The terminal's first expansion project was completed in the summer of 2015. It added an enlarged customs and immigration facility on the arrivals level capable of processing more than 600 passengers per hour, two domestic baggage claim belts, and an enlarged security checkpoint on the ticketing level. In 2019, an addition to the east side of the terminal added nine new gates, increasing the total number of gates from 25 to 34. These gates are spaced farther apart, to accommodate additional flights operated by larger aircraft. and Gates 1+3 and Gates 2+4 are able to act independently of each other when accommodating narrow body aircraft, or as one gate's Door A and Door B in a dual jetbridge configuration when larger, wide-body aircraft arrive providing boarding options. The number of flexible-use gates that can accommodate both international and domestic flights increased from two to six.
