Airlines Operating From BWI

Hot Tip: BWI has a useful search tool to check which destinations you can fly to from the airport and the airlines that operate the route.

BWI Airport Terminal

BWI has a main terminal building and 5 concourses. The terminal is a U-shape with the parking garage in the center and the airport road system and ground transportation services surrounding the parking garage.

The ticketing area is located on the upper level along with the security checkpoints that lead into the airside concourses. The main terminal building consists of 2 levels.

Terminal Upper Level

The upper level of the main terminal building houses the ticketing desks and a selection of restaurants and cafes, including Sky Azure, with an observation gallery.

Passengers can reach the upper level directly from the daily parking garage by walking across the skywalk bridges or from the lower level curbside by riding the elevator or escalators.

Access to the 4 security checkpoints is from the upper level with 3 checkpoints available for Concourses A, B, and C and 1 for Concourse D. Keep in mind that Concourses D and E are not linked airside with Concourses A, B, and C.

Terminal Lower Level

Arrivals for all concourses are located on the lower level, with international arrivals located near Concourse E.

A few cafes and shops are located on this level, along with the USO Lounge. The lower level of the terminal is accessible from the hourly parking lot via an underground tunnel, and ground transportation is located outside of the terminal buildings in designated areas.

Concourses A, B, and C

Concourse A has 16 gates numbered A1 to A16 and Concourse B has 15 gates numbered B1 to B15. Flights from both concourses are solely operated by Southwest Airlines.

Concourse C has 14 gates numbered C1 to C14 with flights operated by Southwest Airlines, American Airlines, and Contour Airlines.

The 3 concourses are accessible from any of the 3 security checkpoints located on the same side of the terminal building, and all have a good selection of shops, bars, and restaurants.

Concourses D and E

Concourse D has 22 gates numbered D1 to D5, D7, D8, D10 to D16, D20 to D26, and D29. Many airlines operate from Concourse D, including Alaska Airlines, and Boutique Air.

Concourse D is accessible through the D/E security checkpoint, so passengers have access to the amenities of both Concourses D and E. The Club at BWI is located in Concourse D near gate D10 and a Roam Fitness gym is just after the security checkpoint. If you’re flying Southwest or American, you can’t access the Club at BWI without going through security at Concourses D or E, so keep this in mind if you wish to visit the lounge.

Concourse E is the main international concourse with flights from British Airways, Condor, and Southwest Airlines. The concourse has 5 gates numbered E1, E3, E4, E6, and E8, and a small selection of cafes and restaurants (more available to passengers in Concourse D).

The Chesapeake Club Lounge is for eligible Oneworld passengers and is located on the upper level.

Interterminal Transportation

Walking

Baltimore/Washington International Airport is not a huge airport, so there are no trains or airside shuttles for connections. Passengers are required to walk from the main terminal to their concourse, and if connecting between the A/B/C concourses to the D/E concourses, they must re-clear security.

BWI promotes its cardio walking trails around the airport (with defibrillators on route) and has 2 1-kilometer routes — 1 from either end of the main terminal and 1 that runs the full length of Concourse A to Concourse B.

• Checkpoint C: 4 a.m. to 9:30 p.m

BWI Car Parking Information

Official Airport Parking

Short-Term Parking

The hourly parking garage offers the closest and most convenient parking to the main terminal building.

The garage uses smart parking technology that guides drivers to a space with a green light, and once parked, passengers can access the terminal via the climate-controlled bridges. Parking is $4 per hour and $22 per day.

Long-Term Parking

The daily parking garage is located on Terminal Road and Scott Drive opposite the express lot. Shuttles operate between the parking garage and the airport every 8 to 10 minutes. Daily parking costs $12.

The express parking lot is the second cheapest option available at BWI at $10 per day.

Once passengers have parked, a shuttle bus will collect you and your luggage from your parking bay and transport you to the terminal building. The express lot is located opposite the daily garage at Terminal Road and Scott Drive.

The A and B long-term parking lots offer the most cost-effective parking at the airport ($8 per day) and are located at MD 162 (Aviation Boulevard) between S. Camp Meade Road and Andover Road. Courtesy shuttles run between the airport and the parking lots.

Pickup or Drop-Off Parking

Visitors picking up passengers may use the cell phone waiting lot until the passenger is ready for curbside pick-up. Visitors may wait in the lot for up to 1 hour and may not leave their vehicles during this time.

The cell phone waiting lot is located on Scott Road, next to the daily parking garage entrance.

Off-Site and Hotel Parking

It’s pretty standard to be able to get cheaper airport parking with off-site parking lots, but at BWI, there’s not much savings to be had!

Daily parking starts at around $7 by booking with a third-party site such as airportparkingreservations.com. With official long-term parking available for just $1 more per day, we think it’s worth saving yourself the journey and parking on airport property (unless you’re booking a hotel and parking deal).

Parking for Passengers With Disabilities

Disabled parking is available in all of the official airport parking lots, and all parking shuttle buses are wheelchair accessible.

Airport Hotels

Top 3 Hotel Stays Using Points

The Westin Baltimore Washington Airport – BWI is less than 3 miles from the Baltimore/Washington International Airport and offers a free airport shuttle for your convenience. The hotel also offers a fitness center and indoor pool, and Marriott Bonvoy members with Platinum Elite status or higher can enjoy free breakfast in the executive lounge. The points needed will largely depend on the time of year that you visit, but expect 20,000 to 30,000 points per night.

The DoubleTree by Hilton offers close proximity to the airport, a free shuttle, an onsite restaurant, an outdoor pool, and a 24-hour fitness center. For award nights, keep in mind that Hilton no longer publishes an award chart and uses a dynamic pricing model for all of its hotels. Nights at this hotel often cost between 25,000 and 30,000 points per night.

An indoor pool, a 24-hour fitness center, a bar/lounge, a free airport shuttle, and complimentary breakfast are available to all guests of the Hyatt Place Baltimore/BWI Airport. Better yet, the hotel is just a Category 1 hotel in the World of Hyatt program so it costs just 3,500 to 6,500 points for a free night!

Final Thoughts

With Southwest Airlines accounting for over 70% of BWI’s passenger traffic, it’s not surprising that the airport has recently expanded its A terminal to the tune of $60 million. The expansion, which opened in May of 2021, includes 5 new gates, new restrooms, retail stores, and restaurants.

BWI was previously ranked as one of the top 10 best U.S. airports in the Condé Nast Traveler’s 2018 Readers’ Choice awards. The accolade was due to the airport’s convenient transit access, efficiency, and amenities, such as bicycle rental to accompany a 12-mile cycling trail around the airport, restaurants, and an observation deck. While BWI no longer holds this honor, it is the busiest airport in the Washington, D.C., metro area — a testament to the volume of passengers that choose the airport for its services and options.
