 In June 2012, Terminal A was opened and occupied solely by JetBlue Airways, making San Juan a focus city.When Terminal B was closed for renovations, four regional airlines were moved to Terminal D.

As of November 2018, JetBlue only uses four of the six gates in the terminal, unlike years before when it used all six.Gates A1 and A2 are used by other airlines such as Copa Airlines and Allegiant Air.
