Bellingham International Airport (IATA: BLI, ICAO: KBLI, FAA LID: BLI) is located three miles (5 km) northwest of Bellingham, in Whatcom County, Washington, USA.

Due to the close proximity to Canada, the Bellingham International Airport functions somewhat as a reliever airport to the Vancouver International Airport in Canada. On the Allegiant Air website the airport is referred to as Bellingham/Vancouver.

On March 1, 2008, Allegiant Air opened up their sixth base at Bellingham International Airport. The airline now currently bases two McDonnell Douglas MD-80 aircraft in Bellingham as part of the expansion.
