Because I can’t stand very long in one place, I was allowed to reword.

Because I can’t stand very long in one place, I was allowed to reword.

Re-checking our bags, the workers were not able to help us with boarding passes for the flight, told us to wait, then ignored us while they helped many other passengers. Until I got rude, they would have left us standing there, and even then they were very curt and dismissive in telling us where to get boarding passes printed. We made it to the gate just as they were starting to board passengers. It was just rude customer service.

While I received notice that AA 478 was delayed, the flight departed PHX and arrived PHL more than two hours late. The first class cabin service was mediocre; there were no pre-departure beverages offered; there were no warm mixed nuts served with cocktails; there was no personal greeting to me as an Executive Platinum member by the first class flight attendant. While the flight operated safely, its arrival at 0219 in the morning in PHL ended a very long day. I do not feel that American provided first class service.

Absolutely filthy flight and not equipped for a trans US

This flight was late and did not meet the connecting flight.

Turn on the heat. Flight was way too cold from Arizona to Chicago.

Poor on time performance. Flight was delayed due to a lightbulb. No updates from the pilot. Plane was dirty and hot, AC didn't work well.

Being back games on the in-flight entertainment. Also your flight attendants need a break, raise, or overall attitude adjustment.

Overall pleasant was delayed and caused transportation issue when landing

Good over all but my flight from. Miami to Barbados the airplane was very dirty like I have never seen before. It looked like that plane hasn’t been cleaned in a long time and I fly about one time a month.
