BWI Long Term Parking Map: 2026 Guide to Lots A & B

Back to BWI Long Term Parking A | Complete BWI Airport Parking Guide

BWI Long Term Parking is a pair of large open-air surface lots — Lot A and Lot B — located on the south side of Baltimore/Washington International Thurgood Marshall Airport along Aviation Boulevard (MD-170). The BWI long term parking map shows both lots sitting just off MD-170, roughly a 5–10 minute free shuttle ride from the terminal. The official rate is $11/day (verified June 2026), making these the most affordable on-airport option at BWI. With ~22,000 total parking spaces across all on-airport facilities, Long Term Lots A and B hold the largest share of that capacity.

• Rate: $11/day, the cheapest on-airport parking at BWI as of 2026, per the Maryland Aviation Administration.
• Location: Long Term Lots A and B sit along Aviation Boulevard (MD-170), south of the terminal.
• Shuttle: Free shuttle runs every 10 to 15 minutes (every 25 minutes between 1 AM and 5 AM).
• Access roads: Best reached via I-195, MD-295 (Baltimore-Washington Parkway), or MD-170 directly.
• Off-airport alternative: Triply sells five lots near BWI at about $6 to $8/day, roughly 24% to 44% less than the $11/day Long Term rate. These rates are for a 7-day stay booked ahead and change by date.
• 2026 update: The $520M Concourse A/B Connector opened January 9, 2026. There are no parking layout changes, but terminal navigation is easier now.

Where Is BWI Long Term Parking? (Map of Lots A and B)

BWI Long Term Lots A and B are both located along Aviation Boulevard (MD-170), on the south side of the airport complex. Lot A sits closer to the terminal end of Aviation Boulevard, while Lot B extends further south. Both are surface lots — no parking garage structures, no height restrictions.

Here is how to picture the BWI long term parking map layout:

• Lot A — Entered from Aviation Boulevard (MD-170). Closest of the two long-term lots to the terminal shuttle stop. Ideal for travelers who want a shorter walk to the shuttle.
• Lot B — Also entered from Aviation Boulevard, positioned further along the road from Lot A. Slightly longer walk to the shuttle pickup, but typically has more available spaces on busy travel days.
• Shuttle stops — Each lot has clearly marked numbered shuttle shelter stops. Note your stop number when you park — you'll need it on return.
• Cell Phone Lot — Located on Scott Road, across from Express Parking near I-195 and Aviation Boulevard. Free for up to one hour. Not a substitute for long-term parking, but useful if you're picking someone up.

For GPS navigation, use 7050 Aviation Boulevard, Linthicum, MD 21090 as a general reference point for the Long Term Lot entrance area off MD-170. Signage on Aviation Boulevard directs you clearly to both lots once you exit I-195 or MD-295. You can also view the official BWI long term parking page for the most current lot layout information.

How Much Does BWI Long Term Parking Cost in 2026?

BWI Long Term Lots A and B both cost $11 per day, per the Maryland Aviation Administration (MAA). This rate took effect July 1, 2024 — the first price increase since 2009. The rate applies to both lots equally, with no difference between Lot A and Lot B pricing.

Here is how Long Term parking fits into the full BWI on-airport pricing picture (verified June 2026):

A 7-day trip in Long Term parking costs $77 total. That same trip in the Daily Garage runs $112, which is $35 more for the same destination. For travelers looking to cut costs even further, the off-airport lots Triply sells start at about $6/day, or about $43 for 7 days. See our full BWI long term parking cost breakdown for weekly and extended stay rate calculations.

How Do You Get from BWI Long Term Parking to the Terminal?

A free shuttle connects Long Term Lots A and B to the BWI terminal 24 hours a day, 7 days a week. The shuttle runs every 10–15 minutes during normal hours and every 25 minutes between 1–5 AM, according to official BWI airport data. The ride from the lots to the terminal takes approximately 5–10 minutes.

Here is exactly how the shuttle process works:

1. Park your car and note the numbered shelter stop closest to your space.
2. Walk to the nearest shuttle shelter — they are marked with large numbers and have seating.
3. Board the free shuttle when it arrives. Shuttles are clearly marked for Long Term Lots.
4. Ride to the terminal — the shuttle drops off at the upper level departures area.
5. On return, pick up the shuttle from the Ground Transportation area on the lower level of the terminal.

The shuttle stop number you noted when parking is critical on the return trip. It tells the driver exactly which section of the lot to drop you at. Forgetting it means a longer walk through the lot to find your car. For more detail on the full shuttle process, our BWI long term parking shuttle guide covers exact stop locations, shuttle hours, and what to do if your shuttle is delayed.

How Do You Drive to BWI Long Term Parking from I-95, MD-295, and MD-170?

All three major approach routes funnel onto Aviation Boulevard (MD-170), which runs directly past Long Term Lots A and B. Once you reach MD-170, follow the blue Long Term Parking signs. Before you head out, check real-time traffic on Waze — traffic on I-95 near the I-195 interchange can back up during morning and evening peaks.

From I-95 (North or South)

1. Take I-195 East (Exit 47 from I-95).
2. Follow I-195 to the MD-170 / Aviation Boulevard exit.
3. Turn onto Aviation Boulevard and follow signs for Long Term Parking.
4. Lot A entrance appears first. Lot B is further along the same road.

From MD-295 (Baltimore-Washington Parkway)

1. Take the MD-170 / Aviation Boulevard exit from MD-295.
2. Head north on Aviation Boulevard toward the airport.
3. Follow Long Term Parking signage on the left side of the road.

From MD-170 / Aviation Boulevard Directly

1. If you are already on MD-170, simply follow the road north toward the airport.
2. Long Term Lot signs appear on the right before you reach the main terminal loop.
3. Both Lot A and Lot B are accessible without entering the terminal roadway.

From Annapolis, take I-97 North to I-695 West, then merge onto I-195 East toward the airport. From Downtown Baltimore, take MD-295 South directly to the MD-170 exit. BWI sits 9 miles south of downtown Baltimore and 30 miles northeast of Washington, D.C., so approach routes vary significantly by your origin.

What Is the Difference Between BWI Long Term Lot A and Lot B?

Both lots charge $11/day and use the same free shuttle, but their positions along Aviation Boulevard differ. Lot A is generally considered the primary lot and fills first on busy travel days. Lot B serves as overflow and is further from the main entrance point.

• Lot A: Closer to the terminal-side end of Aviation Boulevard. Usually the first lot you reach when driving in from I-195. Tends to fill faster on holidays and summer Fridays.
• Lot B: Further along Aviation Boulevard. More likely to have spaces available during peak periods. Same $11/day rate. Same shuttle service.
• Accessibility: Accessible parking spaces are available in both lots. The closest ADA spaces to the terminal are in the Hourly and Daily Garages if you need a shorter walk.
• Vehicle restrictions: Vehicles carrying flammable gases are not permitted in enclosed garages. Long Term Lots A and B are open surface lots, so they are generally appropriate for most oversized or specialty vehicles — but always confirm with BWI's official parking page before arrival.
• EV charging: EV charging stations are available within BWI's on-airport parking facilities. Confirm current locations via the BWI official parking page as station availability may update.

How Does BWI Long Term Parking Compare to Off-Airport Options?

The off-airport lots Triply sells near BWI start at about $6/day, roughly $5/day less than Long Term Lots A and B at $11/day. Over a 7-day trip, that is about $43 versus $77, a gap of about $34 at the cheapest lot. The trade-off is that each off-airport lot has its own shuttle schedule, and two of them have gaps in service.

Doubletree Baltimore stands out in this comparison. At about $6/day it is the cheapest lot Triply sells near BWI, about 44% less than Long Term Lots A and B, and its shuttle runs 24 hours a day. It is listed 2.2 miles from the airport, and you register your car at the front desk for a dashboard tag. Country Inn & Suites is the closest at 1.7 miles, but its shuttle has gaps from noon to 4 PM and from midnight to 4:30 AM. Across all five lots, a 7-day trip runs about $43 to $58, compared with $77 in Long Term parking, which is about $19 to $34 less.

What Are the Rules and Restrictions for BWI Long Term Parking?

BWI Long Term Lots A and B operate 24/7 and accept all standard payment methods, including cash, Visa, Mastercard, American Express, Discover, and contactless payment. There is no attendant-based checkout — payment is processed at exit lanes.

• Payment: Cash, all major credit cards, and contactless payments are accepted at exit lanes.
• Reservation: BWI has been rolling out a parking reservation system as part of ongoing technology upgrades. Check the official BWI parking page to confirm availability before your trip.
• Flammable gas vehicles: Not permitted in enclosed garages — but since Long Term Lots A and B are open surface lots, they are typically accessible. Confirm with BWI directly for your specific vehicle type.
• Accessible parking: ADA spaces are available in both Long Term Lots. The closest accessible spaces to the terminal building are in the Hourly and Daily Garages for those needing minimal walking distance.
• Maximum stay: No published maximum stay limit for Long Term parking, making it suitable for extended trips.
• Overnight parking: Both lots are open and staffed overnight. Security cameras and regular patrols are standard features.

Before you fly, review TSA security screening guidelines — knowing what to expect at the checkpoint helps you plan your terminal arrival time after the shuttle ride. If you enroll in TSA PreCheck, you can move through security faster and reduce the time pressure after parking.

The $520 million Concourse A/B Connector opened on January 9, 2026 — the largest capital project in BWI history. It created a direct single-level connection between Concourses A and B, which Southwest Airlines passengers will find especially useful. Parking lot layouts were not changed by this project, but terminal navigation from the shuttle drop-off is smoother than it was before 2026.
