Passenger traffic at Seattle-Tacoma International Airport, which increased at a pace last year swift enough to make it the nation’s fastest-growing major airport, is continuing upward this year at an even faster pace.
The number of domestic and international passengers handled at the airport in January, the latest month for which statistics have been published, grew by nearly 301,000 in January. The increase over the same month in 2014 was 11.92 percent.
International traffic jumped by 12.92 percent in 2015’s first month. That figure was 26,450 over the same month last year. Domestic traffic increased by 11.82 percent, or 264,475 passengers, over January 2014.
Sea-Tac has been the focus of major capacity increases in the last year with Delta Air Lines and Alaska Airlines, the No. 2 and No. 1 most used airlines at the airport, adding the most flights.
Delta is increasing its daily schedule this year from 85 flights a day to 126. Alaska is branching out to new nonstop cities throughout the country.
Delta’s schedule increase is driven in part by the need to feed its new group of international flights originating at the airport. The Atlanta-based airline has made Sea-Tac a West Coast hub for international flights with nonstop service to Hong Kong, Seoul, Beijing, Shanghai and Tokyo’s two airports. In Europe, Delta is flying to London, Amsterdam and Paris from Sea-Tac.
Last year Sea-Tac saw its passenger traffic increase by 7.7 percent to 37,497,941 passengers. No other major airport in the U.S. saw such a large increase in passengers.
