What Is BWI Long Term Parking and How Does It Work?

BWI long term parking is a set of surface lots and a garage at Baltimore/Washington International Thurgood Marshall Airport designed for travelers leaving their car for multiple days. You drive directly to Long Term Lot A or Lot B, park your car, and board a free shuttle to the terminal. No need to interact with an attendant — just grab your ticket at the entry gate.

The lots are managed by SP+ under contract with the Maryland Aviation Administration (MAA), a unit of the Maryland Department of Transportation. According to the official BWI long term parking page, the lots are open 24 hours a day, 7 days a week. Payment is accepted at exit lanes in cash, Visa, Mastercard, American Express, Discover, and contactless methods.

The lots are surface-level and uncovered, which means your car is exposed to weather. Summer heat and winter snow are real factors. If covered parking is a priority, FastPark 2 (BWI) nearby offers a covered option at comparable rates — more on that below.

How Much Does BWI Long Term Parking Cost? (2026 Rates)

BWI long term parking costs $11 per day as of July 1, 2024, per the Maryland Aviation Administration. That makes it the cheapest on-airport parking option at BWI. Here's how all on-airport options compare side by side.

A 7-day trip in the Long Term Lot runs $77 total. That's a 32% savings compared to the Daily Garage at $112 for the same trip.

Long Term Lot A vs. Lot B: What's the Difference?

Both Long Term Lot A and Long Term Lot B charge the same $11/day rate and connect to the terminal via the same free shuttle system. The main difference is location and size. Together, they form the bulk of BWI's surface parking capacity, which contributes to the airport's total of approximately 22,000 on-airport parking spaces.

• Long Term Lot A — Located off MD Route 170 (Aviation Boulevard). Typically the first lot drivers reach when entering from Interstate 195. Larger surface lot.
• Long Term Lot B — Adjacent to Lot A. Also accessible via Aviation Boulevard. Often the overflow lot when Lot A fills during peak travel periods.

During major holidays — Thanksgiving, July 4th, spring break weeks — both lots can fill completely. If you're traveling during a peak period, book in advance or arrive early. Lots can reach capacity by mid-morning on busy departure days. If both lots are full, airport staff typically direct drivers to available overflow areas, but this adds time. Checking real-time availability before you leave home is always a smart move.

How Do BWI Long Term Parking Shuttles Work — and How Often Do They Run?

The free BWI long term parking shuttle picks you up directly in the lots and drops you at the terminal's lower level. According to official BWI airport data, shuttles run every 10-15 minutes during normal hours, and every 25 minutes between 1-5 AM. Service runs 24 hours a day, 7 days a week.

The shuttle route connects Long Term Lots A and B to the main terminal, along with Express Parking, the Daily Garage, and the BWI Rail Station. Plan for roughly 10-20 minutes total from when you park to when you reach the terminal — including the wait for the shuttle and the ride itself. Factor this into your pre-flight planning, especially if security lines are long.

Speaking of security: enrolling in TSA PreCheck cuts checkpoint time dramatically. If you have PreCheck, you'll clear security faster and the extra shuttle time becomes less of a concern.

When you return, follow the signs to the baggage claim level and look for the Ground Transportation area. Shuttle buses are labeled by lot. The same 10-15 minute frequency applies on the return trip.

How Does BWI Long Term Parking Compare to Off-Site Parking Near BWI?

Off-site lots near BWI can cost 32-47% less per day than the on-airport Long Term Lots — and some run shuttles that are faster than the on-site service. Here's a direct comparison of your best options (verified June 2026).

FastPark 2 (BWI) stands out for long trips. It's covered, 24/7 staffed, includes luggage assistance, and runs a shuttle roughly every 5-10 minutes — all at $3.50/day less than the on-airport Long Term Lot. On a 10-day trip, that's $35 in savings for a faster, covered experience. All off-site lots listed above offer free cancellation.

How to Get to BWI Long Term Parking: Directions and GPS Tips

The Long Term Lots are accessible via MD Route 170 (Aviation Boulevard), the primary surface road that loops around BWI. From Interstate 195 (the main airport access road off I-95), follow the signs for Long Term Parking once you exit. The lots are clearly marked at multiple decision points.

• From the north (Baltimore): Take I-95 South to I-195 East. Follow signs for BWI Long Term Parking on Aviation Boulevard.
• From the south (Washington, D.C.): Take the Baltimore-Washington Parkway (MD-295) North or I-95 North to I-195 East. Follow Long Term Parking signs.
• From Annapolis: Take I-97 North to I-195 East. Aviation Boulevard exits are well-signed.
• From US Route 1: Use MD Route 176 (Dorsey Road) to connect to Aviation Boulevard.

Before you leave home, check real-time traffic on Waze — especially during morning rush hour or holiday weekends. Traffic on I-195 and Aviation Boulevard can back up during peak departure windows. Building in an extra 15-20 minutes during busy periods is smart planning.

GPS tip: Search for "BWI Long Term Parking" or the lot's address on Aviation Boulevard, Linthicum, MD 21090. The signs inside the airport road network are reliable, but GPS sometimes routes you to the terminal first. Follow airport signage once you're off the highway.

Tips for Parking Long Term at BWI: Saving Money, Staying Safe, and Finding Your Car

The BWI long term parking garage and surface lots are well-monitored, but a few habits make your trip smoother — especially after a long flight when you're tired and disoriented.

Save Money

• Book in advance. Pre-booking locks in your rate and guarantees a space, especially during peak travel. Use Triply's BWI parking search to compare on-site and off-site rates side by side.
• Check for coupons. Discounts and promo codes are sometimes available for BWI lots. Our BWI Long Term Parking Coupon guide lists current deals and how to apply them.
• Compare off-site options. FastPark 2, The Parking Spot East, and The Parking Spot West all offer rates starting at $7.50/day — 32% cheaper than the on-airport Long Term Lot rate, per current Triply listings.

Stay Safe

• BWI's on-airport lots and garages are patrolled and monitored with surveillance cameras. The lots are well-lit at night.
• Lock your car and avoid leaving valuables visible. Surface lots are open, and this is standard airport lot advice regardless of security level.
• Major off-site lots like FastPark 2 are 24/7 staffed, adding an extra layer of security beyond what surface lots provide.

Find Your Car After Your Trip

• Take a photo of your parking spot number and the lot name before you board the shuttle. The lots are large — easily hundreds of rows.
• Save your parking ticket in your carry-on, not your checked bag. You'll need it to exit.
• Note the shuttle stop you boarded from. Each stop has a designated number or letter posted on a sign — that's your landmark when you return.
• If you park in Lot B and the shuttle drops at Lot A, there will be a short walk or a second stop. Allow for this on the return leg.

Weather Considerations

The Long Term Lots are uncovered surface lots. In summer, your car will be hot after a week in the sun — especially with a dark interior. In winter, budget a few minutes to scrape ice or snow after returning from a trip. If you want covered parking, FastPark 2 (BWI) is the closest covered off-site option at the same price point.

What's New at BWI in 2026 That Affects Long Term Parkers?

BWI completed its $520 million Concourse A/B Connector project on January 9, 2026 — the largest capital project in airport history. The new connector links Concourses A and B with a direct single-level route, adding 142,000 sq ft of new space including expanded gates, new concessions, and upgraded restrooms. For long term parkers, this means a faster, more direct path through the terminal once your shuttle drops you off.

The airport is also rolling out smart parking guidance systems that help drivers find available spaces faster. This technology reduces the time spent circling lots during peak periods — a meaningful improvement given how large the Long Term Lots are. Contactless payment options are also being expanded across all facilities.

The new in-line baggage handling system now processes 3,500 bags per hour (up from 2,100), which means faster baggage claim on arrival — one less reason to rush once you deplane. All together, 2026 is a strong year to be a BWI long term parker.
