If the name change is approved, SFO would be the first airport in the United States named after an openly gay person, said Stuart Milk, Harvey Milk's nephew and a gay rights activist.

Milk, one of the first gay people elected to hold office in the United States, was shot and killed by a former politician in 1978. Mayor George Moscone was also killed.

Forty-one million passengers use SFO every year, and 68 countries where homosexuality is illegal are serviced by SFO flights, Stuart Milk said. That would send a powerful message, he said.
