How delays work at SLC

A ground stop holds flights bound for SLC 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 checkpoint opens at 3:30 a.m., so early morning departures need the earliest arrival times at the terminal.
  • During ski season on weekends and holidays, add extra time to your plans for both security and parking.
  • The TRAX trains run every 15 minutes on weekdays and every 20 minutes on weekends, and the last train leaves around 11 p.m.
  • The Greeting Room is set aside for family and friends waiting for arrivals. It has seating and a local art exhibit.
