I just noticed that my flight tomorrow, PHL-LAX #797, is leaving from Gate A18. I would imagine that I can check in at Terminal A, even though it is the "international" terminal, correct?

(An interesting aside: it seems that the reason why this flight leaves from Gate A18 is because it has the same flight number as an incoming flight from TLV which arrives at Gate A19. It seems pretty bogus to consider "Flight #797, TLV-LAX" a direct flight, especially since there must be a plane change -- PHL-LAX is on an A321.)
