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

BWI Long Term Parking Lot B is an open-air surface lot located on the south perimeter of BWI Marshall Airport, accessible via MD Route 170 (Aviation Boulevard). It sits near Long Term Lot A and is part of the airport's dedicated long-term parking zone, separate from the closer-in Daily Garage and Express Parking areas.

To reach Lot B, take Interstate 195 (the primary airport access road off I-95) and follow signs for Long Term Parking. From MD Route 170 (Aviation Boulevard), the lot entrance is well-marked with overhead signage. Travelers coming from Annapolis can use Interstate 97, connecting to I-195. The lot is also reachable via the Baltimore-Washington Parkway (MD-295) using I-195 as the final approach.

Because Lot B is an uncovered surface lot, your vehicle is exposed to the elements. In Maryland summers and winters, that matters — plan accordingly. If covered parking is important, FastPark 2 (BWI) nearby offers covered long-term parking at $7.50/day. For a full rate breakdown across all BWI options, see our guide to Baltimore Washington Airport parking rates in 2026.

How Much Does BWI Long Term Parking Lot B Cost Per Day?

BWI Long Term Parking Lot B costs $11 per day, per the Maryland Aviation Administration's official published rates (effective July 1, 2024 — the first price increase since 2009). There is no maximum beyond the daily rate, so multi-day costs are straightforward to calculate.

Some third-party booking platforms display lower rates for BWI long-term parking. Those prices typically reflect pre-negotiated off-site lot rates, not Lot B itself. The official on-airport rate of $11/day is set by MAA and applies at all Long Term lots. If you see $8/day, that's most likely an off-site facility like The Parking Spot (East) or FastPark & Relax (BWI), not Lot B on airport property.

For context, here's how Lot B compares to every other on-airport option at BWI, based on official MAA published rates (verified June 2026):

Long Term Lot B is the cheapest on-airport option at BWI — $5/day less than the Daily Garage and $19/day less than the Hourly Garage for multi-day stays.

How Often Does the Shuttle Run from Long Term Lot B to the Terminal?

The free BWI shuttle from Long Term Lot B runs every 10–15 minutes during normal hours and every 25 minutes between 1 AM and 5 AM, according to official BWI airport shuttle information. The service operates 24 hours a day, 7 days a week.

Shuttle stops are numbered throughout Long Term Lots A and B. When you park, note your shuttle stop number — it's the key to finding your car when you return. The shuttle makes multiple stops within the lot before heading to the terminal, so your actual ride time may be a few minutes longer depending on which stop you're picked up from.

A few practical tips for the shuttle:

• Many stop locations in Lots A and B have real-time arrival monitors showing the next shuttle's ETA
• During peak travel periods — Thanksgiving, summer weekends, and spring break — expect slightly longer waits due to higher lot volume
• If you arrive between 1–5 AM, the 25-minute headway means plan an extra buffer before your flight
• The shuttle drops off at the lower level of the terminal, near the ticketing area
• Budget at least 20–30 minutes from parking to reaching your gate, including shuttle time and the walk inside

Long Term Lot A vs Lot B at BWI: Which Should You Choose?

Both Long Term Lot A and Lot B charge the same rate — $11/day — and share the same shuttle system. The main differences come down to location within the lot complex, shuttle stop assignment, and how full each lot is on any given day.

In practice, the difference between Lot A and Lot B is minor for most travelers. Lot A tends to fill first on busy travel days because it's the first lot you encounter entering from the main road. Lot B is often a better bet during peak periods because it typically has more availability. If Lot A appears full, signage will direct you directly to Lot B without any detour.

How to Park in BWI Long Term Lot B: Step-by-Step Guide

First-time parkers at BWI Long Term Lot B can move through the process smoothly with this walkthrough. The system is straightforward, but knowing what to expect saves time.

1. Approach via I-195: Take I-195 off I-95, then follow signs for Long Term Parking. Stay on MD Route 170 (Aviation Boulevard) and watch for the Long Term Parking entrance signs.
2. Enter the lot: Pull up to the entry gate. Take a ticket if dispensed, or tap your contactless payment to open the gate — BWI has been upgrading to smart entry systems.
3. Find a space: Follow overhead guidance signs (part of BWI's parking technology upgrades). Drive to an open row and park.
4. Note your shuttle stop number: Look at the nearest numbered post or sign. Write it down or photograph it. This is how you find your car on return.
5. Board the shuttle: Walk to your stop and wait for the next shuttle. It arrives every 10–15 minutes. The driver will confirm the terminal drop-off.
6. At the terminal: The shuttle drops off at the lower level. Follow signs upstairs to check-in and security. If you have TSA PreCheck, look for the dedicated lanes — they move significantly faster.
7. On return: After baggage claim, follow signs to the Long Term Parking shuttle pickup zone on the lower level. Board the shuttle and tell the driver your stop number.
8. Pay at exit: At the exit booth or automated kiosk, pay by cash, credit card, or contactless method. Keep your ticket from entry.

Is BWI Airport Long Term Parking Lot B Safe and Secure?

BWI Long Term Lot B is monitored by the Maryland Aviation Administration with security cameras, regular patrol, and perimeter fencing as standard features of MAA-managed lots. As with any large open-air surface lot, common-sense precautions apply.

Here's what to know about security in Long Term Lot B:

• Surveillance cameras are positioned throughout the lot
• MAA security patrols cover Long Term lots as part of airport operations
• Good lighting across primary drive lanes and shuttle stop areas
• The lot is fully enclosed with controlled entry and exit points
• Do not leave valuables visible in your vehicle — this applies to all open-air lots, on or off airport

Traveler forums occasionally mention isolated incidents at large airport surface lots, which is a known risk with any unsupervised outdoor parking. If security is a top concern, the on-airport Daily Garage ($16/day) offers an enclosed structure with tighter access control. Alternatively, FastPark 2 (BWI) provides covered, 24/7 staffed parking at $7.50/day — with luggage assistance and a 2-minute shuttle.

How Does BWI Long Term Parking Lot B Compare to Off-Site Alternatives?

Off-site lots near BWI can save you up to 32% compared to Long Term Lot B's $11/day rate, based on our analysis of verified lot data. The trade-off is that you're leaving airport property — though all major off-site providers include free 24/7 shuttles.

FastPark 2 (BWI) stands out as the strongest off-site value. It's covered, staffed around the clock, includes luggage assistance, and sits just 2 minutes from the terminal — all at $7.50/day. Over a 7-day trip, that saves you $24.50 compared to Lot B. The Parking Spot (East and West) match that $7.50 rate with on-demand shuttles every 5–10 minutes and free water bottles.

The main reason to choose Lot B over off-site options is simplicity — you stay on airport property, there's no need to pre-book, and the shuttle is part of the official airport system. If you prefer to lock in a guaranteed spot and pay less, booking off-site in advance is the smarter move. Need a coupon or prepaid deal?

Tips for Saving Money and Time at BWI Long Term Parking Lot B

These practical tips apply whether you're parking at BWI Airport Long Term Parking Lot B for a weekend trip or a two-week vacation.

• Check traffic before you drive. I-195 and I-95 can back up badly during peak hours. Use the Waze live traffic map to time your arrival and avoid delays that eat into your buffer time.
• Arrive 90 minutes before domestic flights. Factor in parking, the shuttle ride, terminal check-in, and security. BWI's new $520 million A/B Connector (opened January 9, 2026) has improved flow between Concourses A and B, but security lines vary.
• Photograph your shuttle stop number. This is the single most common mistake returning travelers make. A photo takes two seconds and saves real frustration.
• Travel light through the lot. Lot B is an open surface lot — rolling a large bag across asphalt is tiring. Pack efficiently or consider a lot with luggage assistance like FastPark 2.
• Compare before you commit. Lot B has no advance reservation system currently. Off-site lots let you pre-book and often offer lower rates. Check both options before your trip.
• Avoid peak travel days when possible. Thanksgiving week, July 4th weekend, and spring break Fridays fill Lot B fast. Arrive earlier or book off-site in advance if you're traveling on those dates.
• Know your payment options. BWI Long Term lots accept cash, all major credit cards, and contactless payment. For a full breakdown of how the payment process works, see our guide on how to pay for BWI long term parking.
