Though Connecticut features limited airports serving commercial flights, few among them provides best connectivity to major cities of the state. Bradley International Airport and Tweed New Haven Regional Airport are the only two major airports with scheduled flights in Connecticut. Most of the other airports provide chartered flight services.
Danbury Municipal Airport, Hartford-Brainard Airport and Roberson Field Plainville are the reliever airports in the state. Groton New London Airport and Sikorsky Memorial Airport in Bridgeport have small passenger terminals and check in counters. Groton New London does not have commercial service airline currently. Bradley Airport in Windsor Locks is located at equal distance from Hartford and Springfield. It is the only airport in Connecticut that sees both national and international traffic. Tweed New Haven Regional Airport, also called HVN, has been witnessing a constant upsurge in the passenger traffic every year with the growing tourism and business activities in the state.
