What Is BWI Long Term Lot B and Where Is It Located?

BWI Long Term Lot B is an on-airport surface parking lot located on the south side of the airport complex, off Aviation Boulevard (MD Route 170). It sits adjacent to Long Term Lot A and is part of the same long-term parking zone managed by the MAA. Both lots share the same daily rate and shuttle infrastructure.

To reach Lot B, take Interstate 195 (the primary airport access road) and follow signs for Long Term Parking. From I-195, exit onto Aviation Boulevard and continue toward the Long Term Parking area. GPS navigation works well here — search "BWI Long Term Parking" and your device will route you directly. Travelers coming from Interstate 97 (from Annapolis) or the Baltimore-Washington Parkway (MD-295) should connect to I-195 first.

The lot is entirely at surface level, which means no multi-story garage navigation. Signage throughout the lot directs you to numbered shuttle stop zones. Note your shuttle stop number when you park — this is the single most important tip for finding your car on return. The lots are large enough that forgetting your stop zone can cost you real time at the end of a trip.

BWI's total on-airport parking capacity is approximately 22,000 spaces across all facilities, according to official airport data. The Long Term lots (A and B combined) account for a significant share of that total, making them among the most spacious parking areas at the airport.

How Much Does BWI Long Term Lot B Cost Per Day? (2026 Rates)

BWI Long Term Lot B costs $11 per day — the flat daily maximum for all on-airport long-term parking, per the Maryland Aviation Administration (verified June 2026). There is no hourly rate in Lot B; the $11/day charge applies from the moment you pull a ticket.

These rates took effect on July 1, 2024 — the first parking rate increase at BWI since 2009. The full breakdown of on-airport options, including how Lot B compares to the Daily Garage and Express Parking, is covered in depth in our Baltimore Washington Airport Parking Rates 2026 guide. Here's a quick trip-length cost estimate for Lot B:

There are no weekly discount rates or early-bird pricing tiers for Long Term Lot B — you pay the flat $11/day regardless of how long you stay. The lot accepts cash, Visa, Mastercard, American Express, Discover, and contactless payment at exit lanes.

If you're searching for BWI long term parking coupons to reduce your total cost, those discounts apply to off-airport lots — not to on-airport facilities like Lot B, which are priced at fixed MAA rates.

How Does the Shuttle Service Work from Long Term Lot B to the Terminal?

The free BWI shuttle picks you up directly from numbered stops within Long Term Lot B and delivers you to the main terminal. According to official airport data, the shuttle runs every 10-15 minutes during normal hours and every 25 minutes between 1–5 AM. The ride itself takes approximately 5-10 minutes depending on lot congestion and traffic near the terminal loop.

Here's what to expect from the shuttle experience:

1. Park your vehicle and locate the nearest numbered shuttle stop sign within Lot B
2. Write down or photograph your shuttle stop number — you'll need it to find your car when you return
3. Wait at the covered shelter (most stops have one) — real-time arrival displays show the next shuttle's ETA
4. Board the shuttle with your luggage; the driver or assistant can help with bags
5. The shuttle drops you at the terminal lower level, near the ticketing and check-in entrances

On return, follow "Parking Shuttles" signs after baggage claim. Shuttles to Long Term lots depart from the terminal's lower level. Allow at least 20-25 minutes of buffer from when you leave baggage claim to when you're back in your car — more during peak travel periods. The shuttle service runs 24 hours a day, 7 days a week, so late arrivals are covered.

How Does Long Term Lot B Compare to Other BWI Parking Options?

At $11/day, Long Term Lot B is the most affordable on-airport option. But the right choice depends on how long you're parking and how close you need to be to the terminal. Here's how Lot B stacks up against every on-airport option, per MAA's published rates (verified June 2026):

For a deeper look at how BWI Airport Express Parking compares on shuttle speed and convenience, see our dedicated BWI Airport Express Parking guide. Express Parking costs $3 more per day than Lot B but is positioned closer to the terminal with a slightly faster shuttle.

One key difference between Lot A and Lot B: both charge the same $11/day rate and share the same shuttle network. The main practical difference is physical location within the long-term parking zone. If Lot A is full, airport staff will direct you to Lot B — and vice versa. For a full side-by-side on Long Term Lot A, visit our BWI Long Term Parking A guide.

How Does BWI Long Term Lot B Compare to Off-Airport Parking Near BWI?

Off-airport lots beat BWI Long Term Lot B on price for most trip lengths. The cheapest off-site options — The Parking Spot (East), The Parking Spot (West), and FastPark 2 (BWI) — all start at $7.50/day, which is 32% cheaper than Lot B's $11/day rate. On a 7-day trip, that's a $24.50 saving. Here's how the full off-airport field compares to Lot B:

Off-airport lots do require a shuttle ride of roughly 5-10 minutes from a private facility. But FastPark 2 (BWI) is just 2 minutes from the terminal and includes covered parking — that's a better deal than Lot B on both price and weather protection. For more options in the surrounding area, our Airport Parking Near BWI guide covers every major provider with current rates.

The one advantage Lot B retains: it's operated directly by BWI, which some travelers prefer for peace of mind on long trips. But based on our analysis, the off-airport lots listed above all include 24/7 security, surveillance cameras, and free cancellation — so safety is comparable.

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

Long Term Lot B is an open-air surface lot, so there are no vehicle height restrictions — a key advantage over garage parking. Large vehicles, SUVs, trucks, and cargo vans all fit without issue. That said, oversized commercial vehicles or trailers are generally not permitted in standard passenger lots.

Key rules to know before you park:

• No reservations required — Long Term Lot B operates on a first-come, first-served basis. You pull a ticket at the entry gate and pay on exit.
• Payment at exit — Pay at automated pay stations before returning to your vehicle, or pay at the exit lane directly. Accepted methods: cash, Visa, Mastercard, Amex, Discover, and contactless payment.
• Accessible parking — Accessible spaces are available throughout the long-term lots. The closest ADA spaces to the shuttle stops are clearly marked.
• No overnight storage — Long-term parking is intended for trip-length stays, not indefinite vehicle storage.
• 24-hour access — The lot is open for entry and exit around the clock, every day of the year.

BWI is actively rolling out smart parking guidance systems as part of ongoing technology upgrades across its facilities. These real-time availability displays help you find open zones faster when the lot is busy — especially useful around major holidays. Check the BWI official long-term parking page for current lot availability before you drive.

Tips for Parking in BWI Long Term Lot B: Before You Go and When You Return

A few habits can turn a stressful parking experience into a smooth one. These tips apply specifically to BWI Long Term Lot B and its layout.

Before You Leave

• Check traffic on Waze before you leave home — the I-195 corridor into BWI can back up during peak hours. Use the Waze live traffic map to time your departure.
• Arrive at least 90 minutes before domestic flights and 2+ hours before international departures to account for the shuttle ride and security.
• If you have TSA PreCheck, your security wait will be shorter — but you still need time for the shuttle and check-in.
• Bring exact change or a payment card. Contactless payment works at BWI exit lanes.
• Photograph your shuttle stop number and parking row before walking away from your car.

During Your Trip

• Save your parking ticket. You'll pay before returning to your vehicle at an automated station inside the terminal or at the lot.
• Note whether you parked in Lot A or Lot B — they are adjacent but served by the same shuttle loop. Return passengers board at the terminal's lower level.

When You Return

• Follow signs to "Long Term Parking Shuttles" after baggage claim on the lower level.
• Tell the driver your stop number — they'll confirm when to exit.
• Budget 20-25 minutes from the terminal exit to being back in your car. Add more time if you checked bags and it's a peak travel day.
• The new $520 million Concourse A/B Connector, which opened January 9, 2026, improved interior navigation between Concourses A and B significantly. If you're flying Southwest, you'll notice the terminal flow is smoother than in previous years.

Is BWI Long Term Lot B Safe for Overnight and Extended Stays?

BWI Long Term Lot B is a secure, staffed facility managed by the Maryland Aviation Administration. As part of BWI's official parking infrastructure, the lot operates under the same security standards as all on-airport facilities. Expect perimeter fencing, surveillance cameras throughout, and regular patrols.

The lot is well-lit overnight. Based on traveler reports and our analysis of on-airport parking operations, extended stays of a week or more are routine here.

Off-airport alternatives like FastPark 2 (BWI) offer covered parking at $7.50/day if weather protection is a priority.

For added security during travel, follow standard precautions: remove valuables from your vehicle, lock it, and take a photo of your parking spot before you board the shuttle. BWI's on-site parking assistance line (listed on the BWI parking page) can help if you have issues locating your vehicle on return.
