SLC Airport Connection Times: How Long You Need

Salt Lake City Airport has one terminal feeding two long, parallel concourses: A and B. Both are connected airside, so most connecting passengers can walk straight to the next gate without collecting checked bags or clearing security again. The real constraint is the distance between gates.

The final seven Concourse B-east gates open October 27, 2026. United arrivals and departures will principally use the new far-east gates, with two gates available for common use. That makes the far end of Concourse B especially relevant for United passengers; recheck the airport map and your assigned gate after opening rather than relying on an older terminal screenshot.

How much connection time do you need at SLC Airport?

For a domestic connection at SLC, 45 minutes is usually workable when the flights use nearby gates, but 60 minutes is the better target when changing between Concourses A and B. Allow 90–120 minutes after an international arrival because customs, baggage handling and security screening add unpredictable time.

These are practical planning targets, not airline ticketing rules. An airline may sell a shorter legal connection, but that does not create extra time when the inbound flight is late or the gates are at opposite ends of the airport.

If a missed connection would be especially costly—the last flight of the day, separate tickets, children, limited mobility or an international itinerary—add more time. SLC’s accessibility guidance also recommends arranging wheelchair or guided assistance with the airline in advance.

Official SLC gate walking times

These are the airport’s own published figures, not a guess. “Riding” means walking while standing on the moving walkway; oddly, just standing still on one is slower than walking normally, because the belts move slower than a typical walking pace.

The number worth knowing: before the central tunnel opened, getting from security to that same midpoint of Concourse B via the old mid-concourse route took 14:58 on foot. The new tunnel does it in 7:05. Less than half. If you’re reading an older blog post that describes SLC as a brutal cross-terminal slog, that’s almost certainly the number it’s quoting, and it’s now roughly cut in half for anyone routed through the current tunnel.

Do you go through security again during an SLC connection?

Domestic connections and domestic-to-international connections remain airside, so passengers normally do not clear TSA security again. An international arrival is different: passengers clear U.S. Customs and Border Protection, handle any required checked-bag transfer, and pass through security before the next flight.

Not flying but want to meet someone at the gate? SLC now participates in Gateside by TSA PreCheck, a free advance visitor-pass program for eligible KTN holders.

The main Level 2 checkpoint is open 3:30 a.m.–1 a.m. The ground-level checkpoint by International Arrivals is open 6 a.m.–5 p.m. and specifically serves arriving international connections as well as departing passengers. TSA PreCheck hours are shorter: 3:30 a.m.–10 p.m. on Level 2 and 6 a.m.–5 p.m. on the ground level.

Those checkpoint hours matter mainly to passengers beginning a trip, arriving internationally or using separate tickets that require a landside bag recheck. SLC follows the general recommendation to arrive two hours before a domestic departure and three hours before an international departure. On unusually busy dates, check the SLC busy-days calendar and add margin.

Is a tight connection survivable?

Every concourse at SLC sits airside, so a same-terminal connection never sends you back through security. That part is genuinely easy. The part that isn’t is distance, and the walking times above are the real constraint.

There is no single public, airport-wide minimum connection time. Airlines validate each ticket using their own rules, and a connection being legal does not mean it will feel comfortable. A 30-minute domestic layover can work when the inbound flight is on time and the gates are close, but it leaves almost no recovery time for deplaning or a gate change.

Do the arithmetic against the walking chart and the honest answer is: 30 minutes is tight even within one concourse and genuinely stressful when the gates are at opposite ends. A far Concourse B-to-far Concourse A transfer can consume roughly 20 minutes in walking alone, before deplaning, wayfinding or a crowded moving walkway. If the layover is under 45 minutes, check the next gate in the airline app before landing and go there first. Ask the flight crew or a gate agent for help when a delay puts the connection at risk.

If you have time to kill

Concourse B got a real upgrade recently: a second Delta Sky Club, roughly 34,000 square feet and seating 600, opened near Gate B31 (the airline’s second-largest Sky Club anywhere in its network), alongside a new American Express Centurion Lounge one level up, also by Gate B31. Concourse A’s original Sky Club is on Level 2, east of the Airport Plaza. Check the airline or lounge app for current hours and access rules before walking away from the departure gate.

For quieter seating without a lounge membership, Vino Volo sits off the main concourse flow and rarely feels as packed as the gate-adjacent spots. Six new concessions are scheduled to open with the final gates on October 27, 2026: Einstein Bros. Bagels, Moochie’s Cheesesteaks, Monarca, Mr. Charlie’s Chicken Fingers, Swig, and &Go SLC. Worth checking the airport’s current dining map to see which landed near your gate by the time you fly.

Frequently asked questions

Is 30 minutes enough for a connection at SLC?

It can be enough for an on-time domestic flight with nearby gates, but it is not a comfortable buffer. Deplaning and a gate change can consume most of the layover. A 45-minute connection is more workable; 60 minutes is better when changing concourses.

Is one hour enough for a layover in Salt Lake City?

Yes, one hour is enough for most domestic connections at SLC when the inbound flight is on time. It leaves time to walk between Concourses A and B through the central tunnel. It is not enough for every international arrival or a separate-ticket transfer requiring baggage claim and recheck.

Can you walk between Concourses A and B at SLC?

Yes. The concourses connect airside through the central tunnel, so no shuttle or second TSA screening is needed for a normal domestic connection. Moving walkways assist along the route.

How long is the walk to Concourse B at SLC?

The airport’s official chart measures 7 minutes 5 seconds from the main security checkpoint to Concourse B through the central tunnel when walking without using the moving walkways. Reaching a far-end B gate takes about 13 minutes 50 seconds from security. Gate-to-gate time depends on both gate locations.

What happens after an international arrival at SLC?

Connecting passengers clear U.S. Customs and Border Protection, handle any required checked-bag transfer, and go through security before continuing airside. Allow 90–120 minutes rather than treating it like a domestic connection.

What should I do if I miss my SLC connection?

Use the airline app or speak with a gate agent immediately. On a protected single-ticket itinerary, the airline normally handles rebooking after a delay. Separate-ticket travelers carry more risk. If the next flight is not until the following day, compare hotels near SLC Airport, and check free shuttle hours and late-night pickup before choosing a room.

Arriving, not connecting

Baggage claim is on Level 1. Rental car counters are across two bridges from baggage claim, in the Gateway Center next to the parking garage. Rideshare pickup is a short walk from the baggage claim doors on the ground level. The TRAX Green Line platform is about a five-minute walk away via a covered walkway. The airport doesn’t publish an official minute figure for that walk, so treat it as a solid estimate rather than a measured one.

SLC says arriving bags take an average of about 15 minutes to travel from the aircraft to baggage claim. That is a systemwide average, not a promise for an individual flight, so leave margin before scheduling a curb pickup or ground transportation connection.
