airline service from bellingham had a modest beginning. during the late 1970s and early 1980s, harbor airlines, a commuter air carrier based in washington, operated nonstop shuttle service to seattle/tacoma international airport with small britten-norman islander twin prop aircraft. by the mid 1980s, harbor air had been replaced by san juan airlines, a commuter air carrier based in bellingham which operated shuttle flights to seattle/tacoma with embraer emb-110 bandeirante turboprops and cessna 402 prop aircraft. san juan airlines continues to serve the airport at the present time.
