HND - JFK

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.
