Does any bus go directly from Philly to Bel Air, MD (or another town in the northeast suburbs of Baltimore)?

Best I can find so far is Greyhound’s service from Philly to Aberdeen (which takes three times as long and costs twice as much as Greyhound’s Philly to Baltimore).

Do you know of any other lines—for example, one of the Chinatown lines—that goes from Philly directly to a stop in Baltimore’s northeast suburbs?
