How Much Will You Pay in Total? BWI Long Term Parking Cost by Trip Length

At $11 per day, your total BWI long term parking cost per day adds up quickly on longer trips. The table below shows your total cost at the on-airport rate alongside the cheapest available off-airport alternative.

On a two-week trip, choosing Doubletree Baltimore over the on-airport Long Term option saves you about $68. Real checkouts run a little higher than rate times days, because a 7-night stay is billed as 8 days: Doubletree comes to about $49, and every Triply BWI lot stays below the $77 you would pay for a week in Long Term. The July 2024 rate increase (from the previous rate to $11/day) was the first adjustment in 15 years, according to the Maryland Aviation Administration, so these are relatively fresh numbers that reflect current airport operating costs.

What Is the Difference Between BWI Long Term Lot A and Lot B?

Both Long Term Lot A and Lot B charge the same $11/day rate and are served by the same free shuttle system. The key difference is their physical location on the airport grounds, which affects walk distance and shuttle stop sequence.

How Does the BWI Long Term Parking Shuttle Work?

The free shuttle is the main connection between Long Term Lots A and B and the BWI terminal. According to official BWI airport data, the shuttle runs every 10-15 minutes during normal hours, and every 25 minutes between 1 AM and 5 AM.

Here is what to expect step by step:

1. Park your car and note your spot number and lot letter (A or B).
2. Walk to the designated shuttle pick-up area in your lot.
3. Board the free shuttle — no ticket or payment needed.
4. The shuttle drops you at the terminal departures level.
5. On return, pick up the shuttle at the Ground Transportation area on the terminal's lower level.

The shuttle also connects to Express Parking, the Daily Garage, and the BWI Rail Station — all on the same free system. For full details on shuttle pick-up zones and return procedures, our guide to the BWI long term parking shuttle pick-up covers every step. Plan to arrive at your lot with enough time before your flight — allow at least 30-40 minutes before your target security arrival time to account for parking, the shuttle ride, and any wait at the stop.

The Westin (about $7/day) and Sheraton Hotel (about $8/day) list free shuttles with online booking, also 24 hours, every 30 minutes. Country Inn & Suites and Clarion Hotel BWI North have gaps in shuttle service, so check their hours against your flight.

How to Save Money on BWI Long Term Parking

There are several practical ways to reduce your BWI long term parking cost per day, whether you stick with the on-airport lots or go off-site.

• Book off-airport: The five lots Triply sells near BWI run about $6 to $8/day, roughly $3 to $5 less per day than on-airport Long Term rates.
• Match the shuttle to your flight: Doubletree, The Westin and Sheraton run shuttles 24 hours, while Country Inn & Suites and Clarion have gaps in service.
• Book ahead: Reserve your spot online with free cancellation with a full refund up to 24 hours before check-in.
• Compare on Triply: Search BWI lots on Triply to see the five off-airport rates side by side.
• Check the real total: a 7-night stay is billed as 8 days, about $49 to $67 across Triply's BWI lots, still below a week in Long Term ($77).
• Avoid the Hourly Garage: At $6 per hour with a $30/day maximum, the Hourly Garage costs nearly three times the Long Term rate for stays over a day.

If you have TSA PreCheck, you can also shave time off your airport arrival — meaning you do not need to arrive as early, which can reduce same-day parking decisions made under pressure.
