SeaTac Airport Parking Map: Floor-by-Floor Guide 2026

Back to Seattle Airport Parking Information | Complete SEA Airport Parking Guide

The SeaTac airport parking map is a guide to the single main parking garage at Seattle-Tacoma International Airport, managed by the Port of Seattle. The garage holds roughly 13,000 vehicles across multiple floors, with General Parking on most levels and Reserved Parking exclusively on Floor 4. A skybridge connects the garage directly to the main terminal between Concourses B and C. Off-site lots along SR-99 and International Boulevard offer an alternative starting at $12.95/day, well below the on-site rate of $32/day.

• One garage serves the whole airport: The main parking structure is the only on-site option — there is no separate short-term or economy lot.
• General Parking costs $5/hr, capped at $32/day (verified April 2026, per Port of Seattle).
• Reserved Parking on Floor 4 costs $39/day and requires an advance reservation.
• 48 free EV charging stations are available inside the garage — the charge itself is included in your parking fee.
• Off-site lots start at $12.95/day and include free 24/7 shuttle service to the terminal.
• The Cell Phone Lot is free — located on the Off Airport Expressway south of the terminal.

What Does the SeaTac Airport Parking Garage Map Look Like? (Floor-by-Floor Guide)

The SEA parking garage is a multi-level structure where most floors serve General Parking and Floor 4 is set aside exclusively for Reserved Parking. Here is a floor-by-floor breakdown based on current Port of Seattle information (verified April 2026).

The skybridge connects the garage to the main terminal between Concourse B and Concourse C. From there, follow signage to reach any concourse — Concourses A, B, C, and D are all accessible from the central terminal. The North Satellite and South Satellite gates are reached via underground inter-terminal trains after clearing security.

Floor 1 also houses the free rental car shuttle, which runs 24/7. Off-site shuttle operators drop passengers on Floor 3 in the Courtesy Vehicle area — this is where you will be picked up when returning from the terminal.

Where Is the SeaTac Airport Parking Garage Located?

The main parking garage sits directly adjacent to the terminal building at Seattle-Tacoma International Airport, in the city of SeaTac, Washington. The garage entrance is accessed via Airport Expressway South, which loops off International Boulevard (State Route 99 / Pacific Highway South).

The garage is a single, connected structure — not multiple scattered lots. It serves all concourses through one terminal entry point via the skybridge. Signage inside the garage is clear, with color-coded lane guidance. White lanes lead to Reserved Parking (Floor 4). Blue lanes direct drivers to General Parking on all other floors. Follow overhead signs from the moment you enter the structure.

The Cell Phone Lot is separate. It sits on the Off Airport Expressway, south of the terminal, and is completely free. It is the right choice if you are waiting to pick someone up and do not want to pay for the garage.

How Do You Get to SeaTac Airport Parking? (Driving Directions from I-5 and WA-99)

The garage is straightforward to reach from either Interstate 5 or State Route 99. Before you leave, check real-time traffic on Waze — the SEA Gateway Project roadway improvements are still underway in 2026 and may cause brief detours near the terminal frontage.

From I-5 (northbound or southbound):

1. Take Exit 154B for State Route 518 West toward Seattle-Tacoma International Airport.
2. Follow SR-518 west to the airport exit ramp.
3. Take Airport Expressway South and follow signs to the parking garage.

From SR-99 / International Boulevard:

1. Head north or south on International Boulevard (SR-99).
2. Turn onto S 170th St or use the Airport Expressway interchange — follow green parking signs.
3. Enter the garage from the Airport Expressway South ramp.

Drivers coming from West Seattle or Burien can also use State Route 509, which connects directly to the airport area. From the Eastside (Bellevue, Renton), take Interstate 405 south to SR-518 west. GPS navigation works reliably here — enter "Seattle-Tacoma International Airport Parking" and most apps route correctly to the garage entry.

What Is the Difference Between Reserved Parking and General Parking at SEA?

Reserved Parking guarantees you a specific stall on Floor 4 of the garage. You book in advance, receive a QR code, and use a dedicated entry lane — no circling required. General Parking is first-come, first-served on all other floors.

• Reserved Parking (Floor 4): $39/day | $273/week | Guaranteed spot | QR code entry | Dedicated lane
• General Parking (Floors 1–3, 5–8): $5/hr | $32/day max | $149/week | No reservation needed | Standard self-park

Reserved Parking costs $7/day more than General Parking. For a one-week trip, that gap grows to $124. The main benefit is certainty — especially useful during holiday travel or for early-morning departures when the garage fills quickly.

Where Can You Find Off-Site Parking Near SeaTac Airport?

Eight verified private lots operate near SEA, all within 3–10 minutes of the terminal by shuttle. Every lot below includes free 24/7 shuttle service — most drop off and pick up on Floor 3 of the airport garage (Courtesy Vehicle area). For a full deep-dive on shuttles and timing, see our guide to SeaTac airport parking shuttle services.

Doug Fox Airport Parking is the closest off-site lot to SEA — roughly 3 minutes by shuttle — making it the fastest option if time is tight. MasterPark Lot A runs the largest eco-friendly shuttle fleet at the airport. For covered parking at a lower price than the on-site garage, MasterPark Garage at $17.99/day or WallyPark Premier Garage at $18.95/day are solid picks.

What Special Parking Options Are Available at SEA? (EV, Over-Height, ADA, Motorcycle)

The SEA garage offers several specialized parking options beyond standard stalls. Here is what is available and where to find it.

EV Charging

The garage has 48 EV charging stations spread across multiple floors. The charge itself is free — you only pay the standard parking rate. If you prefer to plan ahead, the ChargePoint app for EV drivers can help you locate and monitor charging availability before you arrive. Two off-site lots — MasterPark Lot A and MasterPark Garage — also offer EV charging via Juicer. WallyPark Premier Garage provides EV charging as well.

ADA / Accessible Parking

Accessible parking stalls are available on every floor of the garage. They are positioned closest to the elevators and skybridge access points. All spaces are ADA-compliant with proper signage. No advance reservation is required for accessible stalls — they operate on a first-come basis within the General Parking rate.

Over-Height Vehicles

Standard garage clearance handles most passenger vehicles. Travelers with over-height vehicles — trucks, vans, or SUVs with roof racks — should check clearance signage at the garage entrance before proceeding to upper floors. The Port of Seattle recommends contacting the airport directly if you are unsure whether your vehicle fits.

Is It Cheaper to Book Off-Site Parking Near SeaTac Airport?

Yes — off-site lots cost significantly less than parking in the on-site garage. Based on current rates, parking at Jiffy Airport Parking or ShuttlePark2 at $12.95/day saves you nearly 60% compared to General Parking at $32/day. For a seven-day trip, that is a saving of over $133.

• On-site General Parking: $32/day — garage attached to terminal, no shuttle needed
• On-site Reserved Parking: $39/day — guaranteed Floor 4 stall, QR code entry
• Off-site outdoor lots: $12.95–$14.95/day — free shuttle, 3–10 min ride to terminal
• Off-site covered garages: $17.99–$18.95/day — weather protection, free shuttle

The trade-off with off-site parking is the shuttle ride. Add 10–20 minutes each way to your travel time. Most shuttles run 24/7 and are on-demand or arrive every 5–20 minutes. Plan to arrive at the lot at least 30 minutes earlier than you would for the on-site garage. Budget travelers flying from Concourse B (Southwest, JetBlue) or Concourse C (Alaska Airlines) will find the skybridge arrival quick once the shuttle drops them on Floor 3.

Construction is also a factor in 2026. The SEA Gateway Project is improving roadway and terminal frontage access, while the C Concourse expansion ($260M) targets substantial completion in Q2 2026. The parking garage itself remains fully operational throughout all construction. Roadway signage is updated regularly, but budget a few extra minutes for navigation during peak periods near the terminal. For travelers doing overnight trips, compare the math using our guide to Seattle Airport long-term parking rates and lots.

Bottom line: The SEA airport parking garage is convenient and well-located, but off-site lots deliver savings of up to 60% for most travelers. Book in advance — especially for Reserved Parking on Floor 4 — to lock in your rate and avoid surprises on travel day.
