Short flight

Attendant at gate insisted my daughter's carry-on bag get checked because he put it crooked into the sizer. When I adjusted it and showed him that it fit, he still insisted that we check it. Unpleasant way to start our trip.

None of the experience was pleasant

First flight was delayed causing us to miss the 2nd flight and we ended sleeping on a chair at the airport waiting for a morning flight. AMERICAN AIRLINES didn't even have the decency to put us in a hotel for the night due to their delay. Then they added a 2nd lay over which was delayed for hours also. Traveling was to visit my mother who had cancer and I was sick so this made the trip even more distasteful.

What you expect from an internal US flight: no food, crowded flight, cramped seats. I have come to expect two things - arrive on time and arrive safely. The good, we arrived safely.

Pulled away from gate and sat on tarmac for over an hour while technical difficulties fixed. We should not have boarded until plane was ready. We arrived over one hour late and just made connecting flight. Our luggage was not so fortunate.

The crew was nice

I flew American four times in 7 days, every flight was delayed. delay times varied from 90 minutes to over three hours. Fog in Chicago was beyond anybody's control, but the other times were not weather related, I recently flew frontier Air and their flights were also late. I jinxed myself by stating I never have this issue with AA. Great job at proving me wrong. I flew a good bit last year and these issues didn't start until after the new year., Thank you for your time.

Delayed flights leading to incredibly tight connection times, staff inconsistent with messaging re the source of the delay, zero compassion for customers, offering $700-$1,400 to get off the plane when you charge $200 to change a flight 2 weeks in advance is especially galling! Will not fly with United again whenever there is a viable alternative to my destination.

Can’t think of anything nice to say...

On a cross-country flight from San Francisco to DC, you would think United could provide more than one snack option that is void of any nutritional value, and perhaps they could provide alternatives for their patrons with allergies. Is fresh fruit really too much to ask for on a 6-7 hour flight??

getting off the plane was very time consuming despite being already landed. Not entirely sure why but this was the first time getting off a plane took some time. im sure the staff was working hard but I’m unsure why it took some time.

I've always wanted to go to all five Manhattan boroughs in one day. Thanks to Delta, that happened.

The plane broke down as we were about to take off. Delta rebooked everyone on to new flights because it was pretty obvious that plane was not going to be fixed in time. The crew did their best given the situation. The situation was absolute bs though - we had to take a cab to JFK for our new flight and do the whole security thing again and all that annoying stuff. Thanks for wasting 8 hours of my life, Delta.

I liked the check-in kiosk, but only because I had no bags to check. I liked being able to choose my own seat. I liked that the flight was uneventful. I liked the staff at all stages, they were friendly and helpful.

They made me shove my purse into my knapsack to fit within their two bag policy. That's a first for me. My Delta flight did not do that.

Flight was under booked so there was plenty of room.

Crew was unexpectedly loud/chatty with one another throughout the flight, even when things were quite and calm they were calling over our heads to one another and laughing loudly. Initially, it's an international flight from Spain and no crew members in my section atleast could speak Spanish. I had to help a passenger who only spoke spanish because the attendant kept repeating an order in english, just getting louder each time.

The breakfast on the international flight was pretty good. However, there were more frequent snacks and healthier options when I flew internationally on Delta.

I didn’t like that my pre-flight request for gluten-free snacks/meals was ignored. I didn’t like the attitude of one flight attendant who couldn’t bring herself to empathize with my allergy to gluten— which causes painful cracks in my palms and fingers.

It did not register my touch very well. It was hard to navigate through the movies as the scroll interface didn't work smoothly. The whole system needs to be updated, including the hardware.

The gate attendants and on-board crew were lovely. Pilots provided info which was great and made up some of the long delay.

There is not enough space to list everything. I paid $800 for a normally $300 flight, then paid an extra $75 for the ability to board early so I could store my very small roller carry-on. The in-bound flight was 2 hours late and even though I could track that easily, and assumed our flight would also be two hours late, the AA website insisted the outbound flight would be on time. So like everyone else, I went to the airport. And it wasn't until just before the original departure time that the update was indicated. Really?? If I knew the flight was going to be two hours late,that means AA knew, and didn't care enough about their passengers to advise them. Then when we boarded, my bag was taken away for gate check because the flight did not allow roller bags. After I paid extra. How can AA not advise you when you book your flight that roller bags would not be allowed?? Talk about a money-grab. I unfortunately have a return ticket and am not wealthy enough to throw it away and book on another airline, but I would if I could. I will never fly AA again and I will share my story far and wide.
