What Is Extra Car Airport Parking and Where Is It Located?

Extra Car Airport Parking is an independent off-site lot at 16300 International Blvd, SeaTac, WA 98188, sitting directly along State Route 99 (Pacific Highway South / International Boulevard). This road runs parallel to Interstate 5 and is the main commercial strip closest to the south end of the SEA terminal complex.

The lot sits roughly 2 miles north of Seattle-Tacoma International Airport's terminal entrance, placing it among the closer off-site options near SEA. Travelers arriving from I-5 northbound or southbound can take the SR-518 exit west and connect to SR-99 northbound. From SR-99 south, the lot is a short drive from the airport entrance. Use the Waze live traffic map before you leave — I-5 congestion near the airport can add 10–20 minutes to your drive time, especially during peak hours.

The address on International Blvd puts Extra Car in the same corridor as several other well-known lots, including Doug Fox Airport Parking (the closest off-site lot at just 3 minutes from SEA). Extra Car is easy to spot from the road and operates 24 hours a day, every day of the year.

How Much Does Extra Car Seattle Airport Parking Cost?

Extra Car's daily rate typically falls between $12 and $16 per day based on current booking platform data, though exact rates vary by date, demand, and whether you choose self-park or valet. No verified official weekly rate has been published directly by Extra Car, but travelers parking for 7+ days can expect proportional pricing in line with other lots on SR-99.

To put that in context: the SEA on-airport garage charges $32/day for General Parking and $39/day for Reserved Parking on Floor 4 (per the Port of Seattle, verified April 2026). At Extra Car's typical rate, you save roughly $16–$20 per day — or over $100 on a week-long trip — compared to parking on-site. For full Seattle Airport parking rate details, see our Seattle Airport parking rates breakdown for 2026.

Extra Car rate is an estimate based on third-party booking platforms as of April 2026. Always verify current pricing before booking.

How Does the Shuttle Service Work at Extra Car SeaTac?

The Extra Car shuttle runs 24 hours a day, 7 days a week, connecting the lot to Seattle-Tacoma International Airport. After parking your car, a shuttle picks you up at the lot and drops you off at the 3rd floor of the SEA parking garage — the standard Courtesy Vehicle area where all major off-site shuttles operate.

The shuttle ride from International Blvd to the terminal takes roughly 5–10 minutes depending on traffic and road conditions. On return, head to the 3rd floor Courtesy Vehicle area after collecting your bags. Look for the Extra Car signage or check with the shuttle coordinator. Most travelers wait under 10 minutes for pickup. Budget an extra 20–30 minutes total for the shuttle process when planning your airport arrival time.

For a detailed look at how all SEA off-site shuttles compare — including frequency, drop-off locations, and tips — read our SeaTac airport parking shuttle guide. The shuttle process at Extra Car follows the same general flow as other lots on International Blvd.

What Parking Options Does Extra Car Offer (Valet vs. Standard)?

Extra Car offers two main parking options: standard self-park and valet parking. Self-park is the base option — you drive to your spot, lock your car, and keep your keys. Valet service means an attendant parks your car for you upon drop-off and retrieves it when you return.

Valet typically costs more than self-park, though the exact price difference at Extra Car is not published officially. Based on comparable lots near SEA (such as MasterPark Garage, which charges $17.99/day for its valet-included option vs. $13.99 for standard), expect valet to add roughly $3–$5 per day. Valet is useful for larger vehicles, tight parking areas, or travelers who want a faster drop-off experience. It also removes any concern about fitting into standard parking spaces if you're driving an oversized vehicle or pickup truck.

How Do You Reserve and Check In at Extra Car Airport Parking?

Booking online in advance is the recommended approach at Extra Car. Online reservations lock in your rate and guarantee a spot — especially useful during peak periods like summer travel season and around the 2026 FIFA World Cup matches hosted in Seattle.

1. Book online via Extra Car's website or a comparison platform like Triply to compare current rates across all SEA lots.
2. Arrive at the lot at 16300 International Blvd and check in at the entrance booth. One source notes a 15-minute check-in window — arrive early enough to allow for this before your flight.
3. Choose self-park or valet at check-in and receive your parking ticket or confirmation.
4. Board the shuttle from the lot directly to the SEA terminal (3rd floor drop-off).
5. On return, call ahead or go directly to the Courtesy Vehicle area on the 3rd floor of the SEA garage and wait for the Extra Car shuttle.

Most off-site lots near SEA accept credit and debit cards (Visa, Mastercard, Amex, Discover). Cash payment availability at Extra Car has not been confirmed — contact the lot directly if you plan to pay cash. Free cancellation is standard practice at most SEA off-site lots; verify Extra Car's specific cancellation window when booking.

Is Extra Car Airport Parking Safe and Secure?

Extra Car operates a gated and fenced lot with 24/7 on-site staff and surveillance cameras throughout the property. The lot is well-lit, which matters for late-night drop-offs or early-morning returns. These are the same baseline security features offered by competing lots like Ajax Parking R Us and ShuttlePark2 along the International Blvd corridor.

Travelers using the self-park option keep their own keys throughout their trip — a feature many drivers prefer for peace of mind. With valet parking, your keys stay with the lot's attendants. Extra Car does not publish specific details about insurance coverage or liability for parked vehicles, which is typical for off-site lots. As a general rule, check your auto insurance policy to confirm off-site parking coverage before your trip.

The lot's location on International Boulevard (SR-99) is a well-trafficked commercial corridor with multiple businesses and constant vehicle movement, which contributes to passive security. It is not an isolated location.

How Does Extra Car Compare to Other SeaTac Off-Airport Parking Lots?

Extra Car competes directly with eight verified off-site lots near SEA. Here's how it stacks up on the features that matter most to travelers:

• Price: Extra Car's estimated $12–$16/day is competitive with Jiffy ($12.95), Ajax ($12.99), and MasterPark Lot A ($13.99). It's priced similarly to Doug Fox ($14.95) and WallyPark Outdoor ($14.95).
• Distance: At roughly 2 miles / 5–8 minutes from the terminal, Extra Car is comparable to most International Blvd lots. Doug Fox is closer at just 3 minutes — the fastest shuttle at SEA.
• Valet option: Extra Car and MasterPark Garage are among the few off-site lots offering valet. WallyPark and Jiffy do not offer valet.
• Loyalty program: Extra Car has a Frequent Parker Program. MasterPark also offers a rewards program. Most other lots do not.
• Covered parking: Extra Car's standard lot is uncovered. For covered off-site options, MasterPark Garage ($17.99/day) and WallyPark Premier Garage ($18.95/day) are the verified alternatives.
• Shuttle: All major SEA off-site lots offer free 24/7 shuttle service, so this is not a differentiator on its own.

What Is the Extra Car Frequent Parker Program and How Does It Work?

The Extra Car Frequent Parker Program rewards repeat customers with points or credits toward future parking stays. The program is designed for business travelers and frequent flyers who park at SEA multiple times per year.

The specific earning rate (points per dollar or per stay) and redemption thresholds (how many points equal a free day) are not published officially as of April 2026. Based on comparable programs at SEA-area lots, frequent parker programs typically offer one free parking day after a set number of paid stays — often 10–12 visits. If you park at Extra Car more than four or five times a year, signing up for the program is a no-cost way to earn toward free parking days.

Ask about enrollment at the lot's entrance booth on your first visit, or check for a sign-up option when booking online. There is no published annual fee for the program. Keep your receipts or booking confirmations to track your stay history if the program requires manual point submission.

2026 Construction at SEA: What Extra Car Parkers Should Know

Seattle-Tacoma International Airport is in the middle of a major expansion under the Sustainable Airport Master Plan (SAMP), with FAA approval issued in September 2025. The SEA Gateway Project — roadway and terminal frontage improvements — is targeting completion in 2026. Temporary detours near the terminal entrance are possible during construction, so allow extra buffer time when driving to and from Extra Car or any off-site lot on International Blvd.

The C Concourse Expansion ($260M) is nearing substantial completion in Q2 2026, adding 10+ new restaurants, retail, and an airside observation deck. The SEA parking garage remains fully operational throughout all construction phases. The 3rd floor Courtesy Vehicle area — where Extra Car's shuttle drops you off — is unaffected. For the most current road condition updates before your drive, check real-time traffic on Waze.
