Layover in Salt Lake City International (SLC): What to Do Hour by Hour
One terminal, two concourses, a Delta hub, and a famous walk that a new tunnel finally tamed. Salt Lake City is one of the easier American airports to connect through.
- Layover verdict
- Comfortable from 2 hours on a domestic connection: one security perimeter, no rescreening between gates, and two lounges from late 2025 that rank with the best in the country. From about 6 hours, downtown is 20 to 25 minutes away by train for 2.50 dollars.
- Best lounge option
- The Delta Sky Club in the center of Concourse B, opened October 2025 across two levels, is the strongest room in the airport. Amex Platinum holders get the Centurion Lounge by gate B31. Priority Pass holds no full lounge here, only Minute Suites and XpresSpa in Concourse A.
- The one thing to know
- The walk. Concourse B sat more than 2,000 feet from the terminal until the central River Tunnel opened in October 2024 and cut the trip by as much as half. The far ends of both concourses still run 15 to 20 minutes from security on foot, so check your gate number before you settle anywhere.
Ground rules
How connecting at Salt Lake City actually works
Salt Lake City replaced its cramped old three terminal complex in September 2020 with a single new terminal feeding two parallel piers, Concourse A and Concourse B. Concourse A handles most Delta flights plus the other carriers; Concourse B is the overflow and growth pier. Two underground tunnels link everything: the mid concourse tunnel between A and B, and the central River Tunnel from the terminal straight to Concourse B, each about 1,200 feet long. Delta runs roughly 70 percent of the airport's operations, so most connections here are Delta to Delta.
Domestic connections are the easy case. Every gate sits inside one security perimeter, so you walk straight from one gate to the next with no rescreening. The only enemy is distance: gate to gate across the far ends of A and B can take 20 to 25 minutes, moving walkways included. Airlines sell domestic connections here down to about 45 minutes, and they usually work. Booking your own, take 75 minutes or more and you can stop hurrying.
Arriving from abroad is the slow case. International arrivals clear immigration on the lower level of the terminal, collect checked bags, hand them back at the recheck belt, then pass through security again to reach the gates. Plan on about an hour for the whole sequence when queues behave. Connections are sold from around 60 minutes for international to domestic; 90 minutes to 2 hours is the honest number.
Hour by hour
What your Salt Lake City layover hours buy you
3 hours
Plenty of time, spend it deliberately
Three hours on a domestic connection at SLC is genuinely relaxed, because no rescreening means the whole gap is yours. Decide first whether your next gate is at a far end; if so, bank 20 minutes for the walk. Then eat. The Concourse B Plaza added a cluster of newer concessions in October 2024, and both concourses have sit down options that beat anything on your next flight.
Without lounge access, the best free entertainment is the glass: the concourses face the Wasatch Range, and for most of the year the gate windows frame snow on the peaks. Find a seat with a view and charge everything.
5 hours
Lounge hours, and SLC suddenly has good ones
Five hours makes the lounges worth the walk. The Delta Sky Club in the center of Concourse B opened in October 2025 across two levels and almost 34,000 square feet, the second largest in the network; it runs 5:45 am to 10:30 pm daily. The original Sky Club in Concourse A, east of the plaza on level 2, opens earlier, 4:45 am to 11:15 pm. The Amex Centurion Lounge next to gate B31 brings a terrace and a barista for Platinum and Centurion cardholders, 4:45 am to 11:15 pm.
Priority Pass is the thin spot. There is no full Priority Pass lounge at SLC: the card gets you the first hour free at Minute Suites near gate A33, with extra time at 34 dollars an hour, or 25 minutes in the XpresSpa chairs in Concourse A. A private room for a flat hour of sleep is honestly a decent trade on a long gap.
8 hours
Downtown is on the table
Eight hours buys you the city. The TRAX Green Line leaves from the station at the south end of the terminal, costs 2.50 dollars one way, and reaches downtown in 20 to 25 minutes, with trains roughly every 15 minutes on weekdays and every 20 on Saturdays; Sunday service is thinner, so check the UTA timetable before counting on a tight return. Get off around Temple Square or City Center and the core sights sit within a few blocks: Temple Square itself, still partly behind construction screens while the Salt Lake Temple renovation runs on, and the City Creek Center mall directly across the street.
The math: be back at the terminal 90 minutes before a domestic departure, 2 hours before an international one, and allow 30 minutes of travel each way. That nets 4 hours or so downtown from an 8 hour layover. Bags are the catch. SLC has no left luggage facility inside the airport; through checked bags stay with the airline, but anything you are carrying comes with you or goes to an app based storage spot downtown, typically 4 to 8 dollars a bag per day through services like Bounce.
Overnight
The building stays open, your comfort does not
SLC stays open 24 hours, so nobody will throw you out, but it makes no effort to host you. There are no rest zones or cots, most seating has fixed armrests, and travelers consistently report the terminal running cold overnight. The one real bed airside is Minute Suites near gate A33, open around the clock, where an overnight block runs about 195 dollars, which is hotel money for a windowless cabin.
For anything past a miserable doze, take a shuttle. A ring of hotels minutes from the terminal runs free airport shuttles, including the Hyatt Place, Courtyard, Radisson and Microtel; shuttle hours vary by property, so confirm before a 2 am arrival. The full bench by bench breakdown lives in our guide to sleeping in Salt Lake City airport overnight.
City escape
Leaving SLC between flights
Leaving is realistic from about 6 hours. The Green Line makes this one of the cheapest airport to downtown runs in the country at 2.50 dollars, and the station is inside the terminal complex, no shuttle required. Downtown Salt Lake City is compact and flat around the Temple Square grid, so 3 hours on the ground covers the square, City Creek Center, and a proper meal without rushing. In winter, remember the city sits at 4,300 feet, so dress for the street.
Documents are simpler than at most international hubs because there is no transit area: if you arrived from abroad you already cleared US immigration at SLC or your first US airport, so stepping outside costs nothing extra. Non US citizens need whatever visa or ESTA authorization got them into the country in the first place; verify entry requirements before travel. The remaining planning questions are bags, covered above, and the return buffer: 90 minutes domestic, 2 hours international.
FAQ
Salt Lake City layover questions
Do I go through security again when connecting at SLC?
Not on a domestic connection: every gate in Concourse A and Concourse B sits behind one security perimeter, so you walk straight from plane to plane. Arriving from another country, you clear immigration, collect and recheck any bags, and pass through security once before reaching your departure gate.
How long do I need to connect at Salt Lake City?
Domestic to domestic, 45 minute connections are sold and usually work since there is no rescreening, but gate to gate across the far ends can take 20 to 25 minutes on foot; 75 minutes is comfortable. International to domestic, allow 90 minutes to 2 hours for immigration, bag recheck and security.
Which lounges can I use during an SLC layover?
Delta Sky Clubs sit in both concourses: Concourse A east of the plaza, 4:45 am to 11:15 pm, and a two level club in the center of Concourse B, 5:45 am to 10:30 pm. The Amex Centurion Lounge is next to gate B31. Priority Pass has no full lounge at SLC, only Minute Suites near gate A33 and XpresSpa in Concourse A.
Is 8 hours enough to see downtown Salt Lake City?
Yes. The TRAX Green Line runs from the terminal to downtown in 20 to 25 minutes for 2.50 dollars, every 15 minutes on weekdays. Counting a 90 minute domestic or 2 hour international return buffer, you net around 4 hours for Temple Square and City Creek Center.
Can I sleep overnight at SLC airport?
The airport stays open 24 hours, so you can stay, but there are no rest zones, most seats have armrests, and the terminal runs cold. Minute Suites near gate A33 sells private rooms around the clock with overnight blocks at about 195 dollars. Nearby hotels with free shuttles are the better value.
