My seat was assigned last row behind restrooms No legroom’s I’m very Pettit Still was not comfortable Food choice was excellent

The chicken wrap was tiny ($13 for what looked like a 1/3 of a normal wrap?) and disgusting.

Mediocre would be best description. Food bland. Seat biz class uncomfortable to sleep. Crew never dimmed lights completely in an overnight flight to Europe. Would avoid AA if possible.

Small plane, poor meal choices for first class, bad terminal and boarding experience at LAX

Massimo, flight attendant was very authentic, attentive - wonderful. Food/wrap was just okay.

Experience was great. The best part is the free Wi-Fi connection which helps me to work on the flight

The flight was fine. It's the satellite terminal that supports American eagle flights is what sucks. There is only one food option and everything there is way overpriced. I mean I know it's airport pricing, but it's even crazier than that. I bought a sandwich in a plastic container for $18.

The flight was really crowded. Flight attendants were just ok.

Flight was delayed for 2 hours, then last minute the change to on time. The satélite location is far and a nightmare to get to.

We flew in first class. The crew did not offer drinks before the flight took off, but they treated us well during the flight. The food was excellent. There was actually too much food served, but it was nice to have all the options.
