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!

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.

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

They were an hour late and they didn’t have my wheelchair for me

The Flight crew didn’t serve us until about 1.5 hours into the flight because of turbulence but after it ended it was fine to move around. They served us water only and snacks and then NEVER, NOT ONE TIME came through to collect trash until right before landing about 1.5 hours later. There was absolutely no need for that. They crew was just standing around talking and visiting with each other and really never tried to see if we might want something besides water or even try to come pick up trash. This is VERY unusual for a Delta flight but it was not what I would have expected for a 4 hour flight.

The Wi-Fi was unavailable on this flight for some reason.

This was a Lufthansa flight, not United. The CSA at the counter, Ashley, was not only incompetent, but quite rude. Me and two other PAX waited over 7 minutes standing in front of her and another CSA and they ignored us. We joked that we must have accidently taken invisibility pills. She could have at least said "I'll be with you in a moment, I'm currently....". I could go on about how rude she and the other CSAs were (whispering, not communicating with me, blaming the situation on others, etc.). She would not work for me. Then, she gave me literally the worst seat on the plane. the worst. My seat kept getting bumped (rammed twice by the crew with their carts and about every 5 minutes by someone using the bathroom), listening to the bathroom all night, crowded seat, etc.

We ended up with seats in the very back. So they did not recline. Have no idea why, we reserved and checked in very early. The isles were very narrow and the seats had very little leg room. But they did give us water, and a snack.

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

Positive: Entertainment via phone on the short was great and my first time. Good food and wine and head phones for free. Negative: Seat hardly reclined on the long flight. Breakfast was an egg with a bun. No egg choices and rather have something sweet like bun/jam and Youghurt.

They did get us booked on a later flight, but it made us miss our connecting flight. So, we had to stay and another state overnight with no luggage or clothes. Because they kept our luggage at airport for next flight on the next day.

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

Crew is way too many times on the intercom re explaining the same thing

Amazing comfortable chairs great snacks super friendly staff pilots did excellent job. Smooth sailing all the way. Definitely be flying United more.

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.

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.

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.

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.
