Boston Logan International Airport (BOS), located in East Boston, Massachusetts, is New England’s largest and busiest airport, serving more than 40 million passengers annually. Operated by Massport (Massachusetts Port Authority), Logan acts as a major hub for Delta Air Lines and JetBlue Airways, offering direct flights to over 120 domestic and international destinations.

With four main passenger terminals (A, B, C, and E), Boston Logan balances convenience and global connectivity. It’s widely recognized for its clean layout, energy-efficient facilities, and modernized terminals that provide an exceptional passenger experience.
