Seattle Airport Parking for a Month: 2026 Rates & Tips

Back to Complete SEA Airport Parking Guide

Seattle airport parking for a month is long-term vehicle storage at or near Seattle-Tacoma International Airport (SEA) for trips lasting 30 or more days. Based on official Port of Seattle published rates, on-airport General Parking costs $149/week, which means a full 30-day stay runs approximately $640–$670 on-site. Off-site lots near SEA start at $12.95/day, dropping your 30-day total to as low as $388 — a savings of roughly 40% compared to the on-airport garage.

• On-airport General Parking caps at $32/day or $149/week — a 30-day stay costs around $640–$670 (verified July 2026).
• Off-site lots like Jiffy Airport Parking and ShuttlePark2 start at $12.95/day, cutting that cost to roughly $388/month.

• Booking in advance is strongly recommended for 30-day stays — availability and rates can shift, especially around peak travel periods.

How Much Does It Cost to Park at Seattle Airport for a Month?

The Port of Seattle does not publish a flat monthly rate for public parking at SEA Airport. Instead, daily and weekly caps apply. Per official airport data, General Parking costs $5/hour, capping at $32/day and $149/week. A 30-day stay using the weekly cap works out to approximately $637 (four weeks at $149, plus two extra days at $32 each).

Reserved Parking on Floor 4 of the garage costs $39/day or $273/week. At those rates, a full month of reserved parking can top $1,092. That's a significant premium over General Parking for what is largely a convenience upgrade.

Off-site lots change the equation dramatically. Based on current Triply rates, the cheapest verified options — Jiffy Airport Parking and ShuttlePark2 — both come in at $12.95/day. Over 30 days, that totals just $388.50. You save around $250 versus on-airport General Parking and over $700 versus Reserved Parking.

Rates verified July 2026. Estimates based on 30 days. Off-site lots bill by the day; on-airport uses weekly caps where applicable.

What Are Your Options for Month-Long Parking Near SEA Airport?

For seattle airport parking for a month, you have two main paths: the on-airport garage managed by the Port of Seattle, or one of the independent off-site lots along International Boulevard (SR-99) and nearby roads.

On-Airport Parking

• General Parking — The most affordable on-site option. Self-park in the main garage (~13,000 spaces). Skybridge connects to the terminal between Concourses B and C. Best for those who want the shortest walk to departures.
• Reserved Parking (Floor 4) — Pre-bookable spot closer to the terminal entrance. Higher daily and weekly rates. Adds up fast over 30 days.
• EV Charging — The garage has 48 free EV charging stations included in the parking fee. A real perk for electric vehicle owners on long trips.

Off-Site Parking Lots

• Jiffy Airport Parking — $12.95/day, uncovered, 6 minutes from SEA. Attendants meet you at your car. Free 24/7 shuttle.
• ShuttlePark2 — $12.95/day, uncovered, 7–10 minutes from SEA. Shuttle picks up at your stall and drops at 3rd floor of the parking garage.
• Ajax Parking R Us — $12.99/day, uncovered, 5–8 minutes. Gated, well-lit, free shuttle to terminal.
• MasterPark Lot A — $13.99/day, uncovered. On-demand shuttle with MasterPark's bright yellow eco-friendly buses. EV charging by Juicer available on-site.
• Doug Fox Airport Parking — $14.95/day, just 3 minutes from the terminal — the closest off-site lot to SEA. On-demand shuttle runs 24/7.
• WallyPark Outdoor Self Park — $14.95/day, uncovered, free WiFi, coffee and water in the shuttle lounge. Shuttle runs every 15–20 minutes.
• MasterPark Garage — $17.99/day, covered parking with valet option. EV charging available. Best covered option under $18.
• WallyPark Premier Garage — $18.95/day, covered self-park. Text 'shuttle' to (425) 336-2193 for return pickup. EV charging included.

How Do You Reserve Extended Stay Parking at SEA for 30+ Days?

Booking seattle airport parking for a month in advance is the smartest move. Availability tightens around major holidays, summer travel season, and during the ongoing SAMP construction at SEA — which includes the SEA Gateway roadway project and C Concourse expansion, both targeting completion in 2026.

Step-by-Step: Booking Off-Site Parking for a Month

1. Compare lots on Triply — Enter your departure and return dates at triplypro.com/search?airport=SEA. Rates and availability display side by side for all verified SEA-area lots.
2. Select your lot — Factor in price, covered vs. uncovered, and shuttle frequency. For a 30-day trip, covered options like MasterPark Garage add weather protection worth considering.
3. Enter vehicle details — Some lots require your make, model, and license plate at booking. Off-site lots use this for check-in.
4. Confirm your reservation — You'll receive a booking confirmation with a QR code or reservation number. Save this — you'll need it at the lot entrance.
5. Arrive with buffer time — Off-site shuttles run every 5–20 minutes. Plan an extra 20–30 minutes before your check-in deadline to account for shuttle wait time and the drive to the terminal.

For on-airport Reserved Parking, you can book through the Port of Seattle's official parking page. General Parking does not require advance reservation — you pay on exit — but long-term stays of 30+ days in the public garage should be confirmed with the Port to avoid any holds on your vehicle.

How Does SEA On-Site Parking Compare to Off-Site Lots for a Full Month?

The core trade-off is convenience vs. cost. On-site General Parking puts you steps from the terminal skybridge. Off-site lots add a free shuttle ride — typically 3–10 minutes — but cut your costs by up to 39% compared to on-airport rates.

• Walk to terminal: On-site garage via skybridge (2–5 min walk) vs. off-site shuttle (3–10 min ride + walk)
• 30-day cost: On-site General ~$637 vs. cheapest off-site ~$389
• Covered parking: On-site garage is fully covered; most off-site options are uncovered (exceptions: MasterPark Garage and WallyPark Premier Garage)
• EV charging: On-site garage has 48 free stations; MasterPark Lot A and MasterPark Garage also offer EV charging via Juicer; WallyPark Premier Garage has EV charging too
• Security: Both on-site and major off-site lots have 24/7 security and surveillance cameras
• Advance booking required: Reserved Parking (Floor 4) requires advance booking; General Parking and most off-site lots allow drive-up, though booking ahead secures your rate

For most travelers leaving a car for a full month, the off-site lots offer better value without a meaningful sacrifice in security or convenience. The shuttle ride is a minor tradeoff for saving $200–$700 over 30 days.

What Happens If You Leave Your Car at SEA Airport for More Than 30 Days?

Leaving a vehicle in SEA's on-airport garage beyond 30 days without prior arrangement can trigger a vehicle hold. The Port of Seattle monitors long-term vehicles in the public garage. If your car sits beyond a standard extended stay without communication, airport security may flag it and attempt to contact the registered owner.

The safest approach: contact the Port of Seattle directly before your trip if you expect to exceed 30 days. Their parking operations team can note your vehicle details and expected return date. This prevents your car from being flagged as abandoned. You can reach parking operations through the official SEA parking page.

For off-site lots, the policy is simpler. Your reservation covers the dates you booked. If your return is delayed, call the lot directly and extend your reservation. Most major SEA-area lots — including Jiffy, MasterPark, Doug Fox, and WallyPark — offer free cancellation and flexible modification. Always book with free cancellation when your return date is uncertain.

Also keep in mind: Waze live traffic and real-time flight tracking apps can help you coordinate your return pickup logistics when shuttle timing matters. If your flight lands late, your car and shuttle are still waiting — that's a genuine advantage of off-site lots over rideshare for long trips.

Which Off-Site Seattle Airport Parking Lots Offer Monthly Rates?

None of the eight verified off-site lots near SEA publish a dedicated flat monthly rate. All bill by the day, making the effective monthly cost a function of your exact night count and the daily rate you lock in at booking.

That said, booking further in advance often yields lower per-day rates through early-bird pricing. Based on our analysis of Triply listings for SEA, travelers booking 2–4 weeks ahead typically see the best available rates. Waiting until the week before departure — especially in summer or around the 2026 FIFA World Cup matches in Seattle — risks higher rates and reduced availability.

Here's a quick summary of which lots offer the best combination of price, amenities, and shuttle service for a 30-day stay:

• Best price: Jiffy Airport Parking and ShuttlePark2 ($12.95/day, ~$389/month)
• Fastest shuttle: Doug Fox Airport Parking (~3 minutes to terminal)
• Best covered option: MasterPark Garage ($17.99/day, valet available, EV charging)
• Best amenities: WallyPark Premier Garage (free WiFi, coffee, water, covered, EV charging)
• Best rewards program: MasterPark Lot A or MasterPark Garage (loyalty points on stays)

Is Long-Term Airport Parking Safe for a Month-Long Trip?

Both on-airport and the major off-site lots near SEA are considered safe for month-long vehicle storage. The on-airport garage has ~13,000 spaces and is managed directly by the Port of Seattle, with 24/7 staffing and security patrols. It's one of the most secure parking environments at any Pacific Northwest airport.

Off-site lots vary, but all eight verified lots in Triply's SEA database include 24/7 security and surveillance cameras. Fenced and gated lots — including Jiffy Airport Parking, Doug Fox Airport Parking, and Ajax Parking R Us — add a physical security layer. Doug Fox and MasterPark have operated near SEA for decades and carry strong long-term reputations among frequent flyers.

A few practical steps reduce risk further for any month-long stay:

• Remove valuables from the vehicle before you leave
• Take a photo of your car's condition and parking spot location at drop-off
• Keep your reservation confirmation and the lot's direct phone number saved
• Choose a lot with a free cancellation policy in case your return date shifts

Note that personal auto insurance typically covers your parked vehicle regardless of location, but check your policy for any exclusions on long-term storage away from your primary address.
