How delays work at MDT

A ground stop holds flights bound for MDT at their origin airports. A ground delay program spaces arrivals out so the airport is not overloaded. Departure and arrival delay messages describe the average wait the FAA expects. None of these tell you whether your own flight is late, so always check your airline as well.

Local tips

  • The public side of the terminal is open 24 hours, but the TSA checkpoint closes overnight. Vending is on the first floor.
  • Dining after security is for ticketed passengers only. Vending machines before security stock snacks and drinks.
  • Luggage lockers and storage are not available due to federal security rules.
