The airport’s year-to-year declines in international traffic ranged from drops of 5% to 35% in each of the first five months of 2015.

Southwest Airlines began flying to Puerto Vallarta on June 7, which accounted for some of the 8% increase. It was already flying to Cabo San Lucas/Los Cabos.

The three busiest airlines were Southwest, with about 382,000 passengers; United, with about 116,000 passengers; and American, with about 113,000 passengers.
