Airport hub guide
Salt Lake City International SLC: the complete layover guide
One brand new terminal, two concourses joined by tunnels, a Delta lounge empire, and the easiest connections of any major US hub. Here is how to spend a layover at Salt Lake City without stress.
Layover verdict Excellent for 2 to 6 hour layovers if you fly Delta or carry the right Amex card, because everything sits airside in a single 2020 built terminal with no rescreening between gates. Thinner for everyone else, since independent lounge options barely exist.
Best lounge play The Concourse B Delta Sky Club, opened October 2025 at nearly 34,000 square feet, is the second largest in Delta's network. Amex Platinum holders get the Centurion Lounge near gate B31 instead. Priority Pass holders get Minute Suites in Concourse A plus a massage chair session at XpresSpa near gate A15, and nothing else.
The one thing to know Concourse B is only reachable on foot through underground tunnels. The Central Tunnel, opened October 2024, cut the trek roughly in half, but you should still budget 15 minutes for any gate change between A and B.

Orientation
How Salt Lake City is laid out
SLC is the rare American hub that was rebuilt from scratch this decade. The entire airport you see today opened in phases from September 2020: one terminal, one big security checkpoint, and two long parallel concourses, A and B, joined underground.
The layout is linear and honest. You check in, clear the single checkpoint, and land in the Terminal Plaza at the head of Concourse A. Most non Delta carriers, including American, United, Southwest, Alaska and JetBlue, board from the nearer end of Concourse A. Delta, which treats SLC as one of its core western hubs and operates the large majority of flights here, spreads across the rest of Concourse A and all of Concourse B.
Concourse B is the part that earned the airport its early reputation for marathon walks. There is no train and no bus; you walk. The original mid concourse tunnel sits far along Concourse A and turned a B gate into a hike of close to a mile. The fix arrived on 22 October 2024 when the Central Tunnel opened near the head of the concourses: 1,175 feet portal to portal with six moving walkways and an art installation called The River overhead. Walking it takes about 9 to 10 minutes; standing on the walkways stretches that to about 13. Call any A to B gate change a 15 minute job and you will rarely be wrong.
Connections at SLC are about as easy as US hubs get. Every gate is behind the same security perimeter, so a domestic to domestic transfer never involves rescreening, and arriving international passengers are the only ones who re enter security after customs. On a single ticket, a 45 minute connection within the same concourse is comfortable when your inbound runs on time. Add the tunnel for an A to B change and 60 minutes feels relaxed. On separate tickets, give yourself 2 hours or more because you are starting from check in again.
Leaving the airport is cheap and simple. The TRAX Green Line light rail station sits at the south end of the terminal, and trains reach downtown Salt Lake City in roughly 20 minutes for a 2.50 dollar single fare. Trains run about every 15 minutes, from around 5:30 am to 11:30 pm on weekdays with a thinner weekend schedule. With 4 free hours and an interest in Temple Square or a proper meal, the train beats sitting at the gate. Just respect the evening cutoff on the way back.
Concourse by concourse
What each concourse gives you
Concourse A
The main event. Concourse A connects directly to the terminal and security, hosts every non Delta airline plus a large share of Delta departures, and holds most of the airport's dining and shopping along one long, bright corridor with mountain views on both sides. The Delta Sky Club here opened with the new terminal in 2020 at around 28,000 square feet and features the Sky Deck, an outdoor terrace overlooking the airfield with the Wasatch Range behind it, a genuine reason to arrive early. Minute Suites sits near gate A33 and rents private rooms with daybeds by the hour, the closest thing SLC has to in terminal sleep. A Starbucks in the Terminal Plaza runs 24 hours, which matters more than it should at 3 am.
Concourse B
All Delta and Delta Connection, reached only through the tunnels, and since late 2025 the stronger lounge address. The new Delta Sky Club opened on 28 October 2025 at just under 34,000 square feet with room for about 600 guests, a wrap around premium bar, nine soundproof phone booths and panoramic airfield views; it is the second largest Sky Club in the network. A few gates away, the Amex Centurion Lounge near gate B31 opened in October 2025 with nearly 18,000 square feet and seating for about 350, open daily from 4:45 am to 11:15 pm. If your itinerary and cards give you a choice of concourse, B now wins for lounge time, A wins for food courts and the outdoor deck.

FAQ
Salt Lake City layover questions
Can I sleep overnight at SLC airport?
The terminal stays open 24 hours and travelers with a boarding pass are generally tolerated overnight, though SLC offers no dedicated rest zones. Whether the airside concourses stay accessible all night is to be confirmed; plan around the landside Terminal Plaza, where a Starbucks runs 24 hours. For real sleep, Minute Suites in Concourse A rents private rooms by the hour, and several airport hotels run shuttles.
How do I get between Concourse A and Concourse B at SLC?
On foot, through one of two underground tunnels, with no new security screening. The Central Tunnel near the head of the concourses is 1,175 feet long with six moving walkways and takes about 9 to 13 minutes portal to portal. Budget 15 minutes gate to gate for any A to B change at Salt Lake City.
Is wifi free at Salt Lake City airport?
Yes. SLC provides free wifi throughout the terminal and both concourses on the SLCAirport.wifi network, with no time limit advertised. It handles video calls in most gate areas.
Does SLC have a Priority Pass lounge?
Not a traditional one. As of June 2026 the Priority Pass options at Salt Lake City are Minute Suites in Concourse A near gate A33, where members typically get the first hour covered, and a short massage chair session at XpresSpa near gate A15 on select memberships. The Delta Sky Clubs and the Centurion Lounge do not accept Priority Pass.
Is 45 minutes enough to connect at SLC?
Usually, yes, on a single ticket. Every gate sits behind the same security perimeter, so domestic connections involve no rescreening. Within one concourse, 45 minutes is comfortable; add the 15 minute tunnel walk for an A to B change. Arriving from abroad, clear customs first and allow 90 minutes or more.
How do I get from SLC airport to downtown Salt Lake City?
Take the TRAX Green Line light rail from the station at the south end of the terminal. Trains run about every 15 minutes and reach downtown stops near Temple Square in roughly 20 minutes for a 2.50 dollar single fare. Weekday service runs from about 5:30 am to 11:30 pm, with reduced weekend hours.

Denver International (DEN)
The other big Rocky Mountain hub, about 90 minutes away by air. Far larger than SLC, with a train between concourses instead of a tunnel walk.
Las Vegas Harry Reid (LAS)
A common pairing with SLC on western itineraries. Slot machines at the gate, a very different overnight mood, and a livelier landside.
Phoenix Sky Harbor (PHX)
The American Airlines hub to the south. Multiple terminals and a Sky Train, so connections there play by different rules than SLC.
