Traveling to Baltimore by air is fairly simple. The main airport is Baltimore-Washington International Thurgood Marshall Airport (BWI), just south of town. BWI is easily reached by car, taxi, or light rail; for most agencies, rental cars are returned to lots off the airport premises.
BWI SuperShuttle provides van service between the airport and downtown hotels every half-hour from 4 am–midnight; travel time is about 30 minutes. The fare is $15 per person. Hotel vans, which operate independently of the hotels, take 30 minutes on average.
Carey Limousines provides sedan service, which costs $80; make reservations 24 hours in advance. Private Car/RMA Worldwide Chauffeured Transportation has sedans, limos, and vans; the cost to the Inner Harbor is about $40 for a sedan.
Airport Taxis stand by to meet arriving flights. The ride into town on I–295 takes 20 minutes; a trip between the airport and downtown costs about $35. Airport Taxi service is available only from BWI; for transportation to the airport, consult a local cab company such as Jimmy’s Cab Co. or Arrow Cab.
