With only one terminal, Morristown Airport isn't the busiest airport around. Still, ensure you arrive with sufficient time to check in and pass through security. We wouldn't want you to miss your flight! Avoid the last-minute dash to your departure gate, or the dread of missing your flight, by arriving 1.5-2 hours before domestic flights. Arrive at the airport 2-3 hours before if you're flying internationally. This will give you enough time to check in luggage, pass through security and customs and make your way to your gate. If you want the most accurate advice, check the arrival time recommendations of both your departure airport and airline.
