How Much Does BWI Long Term Parking Cost Per Day?

BWI long term parking costs $11 per day as of 2026, per the Maryland Aviation Administration. This rate applies to both Long Term Lot A and Long Term Lot B. There is no weekly cap or monthly rate published for these lots — you pay $11 for each calendar day your vehicle is parked.

Here is how the BWI long term parking per day rate stacks up against every other on-airport option, based on official BWI published rates (checked on bwiairport.com in October 2026):

The rate increase that took effect July 1, 2024 was the first adjustment to BWI parking prices since 2009. The Maryland Aviation Administration noted that the revenue funds capital improvements — including the $520 million Concourse A/B Connector, which opened January 9, 2026 as the largest capital project in BWI history. For a deeper look at what drove the rate change, see our article on the BWI long term parking price increase and current rate guide.

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

Long Term Lot A and Long Term Lot B are both open-air, self-park lots located on the south side of the BWI terminal complex. They sit off MD Route 170 (Aviation Boulevard) and are accessible via Interstate 195, the primary airport access road. Arriving from I-95, take I-195 east and follow signs for Long Term Parking.

Both lots are uncovered surface lots. They are large — BWI's total on-airport capacity is approximately 22,000 parking spaces across all facilities, per official airport data. The lots are well-lit and staffed. Accessible parking spaces are available in both lots; however, the closest ADA spaces to the terminal are in the Hourly and Daily Garages if mobility is a concern.

GPS tip: Navigate to BWI Long Term Parking, Linthicum, MD 21090 for the most reliable routing. Once you exit your vehicle, note your lot letter (A or B) and your row number — the lots are large, and many travelers forget their exact spot. Snap a photo with your phone before heading to the shuttle stop.

How Does the BWI Long Term Parking Shuttle Work?

The free BWI long term parking shuttle runs continuously between Lots A and B and the terminal. Shuttles depart every 10-15 minutes during normal hours and every 25 minutes between 1 AM and 5 AM, per BWI's published shuttle information. The ride to the terminal takes around 5-10 minutes depending on traffic and stops.

When you arrive at the lot, look for clearly marked shuttle stops within each section. The shuttle is free — no tip required, no fare collected. On your return, pick up the shuttle from the lower level of the terminal at the designated Ground Transportation area. The same free shuttle also connects the terminal to Express Parking, the Daily Garage, and the BWI Rail Station (MARC/Amtrak).

Plan to add at least 20-30 minutes to your pre-flight timeline to account for parking, the shuttle, and walking from the terminal drop-off to your concourse. If you have TSA PreCheck, security moves faster — TSA PreCheck enrollment is one of the best ways to offset the extra time a remote lot adds to your morning.

BWI Long Term Parking vs. Off-Site Parking: Which Is Cheaper Per Day?

The five off-site lots Triply sells near BWI beat the on-airport long term rate by about 24% to 44%, running about $6 to $8/day against $11/day on-airport. Shuttle service differs by lot: Doubletree Baltimore, The Westin and Sheraton Hotel run 24 hours, while Country Inn & Suites and Clarion Hotel BWI North have gaps in the day. Here is the full comparison (airport rates checked on bwiairport.com in October 2026):

Among the five, Doubletree Baltimore (890 Elkridge Landing Rd) is the cheapest at about $6/day, listed 2.2 miles out, with a shuttle that runs 24 hours; register your car at the front desk for a dashboard tag. Country Inn & Suites (1717 W Nursery Rd) is the closest at 1.7 miles, but it has no shuttle from noon to 4 PM, so check your flight time. The Westin and Sheraton Hotel sit next to each other on Old Elkridge Landing Rd, both list a free 24-hour shuttle with online booking, and cost about $7 and $8/day. Clarion Hotel BWI North (about $8/day, 3 miles out) is the farthest, and its shuttle runs only 4 AM to 10 AM and 5 PM to 11 PM.

How Much Will You Pay for Multiple Days at BWI Long Term Parking?

BWI long term parking charges a flat $11/day, with no weekly cap. Here is roughly what you will pay for common trip lengths, compared with the cheapest off-site lot Triply sells, Doubletree Baltimore (estimates at about $6/day):

On a two-week trip, choosing Doubletree Baltimore over BWI's on-airport long term rate saves you about $68. For shorter trips of three to four days, the savings are smaller (about $15 on three days), so the convenience of being on-airport may outweigh the difference for some travelers. Triply bills a 7-night stay as 8 days, so the real 7-night checkout at Doubletree Baltimore is $49.27 with no tax added, still well below a week in Long Term at $77. Our BWI 4-day parking guide breaks down the full cost comparison for that specific trip length.

How Do You Reserve BWI Long Term Parking in Advance?

On-airport Long Term Lots A and B do not require advance reservations. You drive in, take a ticket, park, and pay when you exit. No booking system, no confirmation number. Availability is generally strong given the large lot capacity, but during peak holiday travel, lots can fill up — particularly around Thanksgiving and major summer travel weekends.

If you want to reserve a space ahead of time, book an off-site lot in advance on Triply, with free cancellation with a full refund up to 24 hours before check-in. Steps to reserve off-site BWI long term parking:

1. Go to Triply's BWI parking search and enter your travel dates.
2. Compare rates, shuttle hours and distance across the five lots Triply sells.
3. Select your lot and complete the booking. You will receive a confirmation email.
4. On departure day, drive to the lot and check in the way your lot asks (at Doubletree Baltimore, register the car at the front desk for a dashboard tag; at Country Inn & Suites, park behind the hotel and register at the front desk), then board the shuttle.
5. On return, follow your lot's pickup instructions: at The Westin, Sheraton Hotel, Country Inn & Suites and Clarion Hotel BWI North you call the hotel for pickup (Country Inn & Suites from airport pickup zone 7, 48 or 60; Clarion from door 14 on the 2nd level near Spirit Airlines).

Booking in advance holds your space at the rate you booked. If you find a promo code or discount for BWI long term parking, our article on BWI long term parking coupons and best deals has the latest offers worth checking before you book.

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

BWI Long Term Lots A and B are self-park, open-air facilities. A few key rules apply. Oversized vehicles — including large trucks, RVs, and vehicles with rooftop cargo — may not fit in standard spaces and should contact BWI parking operations before arrival. The lots accept cash, Visa, Mastercard, American Express, Discover, and contactless payment at the exit. There is no requirement to pre-pay.

Accessible parking spaces are available within both lots. If you need the closest ADA-accessible spaces to the terminal, the Hourly and Daily Garages offer the nearest accessible spots with direct or near-direct terminal access. Check BWI's official long term parking page for current operational notices before you travel.

There is no published grace period or minimum charge beyond the first hour. If your plans change, you can exit within a short window without paying a full day's rate — but confirm current grace period rules at the exit booth, as policies can vary. Review TSA security screening guidelines alongside your parking plan to make sure your overall airport arrival timeline works.

Tips for Saving Money on BWI Airport Long Term Parking Per Day

Getting the best BWI long term parking per day rate takes a few minutes of planning. Here are the most effective strategies, based on our analysis of current rates across all verified BWI parking options:

• Book off-site in advance: Doubletree Baltimore starts at about $6/day, 44% below the on-airport long term rate, and the other four lots Triply sells run about $7 to $8/day (24% to 34% below). Booking ahead holds your space at the rate you booked.
• Match the shuttle to your flight: Country Inn & Suites has no shuttle from noon to 4 PM or midnight to 4:30 AM, and Clarion Hotel BWI North has none from 10 AM to 5 PM or 11 PM to 4 AM. Doubletree Baltimore, The Westin and Sheraton Hotel run 24 hours.
• Look for a free shuttle: The Westin and Sheraton Hotel both list a free shuttle with online booking, and neither requires a hotel stay.
• Consider the BWI Rail Station Garage if you use MARC: At $12/day with a free shuttle, it bridges the gap between long term and daily rates, and the MARC Penn Line connects BWI to D.C. in about 45 minutes for $8.
• Add TSA PreCheck to your routine: The time you save at security partly offsets the longer shuttle commute from a remote lot. TSA PreCheck enrollment runs $78 for five years.
• Before driving, check traffic: I-195 and I-95 can back up during peak morning hours. Use the Waze live traffic map to time your departure and avoid stress.

BWI long term parking per day at $11 is a solid value for on-airport convenience. But the off-site lots Triply sells, from about $6/day, cost less per day than every on-airport lot, and the savings grow with trip length, especially on trips of five days or more. Find and book the best BWI long term parking rate for your trip on Triply and compare all options in one place.

Compare BWI parking rates. Doubletree Baltimore, the lowest-priced BWI lot Triply sells at about $6/day, costs about 62% less per day than the airport's $16 Daily Garage.
