Salt Lake City Airport Security Wait Times Today
The Salt Lake City Airport security wait time estimates below show the typical SLC queue at the centralized checkpoint for this hour and day of week. Unlike most large US airports, Salt Lake City International Airport (SLC/KSLC) operates a single terminal building with one shared security checkpoint on Level 2, serving both Concourse A and Concourse B through the same lanes. There is no separate checkpoint for each concourse. After clearing security, passengers walk to their concourse via underground tunnels within the secure zone. Security wait times at SLC vary by time of day, day of week, and whether you are travelling during the winter ski season, which adds a distinct seasonal pressure not seen at most airports of comparable size.
How Long Is Security at Salt Lake City Airport?
Security wait times at Salt Lake City Airport depend on the time of day, the day of week, and the season. The checkpoint handles the full volume of SLC departures through one central facility on Level 2, equipped with 20 Automated Screening Lanes. During quiet midweek windows from 10:00 to 15:00 outside of ski and holiday periods, most passengers clear the standard lane in 8 to 12 minutes. During the morning peak from 05:00 to 09:00, waits of 20 to 35 minutes are common in the standard lane as Delta’s morning departure bank from Concourse A coincides with high volumes from Concourse B carriers including Southwest, United and American. The afternoon peak from 15:00 to 19:00 generates similar conditions on most days.
TSA PreCheck members at SLC typically clear the dedicated PreCheck lane in under 8 minutes at most hours. CLEAR members who also hold PreCheck get the fastest experience available: CLEAR handles the identity verification step at a biometric kiosk while PreCheck handles the physical screening with no shoe, laptop or liquid removal required. Both programs are available at the SLC checkpoint. Delta Digital ID, operated in partnership with TSA, gives eligible Delta customers on the Fly Delta app access to the PreCheck Touchless ID lane, where a camera verifies identity by facial matching without the need to show a physical ID. For passengers who do not hold PreCheck or CLEAR, the B-Fast-style pay-per-trip option is not available at SLC. Enrolling in TSA PreCheck before your next SLC trip is strongly recommended for anyone who flies regularly from Salt Lake City.
After clearing the single checkpoint, passengers walk through The Plaza to reach their concourse via one of two underground tunnels. Concourse A, primarily serving Delta Air Lines, is accessible directly from The Plaza with a walk of approximately 5 to 10 minutes to the mid-concourse gate area. Concourse B, serving Alaska, American, Southwest, United and other carriers, is accessed via the Central River Tunnel or the Mid-Concourse Tunnel, with a walk of approximately 10 to 18 minutes to the mid-to-far concourse gates. Passengers do not need to re-clear security to move between concourses. This airside connection means that a connection at SLC between any two airlines in different concourses does not require exiting and re-clearing, which is a significant operational advantage compared to multi-terminal airports like LaGuardia or New York JFK.
Salt Lake City Airport Security Technology and Checkpoint Design
The New SLC airport, built in phases between 2020 and 2026 at a cost of approximately $5.1 billion, was designed from the outset with passenger throughput as a central priority. The centralized security checkpoint on Level 2 is equipped with 20 Automated Screening Lanes, which allow multiple travelers to simultaneously load their items into bins. Once a bin enters the screening tunnel, the system automatically returns it to the front of the lane, eliminating the wait for bins that slows older conveyor systems. The HOK-designed checkpoint was engineered to process passengers up to 30 percent faster than the previous airport facility.
SLC was also the first US airport to deploy second-generation Credential Authentication Technology at every lane in its checkpoint. The CAT system scans a passenger’s photo ID while simultaneously capturing a real-time photo of the passenger, comparing the two automatically. This removes the manual boarding pass check from the process and speeds the document verification step. TSA PreCheck members at SLC can additionally use the Delta Digital ID lane, where facial matching via the Fly Delta app replaces all document presentation at the checkpoint entirely. The combination of ASLs, second-gen CAT and TSA PreCheck Touchless ID makes SLC one of the most technology-forward security checkpoints among mid-size US airports.
The TSA 3-1-1 liquid rule applies to all standard lane passengers at SLC: each container must be 3.4 ounces or 100ml or less, and all containers must fit in a single clear quart-sized resealable bag placed in a bin for screening. TSA PreCheck members are the main exception and can leave liquids and laptops in their carry-on bag during screening. A July 2025 TSA policy change allows passengers to keep shoes on at checkpoint lanes equipped with newer footwear imaging technology capable of scanning shoes without removal. Follow TSA officer instructions at the checkpoint as lane-by-lane capability varies.
Salt Lake City Airport Security Wait Times by Concourse
Salt Lake City Airport’s two concourses share a single security checkpoint. The wait time at the checkpoint is the same regardless of which concourse you are heading to. What differs between Concourse A and Concourse B is the gate walk time after clearing security and the airlines you will find there. Both concourses are accessible from The Plaza immediately beyond the checkpoint, and both are connected to each other airside via underground tunnels. Your concourse is determined by your airline, not your destination. Confirm your concourse from your boarding pass or airline app before you travel.
Concourse A Security and Gate Access (Delta Hub)
5 to 10 minutes from the Level 2 checkpoint to mid-concourse gate area. Concourse A runs west from The Plaza and is the closer of the two concourses to the checkpoint. Gates at the far western end of Concourse A-east take approximately 12 to 15 minutes. Moving walkways are positioned along the concourse to reduce effective walk time. Allow extra time during peak ski weekends when Concourse A is at its busiest with Delta departures to West Coast, Northeast and international destinations.
Concourse A stretches 3,700 feet from The Plaza toward the west side of the airfield. It has 47 gates including 6 dedicated international gates on the eastern section of Concourse A used for Delta’s international services. Destinations from Concourse A include domestic routes across the US, Delta’s seasonal transatlantic services to Paris Charles de Gaulle and Amsterdam, Korean Air codeshare flights to Seoul Incheon (launched in 2025), and routes into Canada and Mexico via codeshare partners. The Delta Sky Club at Concourse A is the largest in the Delta network by floor area, with an outdoor Sky Deck terrace, two bars, a fireplace and shower facilities. A second Delta Sky Club opened in Concourse B-east in 2025. The international arrivals area is on Level 1 of the main terminal, separate from departures. Passengers arriving from international destinations clear US Customs and Border Protection on Level 1 before exiting to the ground floor. TSA PreCheck enrollment can be completed via the CLEAR kiosks in the concourse. The USO Lounge for military personnel is also located in Concourse A.
Concourse B Security and Gate Access (Multi-Carrier)
10 to 14 minutes from the Level 2 checkpoint to the mid-concourse gate area via the Central River Tunnel. The tunnel connects The Plaza to the Concourse B Plaza, where the allosaurus fossil replica and world map installation are located. Gates at the far eastern end of Concourse B, including the new Phase 4 gates opening in October 2026, take 16 to 20 minutes from the checkpoint. Moving walkways are positioned along most of Concourse B to assist with the walk distance. Southwest and Delta departures have shifted some operations into the expanded Concourse B-east following the October 2025 Phase 4 partial opening.
Concourse B runs north of The Plaza and is the larger of the two concourses in terms of airline diversity, serving domestic carriers including Alaska, American, Frontier, JetBlue, Southwest and United, plus international carriers Air Canada, KLM, Aeromexico, Hawaiian and WestJet. Southwest and Delta Air Lines have additional departures from Concourse B-east following the October 2025 expansion. Concourse B currently has 36 operational gates and is expanding to 47 total gates when Phase 4 completes in October 2026. The final 11 Phase 4 gates at the eastern end of Concourse B remain under construction as of April 2026. A second Delta Sky Club opened in Concourse B-east in October 2025 and is the company’s second largest in the world. The American Express Centurion Lounge, the only non-airline-specific lounge at SLC, also opened in Concourse B-east in October 2025 and accepts Centurion and Platinum cardholders as well as Priority Pass members paying a day pass rate. A United Airlines Club is planned for the far eastern end of Concourse B as part of Phase 4. The duty-free shop at SLC is located in Concourse A near gate A23, not in Concourse B.
Salt Lake City Airport Security Peak Hours and Best Times to Fly
The two busiest daily windows at Salt Lake City Airport security are 05:00 to 09:00 (driven by Delta’s morning departure bank from Concourse A and the first Southwest, United and American departures from Concourse B) and 15:00 to 19:00 (the afternoon and early evening departure surge across both concourses). Saturdays are the single most congested day of the week at SLC for most of the year, driven by ski resort turnover when one wave of guests departs and another arrives. Sundays are the second busiest. Fridays see elevated volumes from the end-of-week business travel push.
SLC has a pronounced seasonal peak that distinguishes it from most US airports of comparable size. The winter ski season from December through March consistently generates above-average volumes, with the most intense pressure on Saturday mornings when guests from Park City, Snowbird, Alta, Deer Valley, Brighton and Solitude depart following a Saturday checkout. MLK weekend in January and Presidents Day weekend in February are the two busiest holiday weekends at SLC and routinely generate standard lane waits exceeding 30 minutes before 09:00. Late February and early March spring break periods also add significant volume. The combination of ski resort proximity and strong leisure demand makes SLC’s seasonal pattern quite different from a business-dominated hub like Chicago O’Hare or a leisure gateway like Las Vegas.
The quietest windows at Salt Lake City are 10:00 to 15:00 on weekdays outside of ski and holiday periods and after 20:00 on any day of the week. A Tuesday or Wednesday midday departure during the non-ski shoulder months of May, June or September represents the most relaxed combination at SLC. The pre-dawn window from 03:30 to 05:00 is also very quiet but builds quickly once Delta’s first departure bank begins.
| Time of Day | Typical SLC Security Wait (Standard Lane) | Status |
|---|---|---|
| 03:30 to 05:00 | Under 8 min | Quiet |
| 05:00 to 06:00 | 10 to 16 min | Moderate |
| 06:00 to 09:00 | 20 to 35 min (longer on ski weekends and holidays) | Peak |
| 09:00 to 10:00 | 14 to 20 min | Busy |
| 10:00 to 15:00 | 8 to 12 min | Quiet |
| 15:00 to 16:00 | 12 to 18 min | Moderate |
| 16:00 to 19:00 | 18 to 32 min | Busy |
| 19:00 to 20:00 | 12 to 18 min | Moderate |
| 20:00 to 23:00 | 6 to 10 min | Quiet |
| 23:00 to 03:29 | Under 8 min | Quiet |
Salt Lake City Airport Priority Security: TSA PreCheck and CLEAR
Priority security at Salt Lake City Airport runs through the TSA program system. There is no pay-per-trip priority pass equivalent to the B-Fast product at LaGuardia Terminal B. The two main ways to move through SLC security faster than the standard lane are TSA PreCheck and CLEAR. Delta customers have a third option in Delta Digital ID, which provides access to the TSA PreCheck Touchless ID lane for eligible Fly Delta app users. Business class and first class ticket holders who are not enrolled in any of these programs queue in the standard lane regardless of cabin class.
Recommended Arrival Times at Salt Lake City Airport
For domestic flights, Salt Lake City Airport and TSA recommend arriving at least 2 hours before departure. SLC’s single checkpoint serves the full daily departure volume of both concourses. Once through security, passengers access both concourses airside via underground tunnels, so there is no inter-concourse shuttle and no risk of arriving at the wrong building. Factor in check-in or bag drop, ground transport to the airport, and the gate walk time for your specific concourse and gate position within it. SLC is connected to downtown Salt Lake City via the TRAX Green Line light rail, which departs from a station adjacent to the terminal and reaches downtown in approximately 20 minutes for a flat fare. TRAX is a reliable option during peak ski weekends when road congestion can significantly extend drive times.

Tips to Beat Salt Lake City Airport Security Queues
A few practical decisions reduce your time in the SLC security queue regardless of which concourse you are heading to.
- Enroll in TSA PreCheck before your next SLC flight. At $78 for five years it is the most cost-effective security upgrade available at Salt Lake City. The PreCheck lane at SLC typically clears in under 8 minutes even during the morning peak and on ski weekends. Apply at tsaprecheck.com, at an enrollment center, or via the CLEAR kiosk at the airport.
- Allow extra time on peak ski weekends. MLK weekend and Presidents Day weekend in January and February are the two busiest non-holiday weekends at SLC. Standard lane waits before 09:00 on Saturday of these weekends frequently exceed 30 minutes. If you are flying home after a ski week, plan to be at the airport by 05:00 for early departures on those weekends.
- Check the live wait time display before you leave. The official SLC display at slcairport.com and in the SLC Airport app shows current checkpoint conditions. If the app is showing a 30-minute wait and your flight is at 08:00, leaving 20 minutes earlier is significantly more effective than hoping the queue clears. The display updates frequently during staffed hours.
- Use TRAX on peak ski weekends. The TRAX Green Line runs directly from downtown Salt Lake City to the airport terminal in approximately 20 minutes for around $2.50. On Saturday mornings during ski season when ride-share and taxi demand spikes and road congestion into the airport can be significant, TRAX is a far more predictable option than driving or rideshare.
- Factor in the Concourse B gate walk. If your gate is at the far eastern end of Concourse B, especially after the Phase 4 expansion opens in October 2026, the walk from the checkpoint via the Central River Tunnel can take 16 to 20 minutes. Do not treat the security estimate and the gate walk as the same time block. Build both into your buffer separately.
- Pack liquids in your checked bag. The 3-1-1 rule applies at all SLC checkpoint lanes for standard passengers. Removing the liquid bag step speeds the screening conveyor and reduces the chance of a secondary bag check. With Delta’s hands-free bag drop and RFID baggage tracking on all Delta flights, checked bag management at SLC is efficient.
- Use mobile boarding passes and self-service check-in. All major Concourse B carriers including Southwest, United, American and Alaska support mobile boarding passes. Delta at Concourse A offers Digital ID touchless bag drop averaging around 30 seconds per transaction. Both reduce time at the check-in level before you reach security.
- Avoid the 06:00 to 09:00 window if possible during ski season Saturdays. The combination of Delta’s morning bank from Concourse A and the heavy ski guest departure wave on Saturday mornings from December through March creates the most congested single window of the SLC week. If your flight departs at 07:30 on a ski Saturday and you do not hold TSA PreCheck, arriving by 05:15 gives you the best chance of clearing the checkpoint before the main wave hits.
Salt Lake City Airport Layout and Concourse Overview
Salt Lake City International Airport (SLC/KSLC) is located approximately 4 miles west of downtown Salt Lake City, Utah, making it one of the most centrally located major airports in the western United States. It handled a record 28.3 million passengers in 2024 and is ranked among the 25 busiest airports in the country, serving over 330 daily departures to more than 100 nonstop destinations across North America, Europe, Asia and Latin America. The airport is the primary hub for Delta Air Lines in the Intermountain West and the main gateway to Utah’s ski resorts, national parks and outdoor recreation destinations. It is operated by the Salt Lake City Department of Airports and is preparing for significantly increased volumes ahead of the 2034 Winter Olympics and Paralympics, which will be centred on Salt Lake City and its surrounding resorts.
The airport layout consists of a single modern terminal building opened in phases from 2020 to 2026, flanked by two linear concourses: Concourse A (Delta, running west from The Plaza) and Concourse B (all other carriers, running north and accessed via the underground Central River Tunnel). The concourses are connected airside by two underground tunnels, so passengers can walk freely between any gate in the airport after clearing the single Level 2 checkpoint without exiting or re-clearing security. There is no inter-terminal shuttle and no risk of arriving at the wrong building. The terminal has three levels: Level 1 for international arrivals and ground transportation, Level 2 for baggage claim and the security checkpoint, and Level 3 for check-in counters. The TRAX Green Line light rail station is adjacent to the terminal entrance and provides a direct 20-minute service to downtown Salt Lake City.

Salt Lake City Airport Security: FAQ
How long is security at Salt Lake City Airport in 2026?
Salt Lake City Airport has one centralized security checkpoint on Level 2 of the main terminal, serving both Concourse A and Concourse B. During off-peak weekday windows from 10:00 to 15:00, most passengers clear the standard lane in 8 to 12 minutes. During the morning peak from 05:00 to 09:00 and the afternoon peak from 15:00 to 19:00, waits of 20 to 35 minutes are common. The winter ski season from December through March adds significant pressure, particularly on Saturday mornings when resort guests depart for Park City, Snowbird, Alta and Deer Valley. TSA PreCheck and CLEAR members typically clear in under 8 minutes. The official wait time display is available at slcairport.com and in the SLC Airport app.
What are TSA PreCheck and CLEAR at Salt Lake City Airport and how do they work?
TSA PreCheck costs $78 for a five-year membership and gives access to the dedicated PreCheck lane where you keep shoes, belt and light jacket on and leave laptops and liquids in your bag. Most PreCheck members at SLC clear in under 8 minutes. CLEAR costs $189 per year with discounts for Delta SkyMiles members and select credit card benefits. CLEAR uses biometric identification to verify your identity at a kiosk, letting you skip the document check queue and proceed directly to physical screening. CLEAR is available at SLC. Delta Digital ID gives eligible Delta customers on the Fly Delta app access to the TSA PreCheck Touchless ID lane using facial matching. Combining CLEAR with TSA PreCheck gives the fastest possible experience. Global Entry includes TSA PreCheck at no additional cost; an enrollment center is located in the International Arrivals area on Level 1.
When is Salt Lake City Airport security busiest?
The two busiest daily windows are the morning peak from 05:00 to 09:00 and the afternoon peak from 15:00 to 19:00. SLC also has a pronounced seasonal peak driven by winter ski tourism: from December through March, Saturday mornings are particularly intense as resort guests depart after a weekend checkout. MLK weekend in January and Presidents Day weekend in February are the two busiest non-holiday weekends at SLC. Thanksgiving week, the Christmas and New Year period, and spring break in late February and March also generate above-average waits. The quietest windows are 10:00 to 15:00 on non-ski-season weekdays and after 20:00 on any day.
What time should I arrive at Salt Lake City Airport?
For domestic flights, arrive at least 2 hours before departure. For international departures from Concourse A, including Delta routes to Paris, Amsterdam and Seoul, arrive at least 3 hours before departure. During the winter ski season and major holiday periods, add 30 to 45 minutes to both recommendations. SLC road access can be congested during peak ski weekends; TRAX light rail from downtown is a more reliable option in those conditions. TSA PreCheck and CLEAR members can reduce the domestic recommendation to 90 minutes during off-peak non-ski-season periods. The official SLC wait time display is at slcairport.com and in the SLC Airport app.
Does Salt Lake City Airport have automated screening lanes?
Yes. The centralized security checkpoint at SLC is outfitted with 20 Automated Screening Lanes, which allow multiple travelers to simultaneously load bins and automatically return empty bins to the front after screening. The checkpoint also uses second-generation Credential Authentication Technology, which scans a passenger’s photo ID and captures a real-time comparison photo, removing the need to show a boarding pass at the document check station. TSA PreCheck members can leave laptops and liquids in their carry-on bag regardless of lane type. The TSA 3-1-1 liquid rule still applies for standard lane passengers. The July 2025 TSA policy change allows shoes to remain on at lanes with newer footwear imaging technology; follow TSA officer instructions at the checkpoint.
What is the difference between Concourse A and Concourse B at Salt Lake City Airport?
Salt Lake City Airport has one terminal with a single security checkpoint on Level 2. Concourse A is located west of The Plaza and is primarily used by Delta Air Lines, including Delta Connection regional services and international routes to Paris, Amsterdam and Seoul. Concourse A has 47 gates, including 6 international gates. The Delta Sky Club is in Concourse A. Concourse B is the north concourse serving Alaska, American, Frontier, JetBlue, Southwest, United, Air Canada, KLM, Aeromexico, WestJet and other carriers. Concourse B is expanding to 47 total gates by October 2026. Both concourses are connected airside via two underground tunnels, so passengers move freely between them after security without re-clearing the checkpoint. Gate walks to the far end of Concourse B take 16 to 20 minutes from the checkpoint.
Does Salt Lake City Airport have a live security wait time display?
Yes. Salt Lake City International Airport displays estimated security wait times on the homepage at slcairport.com and in the official SLC Airport app available on iOS and Android. The app also provides interactive concourse maps, real-time flight information and gate updates. The MyTSA mobile app aggregates passenger-reported wait times for SLC. Delta Air Lines displays estimated security conditions within the Fly Delta app for eligible Digital ID passengers at the TSA PreCheck Touchless ID lane.
How does the ski season affect security wait times at Salt Lake City Airport?
The winter ski season from December through March generates a distinct volume pattern at SLC that is more pronounced than at most comparable US airports. Salt Lake City is within 45 minutes of Park City, Snowbird, Alta, Deer Valley, Brighton and Solitude, and SLC is the primary gateway for ski tourists visiting Utah. Saturday mornings from 05:00 to 10:00 are particularly intense during ski season as resort guests depart after Saturday checkout. MLK weekend in January and Presidents Day weekend in February are the two busiest non-holiday weekends of the year at SLC and frequently produce standard lane waits exceeding 30 minutes before 09:00. Allow an extra 30 to 45 minutes beyond typical estimates on all peak ski weekends and consider TSA PreCheck enrollment before your ski trip.
