If the service crew didn't make difference between people and they change my seat without asking me if is okay or not with me

Great for a small Commuter. Quiet and relaxing. Seats were better than most.

The plane was late getting to Ontario by half an hour which makes it inconvenient when you have people waiting for you.

Luggage handling and communication is extremely poor. I landed in india 15th and recived luggage today. Based on my itag the luggage was in Germany. They kept me in dark. Etihad num er in india was non operatuonal. Had to call USA etihad. It should not be so difficullt. I came for 1 week business trip everything was screwed . This is the first and also will be last for me

There was no service on the flight even though there was no turbulence or any other issues on the flight. Nobody greeted at the entry or leaving the airplane, staff crew looked annoyed and not helpful at all.

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.
