What Is SeaTac Airport Off-Site Parking and How Does It Work?

Off-site parking is any private parking facility located near the airport but not owned or operated by the Port of Seattle. These lots sit close to SEA, run a shuttle to the terminal, and charge significantly less than the official on-airport garage.

Here's how the process works, step by step:

1. Book online: Reserve your spot through Triply. You'll receive a confirmation with the lot address and any entry instructions.
2. Drive to the lot: Follow GPS to the lot's address. Fox Parking SeaTac and Evods Parking at Spark by Hilton are on International Boulevard (SR-99); Seattle Airport Marriott is on South 176th Street and Motel 6 on 47th Avenue South.
3. Check in and park: At Motel 6, check in at the front desk for a parking tag. At Fox Parking SeaTac, park in a check-in space and check in at the office. Evods is valet-based, so staff park your car. At Seattle Airport Marriott, take a ticket at the gate and park in the lot behind the hotel.
4. Board the shuttle: Each lot runs its own shuttle to the terminal; hours differ by lot (see below).
5. Arrive at SEA: Shuttles drop off at the 3rd floor of the parking garage, in the Courtesy Vehicle area. From there, follow signs into the terminal.
6. Return pickup: After collecting your bags, go to your lot's pickup point. Motel 6: call (206) 248-9000 from Island 3A. Fox Parking SeaTac: request pickup with the E-Parking link and wait at Island 1 or 3. Evods: location 3B. Seattle Airport Marriott: Island 1B or 3B.

The entire process — parking, shuttle ride, and walking to check-in — typically adds 15–25 minutes to your airport arrival time. Build that buffer in when you plan your departure.

How Much Does SeaTac Off-Site Parking Cost? (Rates, Taxes & Fees Explained)

Off-site daily rates for the lots Triply sells at SEA range from about $9/day to about $19/day. That's a significant drop from the on-airport General Parking maximum of $37/day or Reserved Parking at $47/day.

Rates are for a 7-day stay booked ahead, shown before tax, and change by date (checked October 2026).

What Fees and Taxes Are Added to Off-Site Parking?

The rates above include booking fees but not tax. On Triply, Fox Parking SeaTac, Evods Parking at Spark by Hilton and Seattle Airport Marriott add tax at checkout, while the Motel 6 quote showed no tax. Here is what to expect at checkout:

• Booking fees: already included in the daily rate Triply shows
• Tax: added at checkout at Fox Parking SeaTac, Evods Parking at Spark by Hilton and Seattle Airport Marriott; none on the Motel 6 quote
• Billed days: a 7-night stay is billed as 8 days, so the total is more than 7 times the daily rate
• On-airport comparison: the Port of Seattle's garage rates already include taxes and fees

Always review the full checkout total before confirming, and note that a 7-night stay bills as 8 days. For 7-night stays checked in November 2026, Motel 6 came to $75.18, Fox Parking SeaTac to $103.58 (including $9.02 tax, for 2 and 9 November check-ins; $130.70 for 16 November), Evods Parking at Spark by Hilton to $137.49 and Seattle Airport Marriott to $165.48, both including tax. Triply shows the all-in price before you commit.

Which Off-Site Parking Lots Are Closest to Seattle-Tacoma International Airport?

Distance and shuttle frequency matter most when you're running tight on time. Here's how each lot Triply sells stacks up by listed distance from SEA:

• Seattle Airport Marriott: Listed 0.9 miles from SEA, the closest lot Triply sells. Free 24/7 shuttle every 15 minutes from the hotel front entrance; between 1 AM and 2 AM, call the hotel at 206-241-2000.
• Evods Parking at Spark by Hilton: Listed 1 mile from SEA, at 18220 International Blvd. Valet-based, with a 24/7 shuttle every 30 minutes on the hour and half hour.
• Motel 6: Listed 2 miles from SEA, at 18900 47th Avenue South. Free shuttle from 7 AM to 10 PM only, once an hour on the hour.
• Fox Parking SeaTac: Listed 2.6 miles from SEA, at 20841 International Blvd. Free 24/7 shuttle every 15-20 minutes or on demand.

Two of these lots, Fox Parking SeaTac and Evods Parking at Spark by Hilton, sit on International Boulevard (SR-99); Seattle Airport Marriott is on South 176th Street. If you're coming from Interstate 5, take State Route 518 west toward the airport and watch for lot signage. From SR-509 (West Seattle/Burien), merge onto the airport expressway and follow signs toward off-airport parking. For real-time traffic before your drive, check real-time traffic on Waze, especially useful during peak hours on I-5.

Once the shuttle drops you at SEA's 3rd-floor Courtesy Vehicle area, you enter the main terminal and follow signs to your concourse. A single skybridge connects to the terminal between Concourses B and C. From there, all concourses — A, B, C, D, North Satellite, and South Satellite — are accessible via the underground tunnel.

How Do Off-Site SeaTac Parking Shuttles Work — and How Long Do They Take?

Each off-site lot Triply sells at SEA runs its own shuttle. Fox Parking SeaTac, Seattle Airport Marriott and Motel 6 describe theirs as free; Evods Parking at Spark by Hilton runs a 24/7 shuttle every 30 minutes. Shuttle models vary by lot: some run on a fixed schedule, others on demand. For a comprehensive look at shuttle operations, our Seattle Airport Parking Shuttle guide covers lots and wait times in detail.

Shuttle Frequency by Lot

• Motel 6: 7 AM to 10 PM only, once an hour on the hour. No shuttle from 10 PM to 7 AM, so it doesn't suit early flights or late-night arrivals.
• Fox Parking SeaTac: 24/7, every 15-20 minutes or on demand. Call dispatch at 206-589-7526 if you need help.
• Evods Parking at Spark by Hilton: 24/7, every 30 minutes, on the hour and half hour. Accessible shuttle available on request.
• Seattle Airport Marriott: 24/7, every 15 minutes, no advance reservation needed. Between 1 AM and 2 AM, call the hotel at 206-241-2000.

Plan to add at least 10–15 minutes to your airport arrival time for an off-site lot, more at lots with less frequent shuttles (every 30 minutes at Evods, hourly at Motel 6). This covers parking, loading luggage, the shuttle ride, and the walk from the Courtesy Vehicle drop-off into the terminal. During peak periods, such as summer weekends, holidays, and the 2026 FIFA World Cup matches in Seattle, add an extra 10 minutes as shuttle demand increases.

On return, pickup works differently at each lot. Fox Parking SeaTac picks up on request through the E-Parking link sent at check-in; Motel 6 asks you to call (206) 248-9000 from Island 3A; Evods and Seattle Airport Marriott run on a schedule (every 30 and every 15 minutes) from 3B and Island 1B or 3B.

Is Off-Site Parking at SeaTac Safe and Secure?

Each of the four off-site lots Triply sells near SEA lists its own security setup. Here's what security looks like at each one:

• Motel 6: Fully fenced lot monitored by security cameras; 24/7 front desk.
• Fox Parking SeaTac: Staffed 24/7, so help is always on site.
• Evods Parking at Spark by Hilton: Perimeter fencing, controlled access points, 24/7 video surveillance, well-lit parking areas and continuous on-site staff.
• Seattle Airport Marriott: Gated, well-lit outdoor lot with onsite security. Keep your gate ticket and confirmation for validation.

Self-Park vs. Valet: Which Is Safer?

Self-park means you drive to a stall, lock your car, and keep your keys. No one else drives your vehicle. Valet means you hand your keys to an attendant who parks the car for you. Evods Parking at Spark by Hilton is valet-based, and Fox Parking SeaTac offers valet assistance alongside outdoor self-parking. Valet adds convenience but means a third party operates your vehicle.

For most travelers, self-park is the better choice. You maintain full control of your car, no one adjusts your mirrors or seats, and there's no risk of minor lot damage from another driver. Valet makes sense if you have a large vehicle and parking space is tight, or if mobility is a concern.

What About ADA and Accessible Parking?

If you need accessible parking, the on-airport garage has ADA stalls on Floor 5 (General Parking) and Floor 4 (Reserved Parking). Off-site, Evods Parking at Spark by Hilton offers handicap-accessible parking and an accessible shuttle on request, and Motel 6 lists wheelchair access; contact your chosen lot directly before booking if this is a requirement. For a full breakdown of ADA, EV, and specialty parking rules at SEA, the Seattle Airport Parking Information guide covers all accommodation options in detail.

Off-Site Parking vs. On-Site Garage vs. Rideshare: Which Is Cheapest for Your Trip?

The right option depends entirely on your trip length. Here's how the numbers compare, using on-airport rates checked in October 2026:

Rideshare estimates based on typical Seattle-to-SEA fares. Actual costs vary by surge pricing and pickup location. Off-site parking rates are before tax; on-airport rates include tax.

The pattern is clear: rideshare wins for 1-day trips, especially if you're traveling from downtown Seattle. For trips of about 3 to 7 days, the lower-priced off-site lots cost about the same as rideshare or less. A 7-day trip at Motel 6 costs about $66 before tax, or about $83 at Fox Parking SeaTac with a free 24/7 shuttle, versus $60–$80 round-trip rideshare that doesn't account for surge pricing, tips, or traffic delays. On much longer trips the parking total keeps growing, so compare both.

On-airport parking offers the convenience of no shuttle wait, but at $37/day, a week costs $222 at the weekly rate. The same week at Fox Parking SeaTac costs about $83 before tax, a saving of about $139, or 63%. At Motel 6 it's about $66, about 70% less.

For short-term trips of just a few hours, the on-site garage charges $8/hour up to the $37 daily maximum (2 hours is $16), which can work out cheaper than a full day at an off-site lot for a very short stay. For those quick trips, the Seattle Airport short-term parking guide breaks down exactly when hourly parking makes more sense.

How to Book SeaTac Off-Site Parking Online and Save the Most Money

Booking online ahead of your trip is the single best way to secure off-site parking at SEA. You hold your space at the rate you booked before busy periods sell out, with free cancellation and a full refund up to 24 hours before check-in.

Step-by-Step: How to Book

1. Compare rates across lots: Use Triply's SEA parking search to see the off-site lots Triply sells for your exact travel dates. Prices and availability update in real time.
2. Select your lot: Compare price, distance and shuttle hours, and read the shuttle details before confirming.
3. Enter your travel dates: Double-check your departure and return times. A 7-night stay can bill as 8 days.
4. Review the full total: Look for taxes and fees before checking out. The confirmation should show the all-in price.
5. Save your confirmation: Screenshot or print the reservation. You'll need the confirmation at the lot.
6. Arrive with buffer time: Plan to reach the lot at least 25–30 minutes before you need to be at your gate to account for parking, shuttle, and walking time, and more if your lot's shuttle runs every 30 minutes or hourly.

Tips for Getting the Lowest Rate

• Book early for peak dates: Summer weekends, holiday weekends, and the 2026 FIFA World Cup period in Seattle see higher demand, and lots can sell out. Book at least 1–2 weeks ahead.
• Look for promo codes: Check for a current discount code before you book.
• Match the lot to your flight times: Motel 6 is the lowest-priced lot, but its shuttle runs only 7 AM to 10 PM. For early flights or late arrivals, Fox Parking SeaTac and Seattle Airport Marriott run free 24/7 shuttles.
• Use free cancellation: Bookings on Triply come with free cancellation and a full refund up to 24 hours before check-in, so you can book early and cancel if your plans change.
• Check rates for your exact dates: Off-site rates change by date. Fox Parking SeaTac ranged from about $12 to about $15/day across November 2026 check-ins.

What About Construction and Traffic Delays in 2026?

The Port of Seattle's Sustainable Airport Master Plan (SAMP) is actively reshaping SEA in 2026. The SEA Gateway Project — roadway and terminal frontage improvements — targets completion in 2026 and will improve traffic flow. The C Concourse expansion ($260M) reaches substantial completion in Q2 2026. Some temporary construction zones may cause minor detours on approach roads. The parking garage remains fully operational throughout all projects. Check current road conditions before driving to any off-site lot, especially on weekends when construction activity may affect SR-99 or the airport expressway.

Ready to Park Smarter at SeaTac?

Seattle airport off-site parking delivers real savings, about $9 to $19/day versus $37/day on-site, without sacrificing much convenience. Pick the lot that fits your flight times: Fox Parking SeaTac and Seattle Airport Marriott run free 24/7 shuttles, while Motel 6's runs 7 AM to 10 PM. For a 7-day trip at the lowest-priced lot, you'll pay about $66 before tax compared to $222 for a week of General Parking. That's consistent, predictable savings every time you fly out of SEA.
