How delays work at MIA

A ground stop holds flights bound for MIA 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

  • Allow at least 90 minutes for an international connection, and more if you must re-check bags.
  • Summer afternoon thunderstorms and hurricane season (June to November) can cause delays.
  • A taxi from MIA to South Beach is a short ride, but take the Metrorail if you are staying downtown.
