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.

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.

Backpack should NOT allowed put in the flight bin , only put it under the seat. I can't find space put my carry on luggage!!! and I pay for it ! that was very bad experience

Fantastic. Smooth boarding with an infant. Never experienced it with any other carriers.

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

AA1537 the AC was not working properly. It was very hot and uncomfortable.

So uncomfortable to sit in the tiny space on a long, international. Food was rough. Please, less white flour and processed food.

Worst experience flying American Airlines. I fly with them often, so I was super disappointed in the service I received at gate 30 in LGA on May 24, mid-day. The flight was delayed twice. I was patiently waiting in the American Airlines lounge when I received the notice on my app that the plane was boarding 45 minutes before its newly re-scheduled take off of 4 pm (from the orginal 1:45 pm then 3:00 pm). It took me 5 min to travel from the lounge to the gate and when I arrived there at 3:20 flight gate attendant told me the flight had closed and that they announced for passengers multiple times. I showed them the notification on my app and they were really rude and unempathetic. The person who rescheduled my flight at customer service wasn't any happier but was at least helpful in getting me on the next flight.

Flight was 1/2 hour delayed leaving Phoenix. Otherwise it was an average flight. Flight crew on this trip was very nice.

Our flight was delayed 2.5 hrs due to plane being too hot! After 1.5 hrs, airline decided to use another plane but had to wait for gate, baggage transfer & beverage transfer. Anyone could tell after first half hour that another plane was required and although did not affect us many would miss connecting flights at Heathrow. I have found the stewards are not the friendliest in the industry and the food is questionable, even as I like airplane food normally, the best of the 2 flights was the yogurt & granola for breakfast.

Everything was great except for the wifi was junk. Crew was super friendly and helpful

Was lucky to have a employee at the AA checkin counter that had compassion and understood they ordeal that we went through with our original flight being diverted, needing to stay in the aircraft and then flying to the original destination; adding hours to the trip and forcing us to miss our connection and our rebooked connection. She was able to get up on standby on the highest priority on the next flight to the closest airport we need to be at and it all worked out despite being many hours late.

Delayed so that missed connecting flight. Connecting flight was also delayed on the tarmac but they closed the gate before the rescheduled time.

Unable to initiate refund/reschedule the ticket #worst experience #lost 900$

Flight was delayed for almost 3 hours. Communication of gate change was poor. Email and screen said one gate and it was a different gate from that. Gate changed first to 64 B and then to 64 C. Originally it was 68B. 64C was not communicated properly!

This was a red eye return, so I doubt there would be anyway to make it better. Other than adding beds.

Direct nonstop flight was great. Flight was delayed and the crew announced a 2h delay on the sound system. 30 min or so later I hear my name on the sound system for immediate board. Several other passangers were late too. Reason: The crew incorrectly announced a 2h delay when in reality they meant a new boarding time at 2pm.

Plenty of room in the exit row. Sat on the plane an hour before taking off.☹️ Landed late and had to wait for gate availability.

Flight was on time early arrival better entertainment good staff.everything was excellent

Delayed leaving. On arrival we were taken to the airstrip and had to get off onto an over crowed bus, not all that passengers fit. Drove around the airport for 20 + minutes. Taken off the bus told to go upstairs 3 flights then all the passengers had to walk a mile or more , those of us old there was no one to direct us to were to go. I asked several people with no answers. Once I got to baggage claim my bags were not on the right bag claim. Once again asked for help and finally someone found my bags on a different carasel. Very frustrating.

Excellent host on board. Not so friendly check-in staff. Older plane with no food or entertainment due to short flight. Friendly captain and crew.

I don’t think there was entertainment? No mention of it. It was a good flight. Only complaint was my seat cushion was not attached and kept slipping.

They canceled the flight on us very close to the flight date .

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.

Leg space was not enough. The meal was not satisfactory.

Liked that my American Airlines status seamlessly transferred to BA so luggage check was free. Flights were on time, boarding quick. Wish they didn’t assign connecting gate so late at Heathrow.

The entire process was flawless and as expected flying first class. The only thing that I have a complaint on...when first boarding, the plane was EXTREMELY cold; then when we were trying to sleep, it was way too hot - just better regulating (especially trying to sleep) would have made it perfect.

- OK plane. Basic accommodations. OK food. The digital window shade wasn't working.
