Boston Airport has four passenger terminals - A, B, C, and E. All flights to Boston from U.S. territories, Canada, and Ireland that is included as an exception of flights from destinations with U.S. Customs and Border Protection preclearance, all ingoing international flights arrive at Terminal E for customs screening because the other terminals do not have customs screening facilities.

Massport eventually plans to connect all terminals and gates post-security, thus providing seamless connections between flights from different terminals.

Terminal A was opened in 2005, and it was one of the most interesting buildings at Boston Airport. This Terminal was designed by HOK Architects; it is a global firm that designs all types of projects from large government and commercial buildings to residential and recreational facilities. The Terminal A is the first terminals that became LEED certified and the first certified terminal at a US airport. LEED certified buildings are energy efficient and responsible use resources like materials sourced from water usage or recycled materials. Terminal A is still trying to use every aspect to improve the energy efficiency and promote sustainability. The best improvement that was made and has a great impact is the solar trees at the top of the parking garage. Other important updates that have contributed to LEED certification include new wind turbines in terminal A’s offices and improvements to the roof and roadways of the terminal, which reduces the effect of heat island effect and stormwater runoff.
