Airways, and WestJet typically park at Boarding Area G. Boarding Area A is also used by domestic carriers Frontier Airlines, Sun Country Airlines, and Hawaiian Airlines. When all gates in an airline's designated international boarding area are full, the passengers will board or deplane from the opposite international boarding area. Aer Lingus, Flair Airlines, and WestJet operate from airports with United States border preclearance, allowing arriving passengers to skip the wait at customs and immigration when they arrive at SFO, and exit the airport from the departure level. The two main designations for the International Terminal are "I", and "INTL" (abbreviations for "International"). Oftentimes travel itineraries will say "T-I", and this has led to instances where passengers misinterpret the "I" as Terminal 1, especially since both Boarding Area A and Boarding Area G are used for a limited number of domestic flights. SFO Museum SFO Museum was created in 1980 as a collaboration between the San Francisco Airport Commission and the Fine Arts Museums of San Francisco and was the first museum in an international airport. It was accredited by the American Association of Museums in 1999, and contains both permanent artwork and temporary exhibitions in more than 20 galleries. The Aviation Museum and Library (officially, the San Francisco Airport Commission Aviation Library and Louis A. Turpen Aviation Museum) is located in the International Terminal, featuring a model of a DC-3.
