Security lines at SLC
SLC has identified peak departure times when higher volumes of passengers depart; the airport homepage shows a live security wait estimate.
Busiest times: 7:00am, 10:00am, 4:00pm, 8:00pm, 10:00pm.
Nationally, TSA checkpoints are busiest from 5 to 7 AM local time. See TSA's hourly numbers and the busiest days to fly.
TSA PreCheck: PreCheck is at the main Level 2 checkpoint; SLC lists regular PreCheck hours there as 3:30am-10:00pm, so late-night travelers may not have a PreCheck lane. TSA PreCheck enrollment is offered in the CLEAR lane.
CLEAR: Available at this airport (see terminals below for which checkpoints).
Touchless ID: TSA lists Touchless ID at 65 airports and tells travelers to check with their airline. Delta lists SLC as a participating airport with dedicated Touchless ID bag drop. A March 2026 third-party list shows Alaska, American, Delta, Southwest and United participating at SLC.
