How Much Does SeaTac Airport Parking Cost in 2026?

On-airport General Parking at SEA costs $8/hour, capped at $37/day and $222/week, per the Port of Seattle's official parking page (checked October 2026; airport rates include taxes and fees). Reserved Parking on Floor 4 of the garage costs $47/day, with no posted weekly rate (7 days comes to $329). The four off-site lots Triply sells run from about $9/day to about $19/day; these rates are for a 7-day stay booked ahead, shown before tax, and change by date.

The SEA parking garage has more than 11,000 spaces and connects to all concourses via a single skybridge between Concourses B and C. The Cell Phone Lot near the Off Airport Expressway is completely free, ideal if you're waiting to pick someone up. On-airport rates below come from the Port of Seattle; off-site rates are what Triply shows for each lot.

A week-long trip shows the savings clearly. General Parking on-airport costs $222/week, while Motel 6 works out to roughly $66 for the same 7 days (before tax), a saving of about $156. Fox Parking SeaTac, with a free 24/7 shuttle, comes to about $83. For longer trips, that gap grows even wider. For details on extended stays, see our guide to Seattle airport parking for 1 week.

What Are the Best Off-Airport Parking Lots Near SeaTac for Low Rates?

Triply sells four off-site lots near SEA, starting at about $9/day, roughly 49% to 75% below the on-airport daily maximum of $37. Shuttle hours, valet versus self-park, and minimum stays differ, so check each lot below. Every booking on Triply comes with free cancellation with a full refund up to 24 hours before check-in. Here they are, ranked by price.

• Motel 6, about $9/day: 18900 47th Avenue South, SeaTac, listed 2 miles from SEA. Fully fenced lot monitored by security cameras; check in at the front desk for a parking tag. The free shuttle runs 7 AM to 10 PM, once an hour on the hour, with no shuttle from 10 PM to 7 AM.
• Fox Parking SeaTac, about $12/day: 20841 International Blvd, listed 2.6 miles away. Outdoor self-parking with valet assistance available, staffed 24/7. Free shuttle 24/7, every 15-20 minutes or on demand.
• Evods Parking at Spark by Hilton, about $16/day: 18220 International Blvd, listed 1 mile away. Valet-based (staff park your car), with a 3-day minimum booking. Fenced with controlled access and 24/7 video surveillance. Shuttle 24/7, every 30 minutes on the hour and half hour.
• Seattle Airport Marriott, about $19/day: 3201 South 176th Street, listed 0.9 miles away, the closest of the four. Gated, well-lit outdoor lot with onsite security. Free 24/7 shuttle every 15 minutes. Standard vehicles only.

If you want the shortest drive to the terminal, the Seattle Airport Marriott at about $19/day is the closest lot Triply sells and still costs about $18/day less than General Parking's $37 daily maximum. For a detailed breakdown of lot rates including hourly options, check the SeaTac airport parking lot rates guide.

On-Airport vs. Off-Airport Parking at SeaTac: Which Saves You More?

Off-airport parking saves most travelers significantly more money than the on-airport garage, especially for trips longer than two days. Here's a direct comparison based on official Port of Seattle rates (checked October 2026) and the off-site lots Triply sells.

• Convenience: On-airport parking wins. You walk directly to the terminal via skybridge, with no shuttle wait.
• Price (daily): Off-airport wins, at about $9/day at Motel 6 vs. $37/day on-airport, a saving of about $28/day.
• Price (weekly): Off-airport wins, at about $66 at Motel 6 or about $83 at Fox Parking SeaTac vs. $222/week on-airport.
• Covered parking: None of the four off-site lots Triply sells is described as covered.
• Security: The off-site lots list their own setups: Motel 6 is fenced with cameras, Evods is fenced with controlled access and 24/7 video surveillance, the Marriott lot is gated with onsite security, and Fox is staffed 24/7.
• Shuttle time: On-airport wins, with zero shuttle time on-site. Off-site, the Seattle Airport Marriott (0.9 miles) is the closest lot Triply sells.
• EV charging: On-airport offers 94 free Level 2 charging stalls, first come, first served.

The verdict: For trips of three days or more, off-airport parking almost always saves you money, even after factoring in the shuttle. For a quick overnight or same-day trip, the on-airport garage's walk-in convenience may be worth the premium. Travelers planning a two-week trip will save roughly $280 or more by choosing Motel 6 or Fox Parking SeaTac over two weeks of on-airport General Parking ($444 at the weekly rate). For more detail on extended-stay savings, our Seattle airport parking for 2 weeks guide breaks down the numbers in full.

How Do SeaTac Airport Parking Shuttles Work?

Shuttles differ by lot near SEA. Fox Parking SeaTac and the Seattle Airport Marriott run free 24/7 shuttles, Evods Parking at Spark by Hilton runs every 30 minutes around the clock, and Motel 6 runs only from 7 AM to 10 PM. Return pickups are at the courtesy vehicle islands reached from the airport parking garage.

Shuttle frequency varies by lot:

• Seattle Airport Marriott: Free, 24/7, every 15 minutes from the hotel front entrance. Between 1 AM and 2 AM, call the hotel at 206-241-2000.
• Fox Parking SeaTac: Free, 24/7, every 15-20 minutes or on demand. Dispatch: 206-589-7526.
• Evods Parking at Spark by Hilton: 24/7, every 30 minutes, on the hour and half hour.
• Motel 6: Free, 7 AM to 10 PM only, once an hour on the hour. No shuttle from 10 PM to 7 AM, so it does not suit very early flights or late-night arrivals.

On your return, head to your lot's pickup spot: the Seattle Airport Marriott at Island 1B or 3B on Level 3 of the parking garage, Fox Parking SeaTac at Courtesy Vehicle Island 1 or 3 (request pickup with the E-Parking link sent at check-in), Evods at location 3B, and Motel 6 at Ground Transportation Island 3A (call the motel at (206) 248-9000). Build in an extra 20-30 minutes before your arrival, especially during peak travel times like summer or holidays.

Note: SEA's SEA Gateway Project — roadway and terminal frontage improvements — is targeting completion in 2026. Some temporary detours around the terminal frontage may add a few minutes to shuttle drop-off. The parking garage itself remains fully operational throughout construction, according to the Port of Seattle's Sustainable Airport Master Plan.

How Can You Reserve SeaTac Airport Parking at the Best Rate?

Booking online in advance is the simplest way to secure the seatac airport parking best rates. It holds your space at the rate you booked, and reserving guarantees your spot during peak travel periods, when lots fill up fast.

Here's how to book in four steps:

1. Compare lots on Triply: Visit Triply's SEA parking search to see the four off-site lots side by side, from about $9/day.
2. Enter your travel dates: Input your departure and return dates to get accurate daily and total pricing for your trip length.
3. Choose your lot: Pick based on price, distance, shuttle hours, valet or self-park, and minimum stay (Evods has a 3-day minimum).
4. Complete your booking: Pay online and save your confirmation. Bookings come with free cancellation with a full refund up to 24 hours before check-in.

For a full step-by-step walkthrough including what to do if you return early or arrive late, see the SeaTac airport parking reservation online guide. During busy periods, book as early as your plans allow, since lots can sell out.

Is Long-Term Parking at SeaTac Worth It — or Should You Go Off-Site?

For trips of a week or longer, off-site parking is almost always worth it over staying on-airport. The on-airport weekly rate of $222 compares to roughly $66 at Motel 6 or $83 at Fox Parking SeaTac for the same 7-day period, a saving of about $139 to $156 per week before tax.

For a 14-day trip, that saving roughly doubles. Two weeks of on-airport General Parking at the weekly rate comes to $444. At about $9/day at Motel 6, the same trip costs about $132, and about $165 at Fox Parking SeaTac: a difference of roughly $280 to $310. The shuttle ride is an easy trade-off for that kind of saving.

Long-term travelers should also consider shuttle hours. Fox Parking SeaTac (every 15-20 minutes or on demand) and the Seattle Airport Marriott (every 15 minutes) run around the clock, so you don't plan around a timetable. Motel 6's shuttle stops at 10 PM, so check your return flight time before booking it. For trips of 30 days or more in the on-airport garage, the Port asks you to reserve online or arrange it with the Public Parking Office at (206) 787-4069. For full monthly parking options and extended-stay planning, check the Seattle airport parking for a month guide.

SeaTac Parking Tips: How to Save Money During Peak Travel Season

Peak travel periods at SEA — including summer, Thanksgiving, Christmas, and the New Year — can push off-site lot availability to zero if you wait too long. Seattle is hosting 2026 FIFA World Cup matches, making summer 2026 an unusually high-demand period for parking near the airport. The tips below are based on our analysis of seasonal parking trends at SEA.

• Book 1-2 weeks ahead during peak season. Lots fill up fast around major holidays and during summer. Don't wait until the week of your flight.
• Use free cancellation to your advantage. Triply bookings come with free cancellation with a full refund up to 24 hours before check-in, so you can book early and cancel if your plans fall through.
• Check real-time traffic on Waze before you drive. SEA Gateway Project construction can cause detours around the terminal frontage in 2026. Factor in 10-15 extra minutes during peak hours.
• Avoid Reserved Parking unless you need it. At $47/day, Reserved Parking costs $10/day more than General Parking, and it must be booked on the Port's ReserveSEA site at least 6 hours ahead.
• Fly with TSA PreCheck. While this doesn't affect your parking cost, pairing a 24/7 shuttle lot with TSA PreCheck can cut your pre-flight arrival time.
• Try the Cell Phone Lot for quick pickups. If you're just dropping someone off or picking up a traveler, the Cell Phone Lot at the Off Airport Expressway is completely free.
• Match the lot to your flight times. Motel 6 is the cheapest, but its shuttle runs only 7 AM to 10 PM; for very early or late flights, Fox Parking SeaTac or the Seattle Airport Marriott run 24/7.

Off-site, the Seattle Airport Marriott lot takes standard vehicles only. For a complete breakdown of vehicle height limits, see the Seattle airport parking height limit guide.
