What Are the Rules for BWI Long Term Parking?

The core bwi long term parking rules are set by the Maryland Aviation Administration (MAA), a unit of the Maryland Department of Transportation. The lots operate around the clock, and most rules are designed to keep the facility safe and accessible for all travelers.

Here are the key rules every parker should know:

• No oversized vehicles — vehicles that exceed standard passenger car dimensions are not permitted. This includes most commercial trucks, large box vans, and vehicles towing trailers. If you're driving an oversized vehicle, contact BWI parking services before your trip for guidance on alternatives.
• No vehicles with flammable gas containers — vehicles carrying propane tanks, compressed gas cylinders, or similar flammable materials are prohibited from the long term lots. This rule applies to the covered and uncovered lot areas alike.
• No abandoned vehicles — vehicles left beyond a reasonable period without contact are subject to impoundment at the owner's expense, per MAA policy.
• Motorcycles and bicycles — standard motorcycles are generally permitted in designated spaces; confirm specific location with parking staff on arrival. Bicycles are not permitted to be secured to lot infrastructure.
• No commercial activity — the lots are for private passenger vehicle parking only. No vehicle sales, repairs, or commercial storage is allowed.
• Speed limit — observe posted speed limits within the lot at all times. Pedestrian safety is enforced.

According to BWI's official long term parking page, the lots are managed by a professional parking operator. Staff are on-site and can assist with rule questions when you arrive.

How Much Does BWI Long Term Parking Cost Per Day?

BWI Long Term Lots A and B charge $11 per day as of July 1, 2024 — the first rate increase since 2009, per the Maryland Department of Transportation. This makes the long term lots the most affordable on-airport option at BWI.

Here's how the long term rate stacks up against every other on-airport option:

For a 7-day trip, the long term lot costs $77 total at the official rate. Off-site competitors like The Parking Spot (East) and FastPark 2 (BWI) start at $7.50/day, saving you roughly $24.50 on that same trip — a 32% discount compared to BWI's own long term rate.

Where Are BWI Long Term Parking Lots A and B Located?

Long Term Lot A and Long Term Lot B are both located off Aviation Boulevard (MD Route 170), south of the main terminal complex at BWI Marshall Airport. Both lots are clearly signed from the airport's primary access road, Interstate 195.

If you're driving in:

1. Take I-195 East toward the airport.
2. Follow signs for Long Term Parking at the airport entrance roundabout.
3. Turn onto Aviation Boulevard (MD-170) and follow the green long term parking signs.
4. Enter the lot using the automated ticket dispenser at the gate arm.
5. Take your ticket and proceed to an open space.

GPS users can search "BWI Long Term Parking Lot A" or "BWI Long Term Parking Lot B" for turn-by-turn directions. Before you leave home, check real-time traffic on Waze — especially during morning peak hours when I-195 and I-95 can back up near the airport interchange. Between the two lots, Lot A is typically the first you encounter when approaching from I-195. Lot B is adjacent and uses the same shuttle stop system.

How Does the BWI Long Term Parking Shuttle Work?

The free BWI long term parking shuttle picks up directly inside both Lot A and Lot B and drops you at the terminal's lower level. According to official BWI airport data, shuttles run every 10–15 minutes during normal hours. Between 1 AM and 5 AM, service slows to every 25 minutes.

Here's what to expect step by step:

1. Park your vehicle and note your exact space number and lot section.
2. Walk to the nearest numbered bus stop within the lot.
3. Board the shuttle — it's free and no ticket is required.
4. The ride to the terminal takes approximately 10 minutes, depending on traffic within the airport loop.
5. You'll be dropped at the lower level of the terminal, near the ticketing and check-in area.

On return, pick up the shuttle at the designated stop on the terminal's lower level. Shuttles serving the long term lots are clearly marked. For full details on timing and stop numbers, see our dedicated article on BWI long term parking bus hours and shuttle schedules.

What Vehicles Are Prohibited in BWI Long Term Parking?

Certain vehicles cannot use BWI Long Term Lots A or B under MAA regulations. This is one of the most commonly overlooked parts of the bwi long term parking rules.

• Oversized vehicles — any vehicle that cannot fit within a standard parking space. This includes large commercial vans, trucks over a certain height or length, vehicles with roof racks that exceed clearance, and vehicles towing trailers or campers.
• Vehicles carrying flammable gas containers — propane tanks, butane canisters, compressed gas cylinders, or any pressurized flammable material. This applies even to camping vehicles with built-in tanks.
• Inoperable vehicles — vehicles that cannot be driven under their own power are not permitted. You cannot tow or push a broken-down vehicle into a long term space.
• Unregistered or uninsured vehicles — parking is for legally registered passenger vehicles only.

If your vehicle is oversized or doesn't meet requirements, the off-site lots near BWI may have more flexible options. FastPark 2 (BWI) and FastPark & Relax (BWI) offer covered parking and on-site staff who can assist with non-standard vehicle needs. See our full breakdown in the airport parking near BWI guide.

How Do You Pay for BWI Long Term Parking?

BWI Long Term Lots accept cash, all major credit cards, and contactless payment at the exit pay stations. Based on official airport payment information, accepted cards include Visa, Mastercard, American Express, and Discover.

A few important payment rules to know:

• Pay before you exit: Pay stations are located throughout the lot. Pay your ticket before returning to your car to speed up the exit lane.
• Keep your ticket: You receive a paper ticket on entry. You'll need it to pay and exit. Lost tickets may result in the maximum daily rate being charged.
• No pre-reservation required: BWI's own long term lots do not offer advance online reservations. Parking is walk-up only — first come, first served.
• Partial-day billing: Fees are calculated based on your actual time in the lot. The rate is $11 per calendar day, with partial days billed at the daily rate once you cross a 24-hour threshold.
• No app payment at the lot itself: BWI's on-site pay stations are card and cash only; mobile app payment is not currently available at the long term lot exit lanes.

Because reservations aren't available for the official long term lots, pre-booking an off-site lot through Triply's BWI parking search is the only way to guarantee a space during peak travel periods.

What Happens If BWI Long Term Parking Lots Are Full?

When Long Term Lots A and B reach capacity, BWI directs overflow traffic to other on-airport options — typically Express Parking or the Daily Garage. Dynamic signs on I-195 and Aviation Boulevard display real-time lot availability, so you can see the status before you pull in.

If you arrive and the long term lots are full, here are your options:

• Express Parking ($14/day): Located near the Cell Phone Lot on Scott Road. Close to the terminal with shuttle service.
• BWI Rail Station Garage ($12/day): A solid backup option. A free shuttle connects the Rail Station to the terminal 24/7.
• Off-site lots: FastPark 2 (BWI) is just 2 minutes from the airport and rarely fills completely. The Parking Spot (East) and The Parking Spot (West) both run on-demand shuttles every 5–10 minutes.

The single best way to avoid this problem is to book an off-site lot in advance. Off-site providers like The Parking Spot and FastPark accept reservations, so your space is guaranteed. The on-site long term lots do not offer this option. During summer peak season and major holidays, BWI's ~22,000 on-airport spaces can fill faster than travelers expect.

Is BWI Long Term Parking Safe and Monitored?

Yes — BWI Long Term Lots A and B are actively monitored with surveillance cameras and regular security patrols, per the Maryland Aviation Administration. The lots are well-lit and fenced, with controlled entry and exit points.

Security features include:

• Surveillance cameras throughout both lots
• Controlled gate access — ticket required to enter and exit
• On-site parking staff and regular security patrols
• Well-lit lanes and walkways for safe nighttime arrival and departure
• Emergency call stations available within the lots

The lots are managed by a professional operator under contract with the MAA. If you have a security concern or need assistance — including a lost vehicle situation — contact the parking office directly through BWI's main parking line. One practical safety tip: note your exact space number and lot section on your phone before you leave. This makes finding your car on return far easier, especially after a long trip.

BWI Long Term Parking Rules vs. Off-Site Alternatives

Understanding the bwi long term parking rules makes it easier to compare on-site lots with off-airport options. Off-site lots have their own rules — and some are more flexible.

Based on our analysis of current rates, off-site lots save travelers an average of $24–$38 on a 7-day trip compared to the official $11/day on-site rate. The trade-off is a slightly longer shuttle ride — typically 2–7 minutes more than the on-site long term lot shuttle. For most travelers on trips of 4+ days, that extra few minutes is well worth the savings. If you plan to book off-site, always check BWI long term parking promo codes before checkout — discounts can push the rate even lower.

Book BWI Parking Before Your Trip

The bwi long term parking rules are straightforward once you know them. The long term lots offer BWI's cheapest on-airport rate at $11/day, reliable free shuttle service, and 24/7 access. Just remember: no oversized vehicles, no flammable gas, pay at the station on exit, and no advance reservations are available for the official lots. For the lowest guaranteed rate with a confirmed space, off-site options start at $7.50/day — and you can lock that in today.
