Moving between terminals
The two terminals do not connect airside. The free Inter-Terminal Shuttle runs between Terminal 1 and Terminal 2 from about 4 a.m. to 2 a.m., and it may take longer during construction. Changing terminals means leaving security and going through the checkpoint again, so allow at least 45 minutes for the trip.
