What to expect at MDT
How busy the airport is through the day, from scheduled departure volume.
Scheduled departures by hour
The busiest hour is 6 AM, with about 4 departures a day, against roughly 0 at 9 PM. Counterintuitively, that peak is also more punctual than a typical hour here — early banks fly aircraft that have been on the ground overnight rather than ones inheriting the day’s delays.
