Main terminal and concourses at BWI

🔍 What to expect

Cleanliness and maintenance

Overall terminal cleanliness at BWI is something many travelers praise. Floors and seating areas are well maintained, which creates a good first impression. However, some passengers mention that at peak times “restrooms can be a bit neglected,” with missing supplies and minor hygiene issues.

In the renovated areas of Concourses B and C you will find large, modern restrooms with occupancy indicators that tend to get very good feedback, while older sections can feel more basic or dated when the airport is particularly busy.

Signage and wayfinding

The airport does have generally clear signage, but some travelers—especially first-time visitors—have commented that wayfinding can be confusing in certain spots, particularly when connecting between concourses and ground transportation areas. During heavy traffic, this lack of clarity can create extra friction.

The biggest source of confusion is usually the practical split between the A–B–C and D–E sides: it is easy to pick the wrong checkpoint if you do not pay close attention to the signs, so it is worth confirming your concourse on the displays before heading for security.

Space and comfort

Most passengers appreciate the generous space in the terminals, which makes it easier to move around comfortably even at busy times. Seating areas are fairly well distributed and offer power outlets to charge devices, which is very useful if you are waiting for a connecting flight.

Even so, many reviews mention that outlets are not evenly spread across all gates and that some seating zones fill quickly, so it is smart to grab a seat with nearby plugs as soon as you reach your gate if you need to work or recharge devices.

Connectivity between concourses

Although connections between concourses are reasonably well designed, several passengers mention that distances can be long and tiring, especially if your layover is tight. The internal transportation options, like the “people mover”, help, but some travelers feel frequency could be higher to speed up transfers.

In practice, many travelers use the marked walking routes to move between areas, but if you are carrying heavy luggage, traveling with kids or have reduced mobility, the safest plan is to add a few extra minutes to any connection that involves crossing from one end of a concourse to another.

Accessibility

Travelers with special needs often praise accessible features such as adapted restrooms and ramps. That said, some people would like to see more staff present to offer assistance in key areas of the airport.

If you need wheelchair support or special assistance, it is best to request it in advance from your airline and arrive with plenty of time, as during very busy periods it may take a little longer for staff to reach you.

Rest areas and amenities

Some travelers say it would be useful to have more and larger quiet rest areas, separated from the noise of shops and restaurants. Current seating zones are functional, but many feel the quantity and layout of truly calm spaces could be improved.

For long layovers or tricky overnights, it is usually more comfortable to look for slightly tucked-away corners in the concourses rather than in the main hall, though you should keep in mind that lighting and noise make BWI less than ideal for sleeping landside.

Negative feedback

During certain renovation or construction phases, passengers have reported discomfort from crowded corridors or reduced seating areas. Fortunately, most note that once these works finish, the overall experience improves noticeably.

There are also reviews describing specific sections as old or poorly maintained compared with other major airports, reinforcing the idea that your experience at BWI depends heavily on which concourse you use and what time of day you are traveling.

⬆️ Upper level

The upper level of the main terminal building houses ticketing and check-in counters, restaurants and cafés, and an observation gallery. Passengers can reach the upper level directly from the daily parking garage via elevated walkways or from the lower-level curbside using elevators or escalators. Access to the four security checkpoints is from the upper level, with three checkpoints serving Concourses A, B and C and one for Concourse D. Keep in mind that the post-security areas for Concourses D and E are not connected to Concourses A, B and C.

If you are flying with Southwest, American or other airlines based in A, B or C, you can use virtually any of the checkpoints on that side, whereas for flights departing from D or E it is best to head straight to the D/E checkpoint to avoid unnecessary walking.

⬇️ Lower level

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

A few cafés and shops are found on this level, along with the USO Lounge (located in the Concourse E baggage claim area). The lower level of the terminal can be reached from the hourly parking garage via an underground tunnel, and ground transportation services are located outside the terminal buildings in designated areas.

The passenger pick-up area can become chaotic at peak times, with vehicles double-parked and lots of movement, so it is often better to coordinate pick-up at the cell phone lot or another agreed spot rather than having someone wait right at the curb for a long time.

🛫 Concourses

As mentioned above, BWI is made up of five concourses with boarding gates numbered from A to E.

Concourse A

Concourse A is fully operated by Southwest Airlines and has 11 gates (A1–A11). It offers the widest range of food and drink options of all concourses. It is directly connected to Concourse B, so from the lower level you can access all A and B gates.

For many frequent Southwest flyers, this is the most convenient area of the airport thanks to the strong dining offer and the feeling of a compact “hub” where it is easy to find something to eat before boarding.

Concourse B

Concourse B is also used exclusively by Southwest Airlines and has 14 gates (B2–B15). It has a good range of dining options, though fewer shops than its neighbor Concourse A. The two concourses are directly connected on the lower level.

A large share of BWI traffic is concentrated in A and B, so at peak times corridors and seating areas can be quite busy, but in return you almost always have something nearby if you want to grab a bite or a coffee.

Concourse C

Concourse C has 14 gates (C1 to C14), all located on the upper level. Airlines operating here include American Airlines and Southwest Airlines. Since it is on the same side of the terminal building, you can access this concourse as well as A and B from any of the three security checkpoints on that side. Food options are more limited than in A and B.

On the plus side, many travelers find the flow of people a bit calmer than in A/B, so it can be a good place to wait for your flight if you do not need as many dining choices.

Concourse D

Concourse D has 22 gates: D1–D5, D7, D8, D10–D16, D20–D26 and D29. It is used for domestic flights that are not operated by Southwest Airlines or American Airlines. It has the largest number of shops and dining venues and is home to one of the airport lounges (The Club BWI), located near gate D10.

If you fly with airlines other than Southwest or American, chances are you will depart from here, so it is worth getting familiar with walking times from security and remembering that the post-security D/E area is separate from A/B/C.

Concourse E – International terminal

Concourse E has five gates (E1, E3, E4, E6 and E8) and is located on the upper level. It is known as the International Terminal because it handles all international arrivals, but its official name is the Governor William Donald Schaefer International Terminal. There is just a small newsstand and one restaurant here, as it is directly connected to Concourse D, where passengers will find a much broader range of shops and dining. British Airways has a lounge in this concourse (Chesapeake Club Lounge). On the lower arrivals level, near baggage carousel 14, there is also a USO lounge (for military personnel only).

Keep in mind that if your international flight arrives late or at a time when few services are open, it may be worth walking over to D once you clear controls and collect your carry-on to find more food and shopping options.

🔁 Connections between concourses

Connections between concourses are on foot. Passengers must walk from the main terminal to their concourse, and if they are connecting between Concourses A/B/C and D/E, they must clear security again. BWI promotes cardio walking paths around the airport (with defibrillators along the way) and has two one-kilometer routes (about a 20-minute walk): the Terminal Loop runs along the public side of the upper level (the white-floor area before security) from the end of Concourse A to the far end of Concourse E, while the Concourse A/B Loop covers the secure area of Concourses A and B.

These routes are great if you have time to spare and want to stretch your legs, but if your priority is making a tight connection, it is better to stick to the most direct path and save the “cardio trails” for longer layovers.

The BWI Courtesy Shuttle is a free, high-frequency shuttle service that connects different locations around the airport.

Courtesy shuttle routes:

> Parking shuttle: between the main terminal and the long-term lots, Express Lot and Daily Garage. Frequency: every 10–15 minutes. > Amtrak/MARC shuttle: between the main terminal and the Amtrak/MARC rail station. Frequency: every 10–15 minutes (every 25 minutes from 1:00 a.m. to 5:00 a.m.). > Rental car shuttle: between the main terminal and the consolidated rental car center. Frequency: every 8–10 minutes (every 25 minutes from 1:00 a.m. to 5:00 a.m.).

Recent reviews mention slightly longer-than-ideal waits at peak times and crowded buses heading to the rental car center, so it is smart to add extra buffer time if you need to return a car before your flight or catch a train.
