were on a cart. Not sure what the issue was, but we were not informed until another passenger went looking for her bags and found them.

There were delays on both ends. It made it less than excellent. This plane was great though

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!!

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
