Seattle–Tacoma International Airport

The history of Seattle–Tacoma International Airport dates back to the late 1920s when the Port of Seattle and Port of Tacoma proposed a shared public airport. However, these plans were initially deferred due to legal concerns. In 1941, the state legislature authorized municipal corporations to establish aviation facilities, and in 1942, the Port of Seattle accepted a grant to construct a new airport to serve the Seattle area after the U.S. military took control of Boeing Field during World War II. The airport's first parking lot opened in 1955, and the United States Postal Service established an air mail terminal at the airport in 1957. Japan Airlines became the first international carrier to operate at Sea–Tac in 1959.

Today, Seattle–Tacoma International Airport offers a range of amenities for travellers, including live music, artisan shops, restaurants, and fast food options. The airport has also been recognized for its accessibility features and improvements that enhance the overall airport experience. The airport provides various parking options, including a 12,100-space garage, valet parking, and electric vehicle charging stations. Additionally, the airport is easily accessible via public transportation, with a Link light rail system connecting it to downtown Seattle and the University of Washington.

King County International Airport

The airport's proximity to downtown Seattle means that it regularly hosts celebrities, dignitaries, and sports teams. It has a unique environment, hosting numerous businesses, organisations, and public safety agencies. It also provides many educational and employment opportunities. The airport contracts with the King County Sheriff's Office for police services, with deputies wearing a mix of police and fire uniforms and driving King County International Airport Police patrol cars.

The history of King County International Airport dates back to 1928 when it was constructed and served as Seattle's primary airport until 1944. In 1935, the Federal Aviation Administration began investigating the construction of a new airport due to risks associated with the high ridge to the east of Boeing Field. In 1941, Galvin Airport (now Seattle-Tacoma International Airport) was built about five miles south of Boeing Field, changing its function to a significant regional general aviation and industrial airport. In 1946, West Coast Airlines operated scheduled passenger Douglas DC-3 services from the airport, and in 1954, the first Boeing 707 jet airliner prototype landed at Boeing Field, marking the beginning of the jet age in aviation.

Bellingham Airport

Bellingham International Airport (IATA: BLI, ICAO: KBLI, FAA LID: BLI) is a busy airport located approximately three miles (5 km) northwest of Bellingham, in Whatcom County, Washington. Covering 2,190 acres (886 ha) of land, it is the third-largest commercial airport in Washington. Bellingham Airport is a low-fare alternative to Vancouver International Airport, and an estimated 65% of its customers are from Canada. The airport is only 54 miles (87 km) from downtown Vancouver and 23 miles (37 km) from the Peace Arch Border Crossing, where Greater Vancouver starts.

The Works Progress Administration (WPA) began studying a potential airport for Whatcom County in late 1935 as part of a program to build airports in large Washington cities. A plan to build an airport west of Bellingham was endorsed by the Washington state WPA office by the end of the year and by the head office the following July. The airport was slowly returned to Whatcom County and redeveloped as a civil airport in the late 1940s. With rising costs and the need for repairs, Whatcom County sold the airport to the Port of Bellingham for one dollar in 1957.

Due to financial constraints, the Port of Bellingham could only resurface the longest runway (16/34). Runway 16/34 is still the only runway used as it provides adequate year-round wind coverage for aircraft servicing Bellingham. The airport closed runway 12/30 in 1986, and runway 2/20 was shut down in 1997. The two diagonal runways have fallen into disrepair, and their easternmost ends are used as taxiways between tarmacs and the sole remaining runway. Bellingham International Airport accommodates more than 800,000 travellers each year, serving the commercial, general aviation, and corporate air transportation needs of the region.

The airport is also a busy general aviation (GA) facility, with numerous flights oriented towards sightseeing in the San Juan Islands, Victoria in British Columbia, or the Canadian Gulf Islands. The majority of GA operations are commercial, including charters, flight training, transient flights, and private business operations. Bellingham International Airport serves as a port of entry for international travellers. GA facilities occupy about 20 acres (8.1 ha) south of the passenger terminal and include tie-down spaces, numerous hangars, and a dedicated GA terminal.
