Seattle Airport 1 Month Parking: Full 2026 Cost Guide

Back to Complete SEA Airport Parking Guide

Seattle Airport 1 month parking is the practice of leaving your vehicle at or near Seattle-Tacoma International Airport (SEA) for an extended 30-day period, using either the on-airport garage's daily rate, the Port of Seattle's Passport Monthly Parking program, or an off-site lot that prices stays by the day. For a full 30 days, costs range from roughly $388/month at the cheapest off-airport lots to $960/day at on-airport General Parking — making the option you choose a very large financial decision.

• On-airport General Parking costs $32/day — that's $960 for 30 days (per Port of Seattle, verified May 2026).
• Passport Monthly Parking is a flat-rate program offered by the Port of Seattle — around $375/month based on available data, with Sky Bridge access and unlimited in/out privileges.
• Off-airport lots start at $12.95/day, which works out to roughly $388–$568/month across the 8 verified lots near SEA.
• All major off-site lots include free 24/7 shuttle service to and from the terminal.
• Booking in advance is critical — monthly spots fill fast, especially before summer and major events like the 2026 FIFA World Cup in Seattle.
• Parking for more than 30 days without prior arrangements can result in your vehicle being towed. Contact SEA parking operations directly if you need an extended stay.

How Much Does 1 Month of Parking at Seattle Airport Cost?

The total 30-day cost depends entirely on which option you use. On-airport General Parking runs $32/day with a $149/week cap (per the Port of Seattle). Over four weeks, that weekly cap means you'd pay roughly $596 for 28 days — still significantly more than off-airport alternatives. Reserved Parking on Floor 4 costs $39/day, reaching over $1,170 for a month.

Off-airport lots offer the most realistic pricing for month-long stays. Jiffy Airport Parking and ShuttlePark2 both start at $12.95/day, putting a 30-day stay at roughly $388. MasterPark Lot A comes in at $13.99/day ($419/month). Covered garage options like MasterPark Garage ($17.99/day) and WallyPark Premier Garage ($18.95/day) run $539–$568 for 30 days.

The savings are significant. Parking at Jiffy Airport Parking for 30 days saves you roughly $572 compared to on-airport General Parking — that's nearly 60% less. For a full breakdown of daily and weekly rates, see our guide to Seattle Airport parking rates per day.

What Is Passport Monthly Parking at SEA and How Does It Work?

Passport Monthly Parking is a subscription-style program managed by the Port of Seattle that gives frequent travelers a dedicated monthly parking pass for the SEA Airport garage. Based on available data, the rate is around $375/month — a flat fee that undercuts the standard daily rate significantly. This is the only on-airport option that gets close to off-site lot pricing for monthly stays.

Passport Monthly holders reportedly receive Sky Bridge access, letting them walk directly from the parking garage into the terminal. This is a real convenience benefit over off-site lots, which require a shuttle ride. The program also allows unlimited in/out access, which matters if you're a frequent flyer returning home mid-trip. Availability is limited, so spots can fill quickly during peak travel periods.

To enroll, contact the Port of Seattle's parking office directly. The SEA parking information page at portseattle.org is the official source for current program details, pricing, and enrollment. Rates and availability are subject to change, so verify before booking.

How Do Off-Airport Lots Compare for 30-Day Seattle Airport Parking?

Off-airport lots are the most cost-effective option for most travelers doing 1-month parking at Seattle Airport. All eight verified lots near SEA include free 24/7 shuttle service — a feature that removes the main downside of parking farther away. Shuttle rides range from 3 minutes (Doug Fox Airport Parking) to 7-10 minutes (ShuttlePark2), depending on the lot's distance from the terminal.

Here's how the top contenders compare for extended stays:

• Jiffy Airport Parking ($12.95/day): Attendants meet you at your car. Fenced, well-lit, with surveillance cameras. One of the best value options for 30 days.
• ShuttlePark2 ($12.95/day): Self-park and lock. Shuttle drops you directly at the 3rd floor of the parking garage. Open 365 days.
• MasterPark Lot A ($13.99/day): On-demand shuttle using eco-friendly yellow buses. Offers EV charging via Juicer and a rewards program — great for repeat monthly parkers.
• Doug Fox Airport Parking ($14.95/day): The oldest and closest off-site lot to SEA. Shuttle runs 24/7 with a ~3-minute ride. Fenced, gated, and well-lit.
• MasterPark Garage ($17.99/day): Covered parking with valet service. Best pick if you want weather protection and don't mind paying slightly more.

For travelers who want the security of covered parking without paying on-airport prices, the MasterPark Garage and WallyPark Premier Garage are strong alternatives. Both include EV charging — useful if you drive an electric vehicle. You can also explore SeaTac airport parking with shuttle service for a deeper comparison of shuttle reliability across lots.

How Do You Book Extended Stay Parking at SeaTac for Over 30 Days?

Booking a 30-day stay is straightforward at most off-airport lots — just select your dates during checkout and pay the daily rate multiplied by your stay. Most platforms cap reservations at 30 days per booking, so stays longer than 30 days may require a second booking or direct contact with the lot.

For on-airport stays exceeding 30 days, the Port of Seattle requires you to make special arrangements in advance. Leaving your vehicle in the SEA garage past 30 days without prior authorization can result in your car being towed at your expense. Contact the Port of Seattle parking operations team directly through the SEA parking page before your trip if you need more than 30 days.

For off-airport lots, the safest approach is to call the lot directly and ask about their extended-stay policy. Most major lots — including MasterPark, WallyPark, and Doug Fox — have staff available 24/7 and can accommodate longer reservations with advance notice. Always get confirmation in writing.

Which Seattle Airport Parking Option Saves You the Most Money for a Full Month?

The cheapest verified option is Jiffy Airport Parking or ShuttlePark2, both at $12.95/day — or roughly $388 for 30 days. That's a savings of over $572 compared to on-airport General Parking at $32/day. Even the Passport Monthly Parking program at around $375/month is slightly cheaper than the best off-site lots when you factor in the convenience of walking directly to the terminal.

The math changes if you need covered parking. The MasterPark Garage at $17.99/day is 44% cheaper than on-airport General Parking while still offering a roof over your car. WallyPark Premier Garage at $18.95/day adds free WiFi and coffee — small perks that add up over a month-long stay.

For frequent flyers who park monthly, the MasterPark Rewards Program can deliver additional savings over time. If you're comparing multiple trips and total annual costs, our Seattle Airport long-term parking guide breaks down the best strategies for repeat travelers.

What Are the Shuttle and Access Options for Long-Term SeaTac Parking?

Every major off-airport lot near SEA runs a free, 24/7 shuttle service. Shuttles typically drop off and pick up at the 3rd floor Courtesy Vehicle area of the on-airport parking garage, which gives you covered walk access to the terminal via the skybridge. Doug Fox has the fastest ride at ~3 minutes. ShuttlePark2 and Jiffy run 6-10 minutes depending on traffic on International Boulevard (SR-99).

Shuttle frequency matters for a month-long stay. WallyPark runs shuttles every 15-20 minutes, while MasterPark and Doug Fox offer on-demand service — meaning you call or signal and the shuttle comes to you, rather than waiting for a fixed schedule. On-demand is the better experience for early morning or late-night returns.

One note for 2026: the SEA Gateway Project is improving roadway flow at the terminal frontage, and the new Ground Transportation Center (part of the Sustainable Airport Master Plan) is also under development. These changes are designed to improve shuttle and bus access. The parking garage itself remains fully operational throughout construction.

Tips for Securing Monthly Seattle Airport Parking in Advance

Month-long parking spots at SEA fill up faster than most travelers expect — especially during summer (June–August) and around major events. With Seattle hosting 2026 FIFA World Cup matches, demand near the airport is unusually high this year. Book as early as possible.

• Reserve online — Most lots let you pre-book through their own site or comparison platforms. Prepaid rates are often lower than drive-up prices.
• Look for free cancellation — All eight verified off-site lots offer free cancellation, so booking early carries no risk.
• Check for promo codes — Discount codes can shave 10-20% off your total. See our SeaTac airport parking discount codes guide for current deals.
• Use a rewards program — MasterPark's rewards program is worth signing up for if you park monthly. Points accumulate across visits.
• Confirm your shuttle hours — Call your lot directly to confirm 24/7 shuttle availability matches your flight times, especially for red-eye departures or early morning arrivals.
• Check traffic before driving — I-5 near SeaTac can back up significantly. Use the Waze live traffic map to plan your drive-in time and avoid missing your shuttle window.

If you're driving a large vehicle, confirm height clearance before booking a covered garage. For standard-height vehicles, all options in the table above are accessible without issue.
