Discuss PGroot's answer to: Where to park for international flights?

You need to say what airport, and perhaps which airline, before anyone can tell you which terminal your international flight departs from.  Chicago O'Hare (ORD) has different terminals than San Francisco (SFO) or New York (JFK, EWR, LGA).

San Francisco has some Mexico departures from terminals 1 and 2 but arrivals and most departures are from the International Terminal.
