The thrice-weekly service will use a Boeing 747 freighter. The flight to Asia is non-stop, but Asiana will return to PDX through Anchorage, Miami or Atlanta.

Officials expect to transport seasonal perishables — such as Oregon blueberries, cherries, Dungeness crab and oysters — on the route.

During a press conference announcing the new service, Oregon Governor John Kitzhaber said the Asiana flights will help generate $27 million a year in local business activity. He expects to see 80 more local jobs, as well. He also pointed out that the state's top three trading partners are Japan, Korea and China — locations that are all served by the new flights.

"For Portland businesses, nonstop air cargo service to Asia is absolutely critical in getting our goods to market," Portland Mayor Sam Adams said in a statement. “This is an important accomplishment for the Port of Portland and will translate into more trade and job creation for our region."

Local media reported that Asiana will receive more than $750,000 in incentives.
