Where Is Seattle Airport Parking Located? (Address & Map)

The SEA Airport parking garage sits directly next to the main terminal at 17801 International Blvd, SeaTac, WA 98158. It is the only on-airport parking facility and serves every concourse through a single connected structure. A skybridge links the garage to the terminal between Concourse B and Concourse C.

Once inside the terminal, follow overhead signs to reach your concourse. Alaska Airlines flights depart from Concourses C and D. Delta flies from Concourse A and the South Satellite. Southwest and JetBlue operate from Concourse B. The garage is open 24 hours a day, 365 days a year. You can pay with cash, Visa, Mastercard, Amex, Discover, Apple Pay, or contactless payment at exit.

Before you drive, check real-time traffic on Waze — especially during morning rush hour or around major events. SEA sits 14 miles south of downtown Seattle, and I-5 traffic can stretch your drive from 25 to 45 minutes depending on the time of day.

How Do You Get to Sea-Tac Airport Parking from I-5 North and South?

Most drivers reach SEA via Interstate 5, the primary north-south freeway running through the Seattle metro area. The route is straightforward from both directions.

From I-5 Southbound (coming from Seattle or Tacoma)

1. Take Exit 154B for WA-518 East toward Sea-Tac Airport.
2. Follow WA-518 east for about 1 mile.
3. Take the Airport Expressway S exit toward the airport.
4. Follow signs for Parking — stay in the left lane for the garage entrance.
5. Choose a WHITE lane for Reserved Parking (Floor 4) or a BLUE lane for General Parking.

From I-5 Northbound (coming from Tacoma or Federal Way)

1. Take Exit 154 for WA-518 West toward Sea-Tac Airport.
2. Follow WA-518 west, then merge onto the Airport Expressway S.
3. Stay in the right lane and follow Parking signs to the garage.
4. Enter via the WHITE lane (Reserved) or BLUE lane (General) at the toll plaza.

Important tip: If you enter the wrong color lane by mistake, let the attendant know at the gate. They can redirect you. Do not back up — this creates hazards. The garage entry lanes use automated ticketing, so your entry time stamps immediately when you pull a ticket.

What Are the Directions to Sea-Tac Airport Parking via WA-99 / International Blvd?

State Route 99, also called International Boulevard or Pacific Highway South, runs parallel to I-5 along the west side of the airport. This is the most direct route for drivers coming from Burien, Tukwila, or Des Moines — and it's where most off-site parking lots are located.

Directions to the On-Airport Garage via WA-99

1. Head north or south on International Blvd (WA-99).
2. Turn east onto S 176th St or follow signs for Airport Expressway S.
3. Follow the expressway into the airport loop.
4. Follow Parking signs to the garage entry lanes.

Directions to Off-Site Lots via WA-99

All major off-site lots — Doug Fox Airport Parking, MasterPark Lot A, Jiffy Airport Parking, WallyPark, ShuttlePark2, and Ajax Parking R Us — sit along or just off International Blvd. Look for each lot's signage on WA-99 before you reach the airport entrance. Most are within 3 to 10 minutes of the terminal by shuttle. Doug Fox is the closest at just 3 minutes away.

If you're coming from West Seattle or Burien, State Route 509 connects directly to the airport area and feeds onto International Blvd. Drivers from the Eastside (Bellevue, Renton, Kent) typically use Interstate 405 to SR-518 west toward the airport.

For a full breakdown of which off-site lots offer the best value on WA-99, see our guide on Seattle airport off-site parking rates and lots.

How Far Is the Parking Garage from the Sea-Tac Terminal?

The on-airport garage connects directly to the terminal building via a covered skybridge — you never have to walk outside. The skybridge enters the terminal between Concourse B and Concourse C. From there, internal corridors and moving walkways connect you to all other concourses and satellites.

The walk from most garage floors to the terminal takes around 5 to 10 minutes, depending on how far up you parked. Elevators are available on every floor. Accessible parking spaces sit closest to the elevators and skybridge entrance on each level, fully ADA-compliant with proper signage.

If you parked at an off-site lot, the shuttle drops you at the 3rd floor of the parking garage, in the Courtesy Vehicle area. From there, you cross the skybridge into the terminal — a short walk of about 2 to 3 minutes. The shuttle pickup on return works the same way: exit baggage claim, follow signs to the Courtesy Vehicle area on the 3rd floor garage level, and call or wait for your lot's shuttle.

What Is the Difference Between Reserved and General Parking at Sea-Tac?

Reserved Parking is located exclusively on Floor 4 of the on-airport garage and costs $39/day (or $273/week) per the Port of Seattle (verified May 2026). General Parking uses all other floors and costs $5/hour with a daily maximum of $32 (or $149/week).

• Reserved Parking (Floor 4): Pre-bookable, guaranteed space, $39/day — enter via the WHITE lane
• General Parking (all other floors): First-come, first-served, $32/day max — enter via the BLUE lane
• Cell Phone Lot: Free, located at the Off Airport Expressway south of the terminal — for brief waits while picking up arriving passengers

Reserved parking is worth booking if you're traveling during peak periods — summer weekends, holiday weeks, or around major events like the 2026 FIFA World Cup matches in Seattle. The garage holds roughly 13,000 vehicles, but general spots fill fast on busy travel days. For more on what to do if the garage is full, see our article on Seattle airport parking when the lot is full.

How Much Does Seattle Airport Parking Cost? (On-Site vs. Off-Site Comparison)

On-site garage parking starts at $32/day for General and $39/day for Reserved. Off-site lots along International Blvd cost as little as $12.95/day — saving you up to 60% compared to the on-airport garage. All verified rates are current as of May 2026.

Which Off-Site Seattle Airport Parking Lots Offer Shuttle Service?

Every major off-site lot near SEA includes a free 24/7 shuttle — no extra charge. Shuttles pick you up at your car or parking stall and drop you at the 3rd floor Courtesy Vehicle area of the on-airport garage. From there, the skybridge takes you into the terminal.

• Jiffy Airport Parking: Attendants come to your car. ~6-minute ride. Fenced, well-lit lot.
• ShuttlePark2: Shuttle picks up at your stall. 7-10 minutes to terminal.
• Ajax Parking R Us: Free shuttle to and from SEA. Gated, well-lit.
• MasterPark Lot A & Garage: On-demand bright yellow buses — the largest eco-friendly fleet at SEA. EV charging available via Juicer.
• Doug Fox Airport Parking: Fastest shuttle at SEA — just ~3 minutes to terminal. Oldest and closest off-site lot.
• WallyPark Outdoor & Premier Garage: Shared shuttle every 15-20 minutes. Free WiFi and coffee while you wait. Text 'shuttle' to (425) 336-2193 for return pickup from Premier Garage.

All shuttle drop-offs and pickups use the same 3rd floor Courtesy Vehicle area in the on-airport garage. On return, head to that level after collecting your bags and call or wait for your lot's shuttle. Most operators run on-demand, so waits are typically under 10 minutes. Budget an extra 20-30 minutes on travel days during peak periods like summer and holidays.

What Should You Know Before Parking at Sea-Tac? (Tips, EV Charging & Accessibility)

A few practical details can save you time and money on parking day.

EV Charging at SEA

The on-airport garage offers 48 free EV charging stations — charging is included in your regular parking fee (no extra charge). Stations use the ChargePoint network. If you prefer to plan ahead, download the ChargePoint app for EV drivers to check station availability before you arrive. Off-site, both MasterPark Lot A and MasterPark Garage offer EV charging via Juicer, and WallyPark Premier Garage also has EV charging.

Accessibility

ADA-compliant accessible spaces are available on every floor of the on-airport garage. They sit closest to the elevators and the skybridge entrance. All elevators are ADA-accessible. If you need mobility assistance inside the terminal, contact your airline in advance — SEA staff can arrange wheelchair service from the parking level.

Security and Arrival Time

Budget time for parking, the skybridge walk, check-in, and security. TSA security screening guidelines recommend arriving at least 2 hours before a domestic flight and 3 hours before an international flight. Enrolling in TSA PreCheck can cut your security time significantly. SEA has dedicated PreCheck lanes at multiple checkpoints.

Construction Heads-Up for 2026

The SEA Gateway Project is improving roadway and terminal frontage throughout 2026. Some lane configurations near the garage entrance may shift temporarily. The parking garage itself remains fully operational. Follow posted detour signs and allow an extra 5-10 minutes if you're arriving during busy periods. The C Concourse Expansion is also targeting completion in Q2 2026, so expect some interior signage changes near that area.

Book in Advance for Peak Travel

Summer weekends, the Thanksgiving and Christmas travel windows, and 2026 FIFA World Cup match dates in Seattle are the busiest parking periods. General Parking fills first. If you need guaranteed access, book Reserved Parking (Floor 4) in advance or pre-reserve at an off-site lot. Pre-booking through comparison tools often unlocks lower rates than drive-up pricing.
