How delays work at GUM

A ground stop holds flights bound for GUM 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

  • For a quick pick-up, the first 15 minutes cost $2 in the short-term lot.
  • Long-term parking drops to $11 a day after the third day, so stays of a week or more cost less per day.
  • Check the Sagan Bisita opening hours before you plan a visit, because the hours vary across sources.
  • The lot accepts Visa and Mastercard, so bring one of those cards for payment.
