List of Southwest Airlines destinations

However, at Southwest's focus cities, the percentage of connecting passengers can reach 30 percent.

This agreement gave the airline the capability to begin flying to destinations outside of the United States.

This was followed by the first international flights which began on July 1, 2014, to Aruba (AUA), Montego Bay, Jamaica (MBJ) and Nassau, Bahamas (NAS).

Southwest built a 5-gate international terminal at William P. Hobby Airport that opened in 2015.

Southwest is the sole occupant of Terminal A and it invested significantly in the creation of the extension.
