Bradley International Airport comprises two terminal buildings, namely Terminal A and Terminal B. Terminal A acts as the main terminal and is currently operational at BDL. It accommodates almost all airport-related activities, like check-in counters, security checkpoints, and gates, along with amenities for most airlines serving the airport and American Airlines. Terminal B, on the other hand, no longer serves passenger operations. It was the original terminal building at BDL, eventually closing in 2010 before demolition in 2015-2016 to make way for future expansion. The airport is building a new Ground Transportation Center on the site of the old Terminal B.
