How Much Does BWI Long Term Parking Cost? (2024–2026 Rates Explained)
BWI Long Term Parking costs $11 per day with no hourly rate — you pay the flat daily maximum each day you park. According to the Maryland Aviation Administration, these rates took effect on July 1, 2024 — the first increase since 2009. Before that date, the long term rate was lower, so travelers who haven't parked at BWI recently should budget for the updated pricing.
Here's how all on-airport options compare at a glance (verified June 2026, per BWI's official parking page):
| Parking Option | Daily Rate | Best For |
|---|---|---|
| Long Term Lots (A & B) | $11/day | Multi-day trips, budget travelers |
| BWI Rail Station Garage | $12/day | MARC/Amtrak rail connections |
| Express Parking | $14/day | Quick access, Scott Road location |
| Daily Garage | $16/day | Covered parking, closer to terminal |
| Hourly Garage | $30/day max ($4/hr) | Short stays, drop-offs, pickups |
The Long Term Lots are consistently the most affordable on-airport option. For every additional day past day one, you save $5 vs. Express Parking and $19 vs. the Hourly Garage. Those savings add up fast on a 7- or 14-day trip.

How to Use the BWI Long Term Parking Calculator
The BWI long term parking calculator works with simple math: daily rate × number of days = total cost. Since BWI Long Term Lots charge a flat $11/day with no hourly billing, you don't need to worry about partial days — you pay the full daily rate for each calendar day your car is in the lot.
Follow these steps to get your accurate total:
- Note your drop-off date and time. The clock starts when you enter the lot.
- Note your return date and time. Each new calendar day triggers the daily charge.
- Count the number of days. Even if you return early on day 5, you typically owe for day 5.
- Multiply by $11. That's your BWI Long Term Parking total.
- Compare to alternatives. Use the table in the next section to see if off-site lots save you money.
Example: You fly out Monday morning and return Sunday night. That's 6 nights but 7 calendar days in the lot. At $11/day: 7 × $11 = $77 total. The same logic applies to every duration in the cost table below.

Key insight: On a 7-day trip, choosing The Parking Spot over BWI Long Term Lots saves you $24.50. Over 14 days, that gap grows to $49. Both options include a free shuttle, so the convenience is nearly identical. For business travelers on 3-5 day trips, the savings are smaller — but still real.
Long Term Lot A vs Lot B: What Is the Difference?
BWI operates two Long Term Parking lots — Lot A and Lot B — both charging the same $11/day rate. Both are surface lots connected to the terminal by the same free shuttle service. The differences are minor but worth knowing before you park.
- Rate: Identical — $11/day at both lots
- Surface type: Both are open-air, uncovered surface lots
- Shuttle access: Both served by the same BWI Long Term Parking shuttle circuit
- Shuttle frequency: Every 10-15 minutes during normal hours; every 25 minutes between 1–5 AM
- Accessibility: Accessible parking spaces are available in both lots
- Location tip: Note your exact lot and row when you park — these are large surface lots and it's easy to lose your spot
For a deeper look at Lot A specifically — including location details and directions — see our guide on BWI Long Term Parking A: 2026 Rates, Lots & Tips.
Pro tip: Take a photo of the nearest lot marker or shuttle stop sign when you park. On large surface lots, this saves serious time when you return.
How Does BWI Long Term Parking Compare to Off-Site Options?
Off-site lots near BWI are cheaper than Long Term Lots on every trip length, based on current published rates. The trade-off is a slightly longer shuttle ride — but not by much.
| Facility | Rate/Day | Shuttle Time | Coverage | Savings vs. BWI Long Term (7 days) |
|---|---|---|---|---|
| FastPark 2 (BWI) | $7.50 | ~2 min | Covered | $24.50 |
| The Parking Spot (East) | $7.50 | ~5 min | Uncovered | $24.50 |
| The Parking Spot (West) | $7.50 | ~5 min | Uncovered | $24.50 |
| DoubleTree by Hilton BWI | $7.95 | ~8 min | Uncovered | $21.35 |
| FastPark & Relax (BWI) | $8.00 | ~3 min | Covered available | $21.00 |
| BWI Long Term Lots | $11.00 | ~10-15 min | Uncovered | — |
Based on our analysis, off-site lots like FastPark 2 and The Parking Spot offer shuttle service every 5-10 minutes — actually more frequent than the on-airport shuttle during overnight hours. FastPark 2 is only 2 minutes from BWI, making it hard to argue against on convenience alone.
For a full breakdown of options just outside the airport perimeter, see our guide on airport parking near BWI — it covers every verified off-site lot with directions and booking tips.
The DoubleTree by Hilton BWI Airport lot is worth a look for overnight travelers. At $7.95/day, it undercuts BWI Long Term Parking while offering hotel amenities if you need a room before an early flight. Our full DoubleTree BWI airport hotel parking guide has the details.
How Often Do BWI Long Term Parking Shuttles Run?
The BWI Long Term Parking shuttle runs every 10-15 minutes during normal hours, per official airport data. Between 1:00 AM and 5:00 AM, frequency drops to every 25 minutes. The shuttle is free and connects Long Term Lots A and B directly to the terminal — no additional transfers required.
- Normal hours: Every 10-15 minutes
- Overnight hours (1–5 AM): Every 25 minutes
- Cost: Free
- Service: 24/7, every day of the year
- Also serves: Express Parking, Daily Garage, and BWI Rail Station Garage
If your flight departs or arrives between 1 and 5 AM, add extra buffer time. A 25-minute shuttle wait can make the difference between a stressful and smooth departure. Arriving at the lot 45-60 minutes before you need to be at the gate is smart planning for those early-morning flights.
Planning to pick someone up? The Cell Phone Lot on Scott Road (across from Express Parking, near I-195 and Aviation Boulevard) is free for up to one hour. It's a better option than circling or paying the Hourly Garage rate of $4 per hour. For the full step-by-step on returning from the long term lots, our BWI long term parking pick-up guide walks you through it.
Is It Cheaper to Book BWI Long Term Parking in Advance?
Booking ahead doesn't change the on-airport rate — BWI Long Term Lots charge $11/day whether you reserve ahead or pay on arrival. However, off-site lots frequently offer pre-booking discounts, making advance reservations the smarter move for most travelers.
Here's why booking early matters:
- Off-site lots sell out around Thanksgiving, July 4th, spring break, and summer peak season
- Pre-booking locks in the advertised rate — prices can rise as availability drops
- Coupons and promo codes are sometimes available for off-site lots when you book online
- Free cancellation is standard at most verified lots — so there's no risk to reserving early
- BWI's on-airport lots accept walk-ins — but the lot can fill during peak periods, especially Long Term Lot A
For coupon codes and pre-booking deals on BWI long term parking, check our up-to-date BWI long term parking coupon guide — it lists the best current discounts in one place.
One more consideration: BWI completed a $520 million Concourse A/B Connector project on January 9, 2026 — the largest capital project in the airport's history. Smart parking guidance systems are also being rolled out across the facility. As these upgrades continue, the on-airport parking experience is improving, though rates remain the same.
Before you drive to the airport, check real-time traffic on Waze. BWI sits at the intersection of I-195, I-95, and the Baltimore-Washington Parkway — all of which can back up during rush hour or after local events. Building in an extra 20-30 minutes on travel days protects your departure time.
Accessibility note: ADA-accessible parking is available in both Long Term Lot A and Lot B. The closest accessible spaces for travelers with mobility needs are in the Hourly and Daily Garages, which are a shorter walk to the terminal. Plan accordingly based on your specific needs.
Bottom line on the BWI long term parking calculator: At $11/day, BWI Long Term Parking is the cheapest on-airport option — but off-site lots at $7.50–$8/day beat it on price every time. Run your numbers using the table above, factor in how much the shuttle wait matters to you, and book ahead to secure your rate.
