All went well, right on time, easy boarding. We ordered the evergreens grain bowl and were surprised and pleased how adequate it was for vegan lunch! Landing was smooth and gate exit was easy

My seat and tray were filthy. Someone’s used straw was in the seat pocket and there were coffee stains and food crumbs on the tray table

There is nothing critical to complain about but I would say the snacks are pretty bad Airline staff could be aggressive the way they move through the aisles and the plane I also got hustled for a small wallet size men bag and force the consolidated with my carry on item we're talking about a wallet size bag.

The crew was very friendly. Boarding was quick and efficient.

On time, good boarding process very quick. Clean planes. Planes are tight, not much leg room ( i am only 5'8"). Some attendants are moving through aisles fiercely and pushing passengers. Got yelled for a tiny man bag that it is an extra personal tem ( size of a wallet) Wi-Fi on the plane does not work well with android phones.

I didn’t go, and can’t use a no refundable ticket.

The bathroom trash container under the sink fell out and was like that long before my flight. The plane smelled of canned fish and floor was Deteriorating

we bought Mediterranean boxes for lunch. The salami in mine had gone bad long ago, but my partner had good salami and could eat it. Could I buy assigned seats? I guess that I didn't spend enough, so sat at the back of the plane

My TSA pre check was left Off my boarding pass which was a large inconvenience.

good food and service and the seats were much better than anything comparable provided by US airlines. The entire experience was light years better than flying with a US company.

Connection through Atlanta was difficult. Mechanical issue on plane caused a two hour delay. New gate was a mile away.

No WiFi. Comfort plus should have alcohol provided, crew only offered water or tea. Who the heck wants tea?

The flight was delayed and oversold. I volunteered to give up my seat for compensation. Thinking I could get a good night's sleep instead of arriving home at 2 am. It took over an hour to get the new reservation confirmed, three different gate attendants, and two red coats. It took even longer to confirm the overnight hotel, and when I arrived, the line was 45 minutes long, with two people checking in, and at least 15 people slowly, very slowly—no food except frozen convenience food, no coupon for food from airlines. Slept, headed back to the airport, and that flight had an equipment change and a gate change just as they were about to board. It took an additional hour to board as they cleaned the plane from storage.

There was no wifi available on this flight. And there were no screens, no onboard entertainment, no entertainment options at all. It was like travelling in the 1990s again, except without even a main screen for options. Seats, as usual, were tight and uncomfortable.

Good seat comfort ORF to ATL. Bad seat ATL to SEA (terrible lumbar support, hard, ouch)..

Because I was moved to an exit row, the snacks in economy comfort, the selection of snacks was better.

I upgraded to first. Quick and easy boarding. Comfortable seat with power and a nice IPA.

Probably not the fault of Delta but there was delay after delay after delay and I ended up getting home 4 hours later then I should have at 1:30 in the morning

No in flight service, no explanation - FC got service, C+ did not, unsure about Economy. No turbulence to speak of, so I guess another way to cut cost, or promote health and well being of Delta employees? Also, boarding in MEM combined zones, and with overhead space already full on both flights after Zone 2/ Diamond, presents a huge challenge to find a space for a bag. Delta, other than point A to B, is no longer reasonable to fly - very poor experiences, not even taking into account the chastising at the gate and rude crews, across the board.

It would have been better if the flight wasn't delayed by 2.5 hours

Unfortunately weather delayed our flight waiting for our plane to arrive and due to a little snow time was needed to deice the plane so departure was very delayed and I missed the connecting flight

Very good. Because of the delays with my previous flight, I missed my connection, but I was able to book another flight through the United app easily.

I wish there were outlets to charge my iPhone. The crew was great; we had a female pilot who was great with explaining what was happening and delays,

The flight crew where really good. Better then the crew from BNE to SFO

Delayed, toilets did not flush, pilot parked to far away from Gate

Was happy we finally got upgraded in 1st class. The seat getting old. The cushiness need some improvement.

Yet another flight in which beverage and snack service was skipped. Other that that, firmly mediocre. Landed early, to gate late due to congestion at the gates. Airline's fault or airports fault: unknown.

Miserable. They moved my seat, but canceled the next leg of my flight. I resolved the issue at my transfer, but that resulted in lost luggage that has taken days off my schedule with no resolution. Worse, they fail to interface effectively with Lufthansa, forcing me to bounce between two equally useless help desks. The apps are unable to handle the situation, the bag dropped off the tracker, and while the call centers are polite, they do not provide written information to assist with cross-airline communication.

left on time, reasonable boarding process arrived early luggage came out quickly

I like flying first class, and United has a nice one

Trip delayed for 2 hours because of rain. We boarded and have to get down the flight and reboard again.

The aircraft had several problems - from excess fuel to non operational ac. Two hours of delay in Chicago could have been avoided with proper planning and aircraft maintenance.

This flight captain and crew were amazing, started ahead of time of departure and reached 30 mins before arrival time. Amazing!

Long delays, lack of information about the status of the flight. The flight was delayed 4 times.

Could we please end the loud announcements about credit card offers on your flights? We are trying to sleep, work, watch videos, etc. and if we need a credit card, we will ask for one. Flying is already not what it used to be.

I would like the crew to talk LESS over the PA and specifically about credit card offers. I am trying to work, sleep, watch a movie and the PA was booming about a credit card offer. Could we go back to the days when the customer was more important than selling a credit card?

No enough space plus only allowing one laggage instead of two like other airlines.

It was good. But the gate team made me check my carry on when there was plenty of space for my luggage on the plane. Otherwise our trip was fine.

The entertainment options were at best, fair. It was exactly the same as my outbound flight. It would have been more entertaining if there were some series from Apple TV, HBO, Showtime or other carriers for me to catch up with.

Concern Regarding Significant Gate Delay and Jet Bridge Issue Dear Customer Relations Team, I am writing to express my disappointment with the experience I had on my recent flight AA 2414 on Sunday January 18, 2026. What should have been a routine departure turned into a frustrating and avoidable delay due to an issue with the jet bridge at the gate. As a result, the flight was delayed by approximately 90 minutes while multiple gate changes were attempted. The lack of clear communication during this period made the situation even more challenging. Passengers were left uncertain about the cause of the delay, the expected timeline, and the next steps. This not only disrupted travel plans but also created unnecessary stress for everyone on board. I understand that operational issues can arise, but a malfunctioning jet bridge and the resulting extended delay suggest an area where procedures or equipment maintenance may need attention. I hope you will review this incident to prevent similar disruptions in the future. I would appreciate acknowledgment of this concern and consideration of appropriate compensation for the inconvenience and lost time caused by this delay. Thank you for taking the time to review my experience. I look forward to hearing from you. Sincerely, Dion Dillard
