Complete Guide to Airport Timing
Baltimore/Washington International Thurgood Marshall Airport (BWI) serves the Baltimore-Washington metropolitan area and is a major hub for Southwest Airlines. Located between Baltimore and Washington DC, BWI offers convenient access to both cities.
How Early Should I Arrive at BWI for a Domestic Flight?
Arrive 2 hours before departure for domestic flights. This allows time for navigating to the airport, parking, check-in, security screening, and reaching your gate. BWI's security is generally efficient, especially compared to Washington Dulles (IAD).
How Early Should I Arrive at BWI for an International Flight?
Arrive 3 hours before departure for international flights. International gates require extra time for check-in procedures and security screening.
When is BWI Most Busy?
BWI's busiest periods are 5am-8am and 4pm-7pm. Security lines during these times typically average 30-40 minutes when Southwest flight banks are departing. Off-peak hours see much shorter waits, often under 20 minutes.
How Much Time Should I Allow for Traffic to BWI?
Traffic on I-95, I-295 (Baltimore-Washington Parkway), and MD-295 can create delays during rush hour. From downtown Baltimore, allow 20-30 minutes. From downtown Washington DC, allow 45-60 minutes during peak times. MARC and Amtrak trains provide rail access.
Which BWI Terminal Should I Go To?
BWI has one main terminal with 5 concourses (A, B, C, D, E) all connected post-security. Southwest dominates Concourse A. All passengers enter through the same terminal building for check-in and security, then proceed to their concourse. Check your gate's concourse when you check in.

BWI is generally efficient, but Southwest flight banks create peak congestion periods.
How long does security take at BWI?
Average security wait time is 20-30 minutes. During peak hours (5-8am and 4-7pm), expect waits of 30-40 minutes when Southwest flight banks are departing. BWI has one main security checkpoint serving all concourses. TSA PreCheck can save 10-15 minutes. Check the MyTSA app for current wait times before you leave. BWI is generally more efficient than Washington Dulles (IAD).
Can I take the train to BWI?
Yes! Both MARC (Penn Line) and Amtrak provide service to BWI Rail Station, which is connected to the terminal by a free shuttle bus (runs every 10 minutes). From Washington DC's Union Station, Amtrak takes 20-30 minutes and MARC takes 35-40 minutes. From Baltimore's Penn Station, Amtrak takes 15 minutes and MARC takes 20 minutes. This is a reliable alternative to driving, especially during rush hour.
Is BWI better than IAD or DCA for DC area travelers?
BWI is often preferred for domestic flights and Southwest Airlines travel, despite being farther from DC than DCA (Reagan National). BWI typically has lower fares, less congestion than IAD (Dulles), and efficient security. DCA is most convenient for downtown DC but has slot restrictions. IAD is best for international flights but has longer security waits. For Baltimore residents, BWI is the clear choice. For DC residents, it depends on your specific needs and location.
