Can't say I liked anything. There is no legroom, the flight attendants lack personality, the food is not good, and the entertainment must contain every low budget movie ever made. Never heard of at least 95% of the movies and television shows in the catalog. Also don't like the fact that I paid to check in my luggage, but it was being offered free at the gate. I am an AA credit cardholder, but don't like flying American.
