Several delays. Next flight was worse. Did not arrive home until 2am PT

The flight to Tokyo AA61 took off about two hours late, but then had to turn back. By that time the crew had to be replaced. Then they kept promising to take off in an hour, then in 3, then switch to the next day.

Any sort of gluten free snack option would be nice

I had a carry on and a personal bag. I put my personal item under my seat and on way to the seat I put my bag up. I usually close my eyes and rest as I was on call for last 36 hours. I heard very loud announcements that someone needs to identify their bag. Pretty sure it was not mine until the hostess pointed out my jacket details attached to the bag. I asked why she got my bag out. I got berated and did not want to create a scene. But this person needs to be talked to.

On time arrivals and departures. Gate boarding notices could be better if displayed on monitor.

Between Las Vegas and Dallas was okay But, once in the Dallas airport, notice, I have disability and ask for a wheelchair, they leave in a middle of nowhere, the personal in charge try to push me on a cart where I couldn't sit because was to high. Then they don't care about me, they bulling, till I start to yelling and crying, ask to everyone around, who can help me. The man in charge make a despective movements and said you are to loosing the fly. The last name in his batch started with an H, I did not have the full name. A nightmare. After all, a woman in charge was walking very slowly and asking me for a tip cause she was helping me to reach the fly. For years, AA has been the preferred airline. The personal in charge of the disabled people are discriminate me. Thank you Kayak.

American Airlines Suck. AA did not deliver us to the airport we paid for to Tulum. Instead, we were flown into Cancun and had to take a shuttle to Tulum. Instead of arriving at 4 PM, we arrived at 11:30 PM - not to mention that our initial booked flight was due into Tulum at noon. The latter flight was canceled and rebooked (to the 4 PM arrival). We lost a day of vacation. Oh, I forgot that AA provided a lunch voucher for $12. Noting, the least expensive item on the menu at the airport restaurant was green beans for $9.99. The return flight from Tulum was delayed two or three times for no reason other than that it was NOT related to the weather. We arrived late for our connecting flight from DFW to STL. Luckily, the connecting flight was delayed. We hurried through Customs and ran through the airport to make our flight to STL (or we would have missed that flight).

Flight was late and missed connecting flight. They could have better accommodated, but instead did an overnight and had to arrive the next afternoon.

2/29/2025: Tulum to DFW. Delay as usual with no explanation from AA. Three friends and I had a connecting flight from DFW to STL. We would have missed the latter without the delayed connecting flight, dashing through customs, and running through the airport. Did I mention our trip to Tulum on American was rerouted to Cancun and shuttle from Cancun to Tulum, arriving at our resort destination at midnight vs the 4 PM scheduled arrival? AA provided a lunch voucher for $12.00. The least expensive menu item was $9.99 for green beans. I will avoid traveling with AA as much as possible.

April was the flight attendant in first class and was the most pleasant, cordial and efficient person I have seen on a flight in years. Good example of the type of people AA should hire to increase customer satisfacdtion.
