How Does the BWI Long Term Parking Shuttle Work?

The BWI long term parking shuttle is a complimentary bus service operated by the Maryland Aviation Administration (MAA), a unit of the Maryland Department of Transportation. It runs continuously between Long Term Lots A and B and the main terminal building. Here is exactly how the process works, step by step.

From Your Car to the Terminal

1. Drive into Long Term Lot A or Lot B via the posted signs off Aviation Boulevard (MD Route 170) or Dorsey Road (MD Route 176).
2. Find a space, note your row and section number — this matters when you return.
3. Walk to the nearest covered shuttle shelter within the lot. Multiple stops are spaced throughout each lot to reduce walking distance.
4. Check the real-time next-arrival monitor at the shelter. The display shows estimated minutes until the next bus.
5. Board the shuttle with your bags. Drivers assist with luggage if needed.
6. The shuttle drops you at the terminal upper level, near the departures entrance. Walk straight in to check in and clear security.

Returning from the Terminal to Your Car

1. After baggage claim, exit to the lower level Arrivals roadway.
2. Look for the clearly marked Long Term Parking shuttle zone — signage is posted along the curb.
3. Board the next shuttle and tell the driver which lot (A or B) if prompted.
4. The shuttle drops you at the stop nearest your row. Use your noted section number to walk directly to your car.

According to BWI's official long term parking page, the shuttle serves Long Term Lots, Express Parking, the Daily Garage, and the BWI Rail Station — all on the same route loop. Factor in a total of 20–30 minutes from parking your car to reaching your check-in counter, based on typical shuttle and walk times.

How Much Does BWI Long Term Parking Cost Per Day, Week, or Month?

BWI Long Term Parking costs $11 per day — the lowest rate of any on-airport option at Baltimore/Washington International Thurgood Marshall Airport, per official MAA published rates (verified June 2026). These rates took effect July 1, 2024, the first increase since 2009.

For a one-week trip, long term parking saves you roughly $35 compared to the Daily Garage and up to $133 versus the Hourly Garage. Off-airport options like The Parking Spot and FastPark 2 do undercut even the long term rate — check our guide to BWI long term parking costs in 2026 for a full weekly and multi-day breakdown. Payment is accepted by cash, Visa, Mastercard, Amex, Discover, and contactless methods at the lot pay stations.

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

Long Term Lot A and Lot B are both located off Aviation Boulevard (MD Route 170), south of the terminal complex. Signs direct you from Interstate 195 — the primary airport access road — directly to the long term lots before you reach the main terminal loop.

• Long Term Lot A is the first lot you encounter heading in from I-195. It is the larger of the two and is best for travelers arriving from the north via I-95 or Baltimore-Washington Parkway (MD-295).
• Long Term Lot B sits adjacent to Lot A. It is a solid alternative when Lot A fills during peak periods. For a detailed look at Lot B specifically, see our guide to BWI Long Term Parking Lot B shuttle and rates.
• Both lots are within the airport's approximately 22,000-space on-airport parking system, per official BWI facility data.
• GPS users should enter "BWI Long Term Parking" or use the Aviation Boulevard address. Travelers from Annapolis can approach via Interstate 97, then I-195.

Before you leave home, check real-time traffic on Waze — especially on weekday mornings when I-95 and I-195 can back up significantly heading toward BWI from the Baltimore side.

How Often Does the BWI Long Term Parking Shuttle Run?

The BWI long term parking shuttle runs every 10–15 minutes during standard hours, and every 25 minutes between 1:00 AM and 5:00 AM. Service is 24 hours a day, 7 days a week, 365 days a year — including holidays.

During peak travel periods — summer weekends, Thanksgiving, and spring break — expect waits closer to the 15-minute end of the range or slightly beyond. The real-time arrival monitors at each shelter stop display the next bus arrival in minutes, so you are never guessing. If a bus is more than 20 minutes out during normal hours, that is unusual and you can flag a lot attendant or call the parking operations line posted at the shelter.

Late-night travelers on early morning departures should plan for the 25-minute overnight interval. If your flight departs at 5:00 AM, add at least 30 minutes of shuttle buffer on top of your normal security time. TSA PreCheck can help you move faster through security once you reach the terminal — worth enrolling if you fly frequently.

BWI Long Term Parking Shuttle vs. Off-Airport Parking Shuttles: Which Is Better?

The on-airport BWI long term parking shuttle and off-airport lot shuttles both run free service, but they differ in frequency, coverage, and price. Here is a direct comparison based on current verified data.

Off-airport lots like FastPark 2 and The Parking Spot run shuttles every 5–10 minutes — more frequent than the on-airport long term shuttle during peak hours. FastPark 2 is also covered, which matters on rainy Maryland mornings. That said, the on-airport long term lots offer direct MAA oversight, 24/7 security patrols, and surveillance cameras — reassuring for extended trips. For travelers prioritizing price and shuttle speed, off-airport is worth a look. Our airport parking near BWI guide covers all the off-airport options in detail.

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

Getting from the long term lots to the BWI terminal is straightforward. The shuttle drops you at the upper level departures roadway, directly in front of the terminal entrance. From there it is a short walk inside to the airline check-in counters and security checkpoints.

BWI has five concourses — A through E — all connected inside the secure zone. The January 2026 opening of the $520 million Concourse A/B Connector (the largest capital project in BWI history) now gives passengers a direct single-level route between Concourses A and B, which is particularly useful for Southwest Airlines travelers who dominate those gates. Once you clear security, navigating between concourses is easier than ever.

For travelers with heavy luggage, ask the shuttle driver for assistance loading and unloading bags — this is standard practice and expected. If you use a wheelchair or need accessibility accommodations, accessible spaces are available throughout Long Term Lots A and B, and the shuttle buses accommodate mobility devices. The closest accessible spaces overall are in the Hourly and Daily Garages, but long term lot accessibility is solid for most needs.

Tips for Using the BWI Long Term Parking Shuttle Without Stress

A little preparation makes the shuttle experience much smoother. These tips come from analyzing common traveler pain points at BWI's long term facilities.

• Note your exact parking space: Write down the row letter and section number before you walk away. The lots are large — returning tired after a trip, this detail saves real time.
• Build in 30 minutes before security: Account for walking to the shelter, waiting for the shuttle, the ride, and the walk from the drop-off to your gate. Add more time during holidays.
• Use the real-time monitor: The digital displays at shuttle shelters show next arrival times. If your monitor shows 12+ minutes and you have checked bags, use that time to organize your documents and boarding passes.
• Travel light when possible: The shuttle does not have overhead racks. Large rolling bags sit in the aisle or front area. If you have oversized luggage, position yourself near the front of the boarding queue.
• Arrive earlier during peak seasons: Summer weekends, Thanksgiving week, and spring break see the highest lot occupancy at BWI. Both long term lots can fill by mid-morning on busy Fridays.
• Consider TSA security screening guidelines when planning: Even with a fast shuttle, arriving at least 90 minutes before domestic departures is wise. Two hours for international flights.
• Reserve in advance: Booking through a service like Triply locks in your spot and often surfaces discounted rates versus walk-up pricing.

What Happens If the BWI Long Term Parking Lots Are Full?

During peak travel periods, both Long Term Lot A and Lot B can reach full capacity. BWI's digital signage system displays lot availability as you enter the airport road network — if you see "FULL" on the Long Term signs, you have options.

• Express Parking: At $14/day, this is the next step up. Located near the Cell Phone Lot on Scott Road (near I-195 and Aviation Boulevard), it also runs a free shuttle every 10–15 minutes.
• Daily Garage: At $16/day, the Daily Garage is closer to the terminal and can accommodate overflow. The shuttle or a short walk gets you there.
• Off-airport lots: If you know in advance that long term is likely full — say, around Thanksgiving — book an off-airport lot early. FastPark 2, The Parking Spot East, and The Parking Spot West all run free 24/7 shuttles and start at $7.50/day, often cheaper than the on-airport long term rate even on a normal day.
• Book ahead: Pre-reserving your long term parking spot removes all of this uncertainty. See our article on BWI long term parking coupons and deals for how to score advance-booking discounts.

The Maryland Aviation Administration manages all on-airport parking under a dynamic availability system. Lot status updates on the airport's real-time boards are generally accurate within a few minutes. If you are driving in from Glen Burnie, Linthicum, or Hanover and see full signs before you even reach the airport, it is worth calling ahead or checking the official BWI website before you commit to the drive.
