Extremely fast boarding. Great food. Polite flight attendants. Leg space in regular economy is the largest I have experienced.

Poor|Aug 2025

The plane was delayed due to maintenance after everybody boarded (1 hour), the inside of the plane was not air conditioned before takeoff, and the weather outside was hot. Upon arriving in JFK, there were further delays. The airline attendants were passive aggresive and not certainly were not polite.

I thought it will be Japan Airlines on the way back to New York too. So I was soooo disappointed. I never expected that it will be American Airlines.
