General Edward Lawrence Logan International Airport, (IATA: BOS, ICAO: KBOS) in the East Boston neighborhood of Boston, Massachusetts, is one of the 20 busiest airports in the U.S., with over 27 million passengers a year. It serves as a focus city for American Airlines, Delta Air Lines, US Airways, and JetBlue Airways. Continental Connection also operates a small regional hub at Logan.

Since September 11, 2001, Boston has implemented exceptionally strict security at some of its airports, especially Logan and Hanscom field. Because of this and Boston's location as the closest U.S. port to Europe, it is one of the main destinations for airliners that experience security breaches or disturbances while enroute to the U.S., though in many cases, planes are diverted to Halifax or other Canadian airports instead.
