Old dirty plane but great lie flat seats in business class

Old dirty plane but great lie flat seats in business class

Business Class layout was excellent. The seats were not nearly as comfortable as UA, Delta or Air New Zealand (the best). Nor were the controls as flexible. Food was okay but not great. Breakfast pancakes were like cardboard.

Communication not good, too many changes. Three flights were cancelled due to weather and the options were not acceptable. I had to cancel my Canada portion of the trip.

On time and stellar premium class service. Not liking non LCD display in seat backs - miss the convenience of not using your own device.

My flights were all delayed , mostly due to technical issues with AA aircrafts. I had to rebook my trip 4 times . I lost my whole day and finally arrived in LAX around midnight. This was a very bad experience with American airlines , I will always try to avoid flying with them

The boarding by groups is pointless. The first two groups worked fine, but almost Noone boarded in goups three thru five leaving the vast majority boarding when group six was called. It defeated the purpose of spreading out the crowd.

I blame kayak for my last trip to dca. Kayak cancelled my direct flight and put on a one stop flight and made lost whole day from my vacation and had not even refunded my ticket.

delayed multiple times. no resolution on anything from AA customer service. was put on hold in chat to talk to manager. was 6th in line to talk to manager for more than TWELVE HOURS - from sometime around 9AM until well after I had gone to bed that evening. no explanation, no attempt to make it right. just a five hour delay because of repeated maintenance claims

Was the most uncomfortable I ever had in the air. Felt like I was trapped in the seat legs cramped and was just horrible. The flight to DSM was a lot better. Even being on a smaller plane was better. Staff are outstanding. No complaints about the people.

It was exactly as I expected, on time, smooth flight, courteous staff.
