Flew from Belize to Dallas. The final leg was to El Paso. There was a delay, again with no explanation as to the reason except for some vagueness about repairs. When I suggested to the agents that customers do better when they are given information, the agent replied that they had no information. I then suggested that he ask. Customer service is simply horrible.
Also on flight from Belize seat did not recline.

Our plane was changed to a 777 wide body plane. We upgraded to have more legroom, so the seats were so comfortable and it was a newer plane. We were able to lean back and also use foot rests. Very comfortable and on time, all good. We did not use the in flight entertainment.

The check in process was easy. They took my luggage that was checked through to San Francisco and was an easy transfer in Dallas to the waiting baggage handlers in the customs area. And it arrived within minutes of arriving in San Francisco. They served dinner and breakfast with a smile. and the entertainment console provided plenty of free movies..

We were delayed over an hour. The staff suffered with us in the warm waiting area. The pilot said he would try and increase the speed to make up time which I definitely appreciated because I had a connection.

The staff was generous with water, helpful when my display didn't work.

Flight was completely booked. Not a single sit was empty. Airline staff worked fast and efficiently to get all on board and out of the gate on time. Flight attendants were also very efficient to get all their drinks and such and with a full flight this is something difficult. Seats were OK, nothing to write home about. Each seat had screen and good movies, USB port and connector. Will fly again AA for sure.
