Martin State Airport

Martin State Airport (KMTN) sits in Middle River, Maryland, 8 miles northeast of downtown Baltimore. The field handles modest commercial service (very limited charter / commuter) and a meaningful flow of business aviation for the Baltimore-Washington corridor, particularly favored by operators based in the eastern Baltimore suburbs and the Aberdeen / Bel Air corporate corridor. The primary runway 15/33 is 6,997 feet — comfortable for heavy and ultra-long-range business jets at typical East Coast stage lengths. Atlantic Aviation operates the FBO. The airport is co-located with the Maryland Air National Guard, which adds some procedural quirks but doesn't constrain civil ops. Field elevation is 23 feet, no density-altitude concerns. The dominant operational considerations are East Coast winter weather (snow, freezing rain), summer thunderstorms, and the proximity to the busy Baltimore-Washington class B airspace structure. KMTN makes sense for charter into the Baltimore-northeast Maryland market specifically — for the DC metro, KIAD or KJYO are the standard answers; for downtown Baltimore, KBWI is the commercial alternative. Ground time to downtown Baltimore is 20–25 minutes; Aberdeen and the Bel Air corporate corridor are 20–30; downtown DC is 65–90.
