The Bellingham International Airport will show off its new construction at a free open house from noon to 4 p.m., on Saturday, July 19.

The $38.6 million construction project, which began in 2008, included updates and additions to the gate lobby, baggage handling and baggage claim areas, the terminal, and the ticket lobby.

The project is paid for with airport revenue and passenger facility charges.

The terminal went from 27,000 square feet to 105,000 square feet and is now a quarter-mile long, said Mark Leutwiler, airport manager.

“A lot of times, people get through the door with their bags and they go, “oh wow,” Leutwiler said about the additions to the airport. “It’s a true pleasure to hear that.”
