How delays work at DSM

A ground stop holds flights bound for DSM 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

  • Three family restrooms are in the terminal. One is across from the Southwest ticket counter near baggage claim, and two are post-security: one near Gate C7 and one at the end of the A concourse downstairs (A5).
  • A Mamava nursing pod, sponsored by UnityPoint Health, is located immediately after the TSA checkpoint, across from the DSM Police desk.
  • Use the live shuttle tracker on flydsm.com to see when the next shuttle arrives.
  • Conference rooms are available for business meetings. Contact the airport at (515) 256-5100 for rental information.
