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, 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 $282 at the lowest-priced off-site lot Triply sells to about $962 at on-airport General Parking, making the option you choose a very large financial decision.

• On-airport General Parking costs $37/day or $222/week, about $962 for 30 days (per the Port of Seattle, checked October 2026).
• Passport Monthly Parking is a program offered by the Port of Seattle, with Sky Bridge access; confirm current pricing with the Port's Public Parking Office.
• The four off-site lots Triply sells start at about $9/day, roughly $282 to $566 for 30 days before tax.
• Fox Parking SeaTac and the Seattle Airport Marriott run free 24/7 shuttles; Evods Parking at Spark by Hilton runs a 24/7 shuttle every 30 minutes; Motel 6's shuttle runs 7 AM to 10 PM only.
• Booking in advance is critical: monthly spots fill fast, especially before summer and major events.
• Parking 30 days or more on-airport without prior arrangements can result in your vehicle being towed. Reserve online or contact the Port's Public Parking Office at (206) 787-4069.

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 $37/day with a $222 weekly rate (per the Port of Seattle, taxes and fees included). Four weeks at the weekly rate come to $888 for 28 days, or about $962 for 30 days, still far more than off-airport alternatives. Reserved Parking on Floor 4 costs $47/day, reaching about $1,410 for a month.

Off-airport lots offer the most realistic pricing for month-long stays. At Motel 6, about $9/day, a 30-day stay comes to roughly $282. Fox Parking SeaTac at about $12/day is roughly $355, Evods Parking at Spark by Hilton at about $16/day roughly $469, and the Seattle Airport Marriott at about $19/day roughly $566. These are estimates before tax: rates are for a 7-day stay booked ahead and change by date, so check your exact 30-day price on Triply.

Compare SEA 1-month parking at the off-site lots Triply sells, from about $9/day, and book your spot.

The savings are significant. Parking at Motel 6 for 30 days costs roughly $680 less than on-airport General Parking, and Fox Parking SeaTac, with its 24/7 shuttle, about $607 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 monthly parking pass for the SEA Airport garage. Its price is not part of the Port's posted rates we checked in October 2026, so confirm the current rate and availability with the Port's Public Parking Office at (206) 787-4069 before you rely on it.

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. Triply sells four near SEA, listed 0.9 to 2.6 miles from the airport. Shuttle service differs by lot: Fox Parking SeaTac and the Seattle Airport Marriott run free 24/7 shuttles, Evods Parking at Spark by Hilton runs one 24/7 every 30 minutes, and Motel 6's free shuttle runs only 7 AM to 10 PM.

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

• Motel 6 (about $9/day): Fully fenced and monitored by security cameras. Check in at the front desk for a parking tag. Free shuttle with online purchase, 7 AM to 10 PM, once an hour on the hour; no shuttle from 10 PM to 7 AM.
• Fox Parking SeaTac (about $12/day): Outdoor self-parking with valet assistance available, staffed 24/7. Free shuttle 24/7, every 15-20 minutes or on demand. Listed 2.6 miles out.
• Evods Parking at Spark by Hilton (about $16/day): Valet-based, so staff park your car. Perimeter fencing, controlled access, 24/7 video surveillance and on-site staff. Shuttle 24/7 every 30 minutes; 3-day minimum booking.
• Seattle Airport Marriott (about $19/day): The closest lot Triply sells, listed 0.9 miles out. Gated, well-lit outdoor lot with onsite security. Free 24/7 shuttle every 15 minutes; standard vehicles only.

If you drive an electric vehicle, note that Fox Parking SeaTac offers a separate Valet + Charging rate, and the on-airport garage has 94 free Level 2 charging stalls for parking customers, first come, first served. You can also explore SeaTac airport parking with shuttle service for a deeper comparison of shuttle options across lots.

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

Booking a 30-day stay at the off-airport lots Triply sells works like any other booking: select your dates during checkout. The rate shown is a daily rate before tax, and the checkout total can add tax at some lots, so check the full price for your dates. For stays longer than 30 days, contact the lot directly before you book.

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 contact the lot directly and ask about their extended-stay policy. All four lots Triply sells near SEA list a 24/7 front desk. Always get confirmation in writing.

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

The lowest-priced option Triply sells is Motel 6 at about $9/day, or roughly $282 for 30 days. That's about $680 less than on-airport General Parking over a month. Its shuttle runs only 7 AM to 10 PM, so if you fly early or land late, Fox Parking SeaTac at about $12/day (roughly $355 for 30 days) is the lowest-priced lot Triply sells with a free 24/7 shuttle.

The math changes if you want the shortest shuttle ride. The Seattle Airport Marriott, listed 0.9 miles from the airport, costs about $19/day, about 49% less than on-airport General Parking per day, with a free 24/7 shuttle every 15 minutes. Evods Parking at Spark by Hilton, 1 mile out at about $16/day, is valet-based, so you hand over your keys and skip the search for a space.

For frequent flyers who park monthly, booking ahead and comparing dates can keep costs down. 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?

Each off-airport lot Triply sells runs its own shuttle and return pickup point. Fox Parking SeaTac picks up at Courtesy Vehicle Island 1 or 3 (reached via any skybridge); request your shuttle with the E-Parking link sent at check-in. The Seattle Airport Marriott picks up in the airport parking garage, Level 3, at Island 1B or 3B. Evods picks up at location 3B. Motel 6 picks up at Ground Transportation, Island 3A: call the motel at (206) 248-9000 after collecting your bags.

Shuttle frequency matters for a month-long stay. The Seattle Airport Marriott runs every 15 minutes around the clock (between 1 AM and 2 AM, call the hotel), Fox Parking SeaTac every 15-20 minutes or on demand, Evods every 30 minutes, and Motel 6 once an hour from 7 AM to 10 PM. For early morning or late-night returns, pick one of the 24/7 lots.

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: Book through the lot's own site or a comparison platform like Triply so your space is held for your dates.
• Look for free cancellation: bookings on Triply come with free cancellation with a full refund up to 24 hours before check-in, so booking early carries little risk.
• Check for promo codes: See our SeaTac airport parking discount codes guide for current deals.
• Check the minimum stay: Evods Parking at Spark by Hilton requires at least 3 days, which a month-long trip easily meets.
• Confirm your shuttle hours: Motel 6's shuttle runs only 7 AM to 10 PM, so match your lot to 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, check the rules before booking: the airport garage has a 6'10" height limit (over-height vehicles use a separate outdoor lot), and the Seattle Airport Marriott accepts standard vehicles only, with no large trucks, extended vans, trailers or oversized racks.
