Complete Guide to Airport Timing
Salt Lake City International Airport (SLC) is Utah's largest airport and a major Delta Air Lines hub. The airport opened a brand new terminal in 2020, featuring modern design and efficient operations.
How Early Should I Arrive at SLC for a Domestic Flight?
Arrive 2 hours before departure for domestic flights. The new terminal is efficient and well-designed, but you still need time for parking, check-in, security screening, and reaching your gate. During ski season and peak travel times, arrive earlier.
How Early Should I Arrive at SLC for an International Flight?
Arrive 3 hours before departure for international flights. The international gates require extra time for check-in procedures and security screening.
When is SLC Most Busy?
SLC's busiest periods are 5am-8am and 4pm-7pm. Winter ski season creates additional peak congestion, especially on weekends.
How Much Time Should I Allow for Traffic to SLC?
Traffic on I-80 and I-215 is generally lighter than other major cities. From downtown Salt Lake City, allow 15-25 minutes during normal times, and 25-35 minutes during rush hour. Winter weather can add significant time during snow storms.
Which SLC Terminal Should I Go To?
SLC has one main terminal building (opened 2020) with two concourses: Concourse A (Delta and partners) and Concourse B (all other airlines). The terminal is modern and easy to navigate, with all concourses connected post-security. Check your airline to know your concourse.

Frequently Asked Questions
What are current SLC wait times?
The live SLC wait at the top of this page updates every few minutes from the airport's own checkpoint data. On a typical day, standard security takes about 15-25 minutes, and the busiest times are usually 5am-8am and 4pm-7pm.
How early should I arrive at SLC for a domestic flight?
Arrive 2 hours before your domestic flight departure. SLC requires time for the drive (15-35 minutes from most locations), parking or drop-off (10-15 minutes), check-in and bag drop if needed (10-15 minutes), security screening, and walking to your gate (5-10 minutes). The new terminal is efficient, but Delta flight banks and ski season weekends create peak congestion.
How long does security take at SLC?
On a typical day, standard security at SLC takes about 15-25 minutes, longer at the busiest times (usually 5am-8am and 4pm-7pm). Check the live wait at the top of this page before you leave. Ski season weekends (December-March) can see longer waits. TSA PreCheck usually shortens your wait.
What is the new SLC terminal like?
SLC's new terminal opened in September 2020, replacing the old terminal completely by 2024. It features modern design, efficient security checkpoints, better dining and shopping options, and improved layout. The terminal has two concourses (A and B) connected by a central tunnel with a moving walkway. Natural light, local artwork, and nods to Utah's outdoor heritage create a pleasant traveler experience. Most passengers report the new terminal is much easier to navigate than the old one.
Does ski season affect SLC wait times?
Yes! Winter ski season (roughly December through March) brings significantly more travelers to SLC, especially on weekends when skiers are arriving or departing. Friday afternoons, Saturday mornings, and Sunday evenings can see exceptionally long security lines and check-in delays. If you're traveling during ski season weekends, add an extra 30 minutes to your normal arrival buffer. Bag-drop lines can also be very long as skiers check ski equipment.
