How delays work at PWM

A ground stop holds flights bound for PWM 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

  • Park in the Pink Lot for the lowest daily rate, but allow extra time for the shuttle.
  • Check whether your flight is in a peak period, and plan to arrive 1.5 hours early.
  • Use the Ground Transportation booth outside baggage claim for taxis and limos.
  • Keep your REAL ID handy, since passengers without one face a $45 fee.
