How delays work at BWI

A ground stop holds flights bound for BWI 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

  • Long-Term parking at $11 a day is the cheapest option, and the airport says the price you see is the price you pay with no hidden fees.
  • Use the rail station garage at $12 a day if you are arriving by train, and check the rail shuttle schedule before you go.
  • The Hourly Garage is closest to the terminal and worth the extra cost for a short trip.
  • Check which checkpoint your airline uses before you walk in, so you do not join the wrong security line.
  • The Long-Term shelters have real-time monitors that show when the next shuttle arrives, which helps on early departures.
  • Check the live availability on the airport parking page before you drive, because a full garage sends you to another lot.
