 FACT: There is a scene where Victor and Ameila stand in front of a  map of all the JFK terminals. The "You are Here" indicates that they  are in Terminal 3. Terminal 3 at JFK is Delta. Amelia flies United  which is Terminal 7 and Victor would have flown in to terminal 4  which is for international flights. Neither one of them would have a  reason to be in Terminal 3.
