We were told the flight was delayed 5 times, then it was moved to the next day.

We were told the flight was delayed 5 times, then it was moved to the next day.

The experience with American Airlines was good, although the Philippines Airlines flight was much better (better seats, better food, better entertainment options, overall better). Again, the MIA to LAX flight was fine, but nothing in comparison to the comfort and accommodations of the Philippines Airlines flight from LAX to MNL.

Loved the crew . Absolutely no complaints. Except for luggage lost

Flight delay was communicated before leaving for airport which caused it to be a non-event. Great flight and crew!

Wish some foods provided rather than just biscuit/cookie for flight more than 2 hours

The flight attendant, a black woman with curly hair who sat near Row 21, was wonderful and kind.

We are too tired and frustrated to comment politely at this point

It took way too long to diagnose and solve the problem of a broken crew member cabin seat. Though compensation for the volunteer who left the flight was very kind.

We fly American Airlines quite a bit. And we always fly business class when traveling internationally. We were a bit disappointed with the comfort of this particular plane as well as the entertainment options.

The AA staff person who checked our bags was curt and almost rude. The FA also seemed unhappy doing her job. Overall it was like riding the school bus back in grade school.
