Posting in the AS forum because I’m flying AS, and your JFK experience can vary greatly by terminal.
Flight is at 9am on a Wednesday. Flying F and have TSA Pre. Staying at an airport hotel the night before. Things I care about, in order: 1) departing on time. 2) Sleeping in, arriving at the airport as late as possible, and getting through security fast as possible. 3) Overall In-flight experience (example, Airbus with Viasat > Older 737 with GoGo).
Any suggestions based on personal experiences?
