Bag drop was very disorganized in Miami. All main cabin passengers were shunted to just a few lanes and they had an equal number of lanes for first class passengers but there was nobody on those lines. They did nothing to bring the main cab and passengers over to the open lines and they just had employees standing there and doing nothing

Crew at the gate was very crabby and not at all polite. The plane was very hot the entire flight. And the seat cushion was very worn out.

I have never been assaulted they way I was today in Charlotte - shame on American

The staff are very, very professional. It's what flying should feel like.

The flight attendant in business class was excellent! Professional, friendly and attentive.

A first class seat should fit a fat person, and this doesn't. The trays in the armrest are less functional than an ordinary tray in the back of the seat.

I would have liked a pillow. The vegetarian wrap and oaten cake was good.

It was great. Smooth flight, comfortable, left on time and landed on time.

Perhaps this is an airport issue, but being in a takeoff queue for over an hour in the taxiing lane is unacceptable. We will definitely be seeking alternative avenues for air travel in the future.

Really good. I accidentally left my duffel on the plane and the reps were so friendly in retrieving it.
