Baltimore/Washington Thurgood Marshall Airport (BWI) functions as the region’s primary budget- and leisure-focused gateway, with a mix of legacy carriers and many low-cost airlines operating frequent flights. Located about 10 miles (roughly 20–30 minutes by car) from downtown Baltimore and around 30–45 minutes from central Washington, D.C., ground access includes MARC commuter trains or Amtrak from BWI Rail Station, light rail service, shuttle buses, taxis, rideshares and rental cars; transit trips typically take 30–60 minutes and can be relatively inexpensive compared with airport transfers in larger metro areas. Travelers will find competitive fares and a modern terminal footprint, though peak hours can mean longer security queues and less public-transport directness than some international hubs; it’s a practical choice for cost-conscious or regional travelers seeking straightforward connections.

Seattle–Tacoma International Airport (SEA) is the region’s primary international hub, serving both full-service carriers like Alaska and Delta and a range of domestic and international airlines. Located about 14 miles south of downtown Seattle, it’s typically reachable in 20–35 minutes by light rail or 20–40 minutes by car depending on traffic; light rail fares are usually in the low single-digit range while ride-shares and taxis vary more. SEA offers a balance of amenities and traffic, with comfortable lounges and multiple dining options but can be busy during peak hours. For budget-focused travelers, proximity to transit is a key plus; for those seeking simplicity, allow extra time for security and connections.
