3:30 am – 12:00 am. The airport passenger terminal is open to the public at approximately 3:30 AM and closes shortly after the last arriving flight, usually around midnight.

Airlines recommend that passengers arrive at least 90 minutes prior to their departure time to be able to check in and complete the security screening process for an on-time departure.

It is important to allow extra time so that everyone can get through the screening process in a timely manner to avoid flight delays.  For more information, please contact your airline.

Checking a bag? Airline baggage check ends 45min before departure.

TSA security typically opens about 90 minutes before your scheduled departure. Because ITH has a limited number of daily departures, the checkpoint is not open 24 hours.

If your flight is delayed, please note that TSA may not remain open for the full duration of the delay—especially if other flights have already departed. For this reason, we recommend that all travelers arrive around their flight’s originally scheduled departure time, even if the airline shows a delay. This ensures you can clear security and be ready when boarding begins. Flight delays can sometimes be reversed, and we’d hate for you to miss your flight due to a schedule change or TSA closure.

The airport runway is open 24 hours a day, but flights arriving overnight should call ahead to verify available services.

6:00 am – 10:00 pm. Call (607) 257-7500 for late fly-ins.
