SeaTac Airport Parking Booking: Full 2026 Guide

Back to Complete SEA Airport Parking Guide

SeaTac airport parking booking is the process of reserving a parking spot at Seattle-Tacoma International Airport, either in the official on-airport garage or at a nearby off-site lot, before you arrive. The four off-site lots Triply sells near SEA start at about $9/day, while the on-airport garage runs $37/day for General Parking and $47/day for Reserved Parking on Floor 4. Booking an off-site lot ahead locks in your rate and holds your space; on-airport General Parking can't be reserved, so it's drive-up only.

• Off-site lots on Triply run from about $9/day (Motel 6) to about $19/day (Seattle Airport Marriott), about 60% to 80% less than on-airport Reserved Parking at $47/day.
• Triply sells four off-site lots near SEA, listed 0.9 to 2.6 miles from the airport. Fox Parking SeaTac and the Seattle Airport Marriott run free 24/7 shuttles; Motel 6's free shuttle runs 7 AM to 10 PM only.
• The Seattle Airport Marriott is the closest of the four, listed 0.9 miles out, with a shuttle every 15 minutes.
• The on-airport garage has more than 11,000 spaces, and Reserved Parking (Floor 4) can only be booked through the Port's ReserveSEA site.
• Bookings on Triply come with free cancellation with a full refund up to 24 hours before check-in.
• SEA's parking garage remains fully operational during ongoing SAMP construction as of 2026.

How Much Does SeaTac Airport Parking Cost in 2026?

SEA parking rates in 2026 vary significantly by location and lot type. Per the Port of Seattle's published rates (checked October 2026, taxes and fees included), on-airport General Parking costs $8/hour up to a $37/day maximum ($222/week), and Reserved Parking on Floor 4 runs $47/day. The four off-site lots Triply sells are considerably cheaper, at about $9 to $19/day before tax. Off-site rates are for a 7-day stay booked ahead and change by date.

What Are the Best SeaTac Airport Parking Options for Your Trip?

The best option depends on your trip length, budget, and whether you need covered parking. Here's how to match your needs to the right lot.

Short Trip (1-2 Days): On-Airport Convenience

For a quick overnight trip, the on-airport garage is hard to beat. The skybridge connects directly to the main terminal between Concourses B and C. No shuttle wait, no extra steps. General Parking maxes out at $37/day: not cheap, but reasonable for short stays.

Long Trip (3+ Days): Off-Airport Saves Real Money

For a 7-day trip, off-site lots save real money compared to on-airport General Parking at its $222 weekly rate: about $66 at Motel 6 or about $83 at Fox Parking SeaTac (before tax). Fox Parking SeaTac and the Seattle Airport Marriott run free 24/7 shuttles; Motel 6's shuttle runs 7 AM to 10 PM only, so it suits daytime flights. The savings grow on longer trips.

Need Covered Parking?

• SEA on-airport garage: $37/day General Parking or $47/day Reserved Parking on Floor 4, with skybridge access
• None of the four off-site lots Triply sells near SEA is described as covered: Fox Parking SeaTac is outdoor self-parking and the Seattle Airport Marriott uses a gated outdoor lot

Shuttle Frequency at Each Lot

• Seattle Airport Marriott: free, 24/7, every 15 minutes (closest of the four, listed 0.9 mi)
• Fox Parking SeaTac: free, 24/7, every 15-20 minutes or on demand
• Evods Parking at Spark by Hilton: 24/7, every 30 minutes, on the hour and half hour
• Motel 6: free, once an hour on the hour, 7 AM to 10 PM only

How Do You Book SeaTac Airport Parking Online — Step by Step?

Booking SeaTac airport parking online takes under five minutes. Here's the exact process using Triply.

1. Go to the Triply SEA search page. Visit triplypro.com/search?airport=SEA and enter your arrival date, departure date, and the airport code SEA.
2. Compare available lots side by side. Triply shows rates, shuttle details, amenities, and distance from the airport for each lot in one view.
3. Select your lot and click Reserve. Choose the lot that matches your budget and flight times. Bookings come with free cancellation with a full refund up to 24 hours before check-in.
4. Enter your vehicle and contact details. You'll need your license plate number, email address, and payment info.
5. Receive your booking confirmation. You'll get a confirmation email with your reservation details.
6. On departure day, follow the lot's check-in steps. At Motel 6 you get a parking tag at the front desk; at Fox Parking SeaTac you check in at the office; at Evods a valet attendant takes your keys; at the Seattle Airport Marriott you pull a gate ticket and keep it with your confirmation for validation. On-airport Reserved Parking (booked with the Port) uses a QR code scanned at the garage entry gate.

On-airport Reserved Parking is not sold on Triply: you book it directly through the Port of Seattle's official parking page (ReserveSEA). The QR code they send grants direct entry at the Floor 4 gate: no ticket to grab, no pay station on the way out.

How Far Are Off-Airport Parking Lots from the SEA Terminal?

The four off-site lots Triply sells are listed 0.9 to 2.6 miles from SEA. Shuttle hours differ: Fox Parking SeaTac, Evods and the Seattle Airport Marriott run 24/7, while Motel 6 runs 7 AM to 10 PM only. On return, each lot picks up at its own spot: the Marriott at garage Level 3, Courtesy Vehicle Island 1B or 3B; Fox Parking SeaTac at Courtesy Vehicle Island 1 or 3 (via any skybridge); Evods at location 3B; and Motel 6 at Ground Transportation Island 3A, after you call the motel.

One note for 2026 travelers: the SEA Gateway Project — roadway and terminal frontage improvements — is targeting completion in 2026. Some temporary detours near the terminal frontage are possible. Budget an extra 10 minutes during construction when driving to off-airport lots and check Waze live traffic map for real-time road conditions before you leave home.

Can You Cancel Your SeaTac Parking Reservation?

Off-site bookings on Triply come with free cancellation with a full refund up to 24 hours before check-in. Inside 24 hours, the booking can't be cancelled online. Bookings can't be modified: if your dates change, cancel more than 24 hours ahead and book again.

On-airport Reserved Parking is booked through the Port of Seattle's ReserveSEA site, and the Port lets you modify or cancel those reservations up to 6 hours before entry. That's the Port's own system, separate from Triply bookings. Either way, booking early carries little risk.

Which SeaTac Parking Lots Offer EV Charging, Covered Parking, or Valet?

EV drivers, road warriors who want weather protection, and travelers who prefer valet all have specific options at SEA. Here's what's available.

EV Charging

• SEA on-airport garage: 94 free Level 2 charging stalls for parking customers (64 on Floor 7 in General Parking, 30 on Floor 4 in Reserved Parking), first come, first served and not reservable, per the Port of Seattle
• Fox Parking SeaTac: mentions a separate Valet + Charging rate; charging is not part of its standard rate

Covered Parking

• SEA on-airport garage: General Parking $37/day, Reserved Parking $47/day
• None of the four off-site lots Triply sells near SEA is described as covered

Valet Service

• Evods Parking at Spark by Hilton: valet-based (staff park your car), about $16/day, 3-day minimum booking
• Fox Parking SeaTac: outdoor self-parking with valet assistance available, about $12/day

If you drive an EV, the on-airport garage's free charging stalls are first come, first served, so a stall isn't guaranteed. For more on EV charging options, the ChargePoint app for EV drivers can help you locate charging stations near SEA before and after your trip.

How Far in Advance Should You Book SeaTac Airport Parking?

For most travel dates, booking 1-2 weeks in advance is enough to secure your preferred lot and rate. But for peak periods, you'll want to move faster.

Peak Travel Booking Windows

• Summer (June-August): Book 3-4 weeks ahead. SEA is the largest airport in the Pacific Northwest and sees heavy summer demand.
• Thanksgiving and Christmas/New Year's: Book 4-6 weeks ahead. On-airport Reserved Parking sells out first, and off-airport lots fill next.
• Major events in Seattle: Book as early as possible. Seattle's 2026 FIFA World Cup matches showed how quickly demand spikes around big events.
• Off-peak travel (January-March, September-October): Booking 3-7 days in advance is usually fine.

The Port's ReserveSEA site takes on-airport Reserved Parking bookings up to 120 days in advance. Off-site bookings on Triply come with free cancellation with a full refund up to 24 hours before check-in, so booking early carries little risk: if your plans change in time, cancel and book again.

Is Off-Airport Parking at SeaTac Safe and Secure?

The four off-site lots Triply sells near SEA each list their own security setup. Here's how they compare.

If security is a top priority, Evods Parking at Spark by Hilton lists the most complete set of features, though it's a valet lot, so staff hold your keys. If you'd rather park yourself, Fox Parking SeaTac offers outdoor self-parking at a facility staffed 24/7, and the Seattle Airport Marriott has you park in its gated, well-lit lot.

For a full breakdown of each lot's amenities and how they compare on price, see our Seattle airport parking spot guide covering all 2026 rates and lot features.

Tips for a Smooth SeaTac Airport Parking Booking Experience

A few practical details make a big difference on travel day.

• Plan your return pickup. At Motel 6 you call the motel from Ground Transportation Island 3A after collecting bags; at Fox Parking SeaTac you request the shuttle with the E-Parking link sent at check-in. The Marriott shuttle runs every 15 minutes and Evods every 30 minutes, so allow time for the wait.
• Save your confirmation email offline. Cell service near some lots can be spotty. Screenshot your booking details before you arrive.
• Know your TSA lane. If you have TSA PreCheck, budget less time at security and more flexibility on when you arrive. Without it, add 30-45 minutes to your airport arrival window.
• Check construction alerts. SEA's Gateway Project roadway improvements are ongoing in 2026. The terminal frontage may have temporary detours: give yourself extra buffer if driving during peak hours.
• Use the Cell Phone Lot if picking someone up. It's free and located off the Airport Expressway, south of the terminal. Don't pay for parking just to wait for an arrival.
• Check shuttle hours for early or late flights. Motel 6's shuttle runs 7 AM to 10 PM only; for an early morning flight or a late-night return, pick a lot with a 24/7 shuttle.
