Pillbox hats, Russian Cossack dresses and hot pants are returning to the nation’s airways thanks to a fashion flashback staged by Alaska Airlines flight attendants in celebration of the airline’s 75-year history.

The festivities kicked off with a runway fashion show in June 2007 at Seattle-Tacoma International Airport showcasing flight-crew uniforms including a 1950s-era skirt suit with pillbox hat; an arctic parka and ski pants worn during the 1950s and 1960s; a 1960s uniform inspired by Alaska Gold Rush fashions featuring a long red-velvet skirt and hat trimmed with ostrich feathers; a Russian Cossack red tunic and fur hat worn during the airline’s 1960s Cold War-era flights to the Soviet Union; and hot pants and bell bottoms from the 1970s. Flight attendants donned these and other retro uniforms on select flights through the month-long anniversary celebration and surprised travelers on designated days at the airline’s hub airports.

Alaska Airlines and its sister carrier, Horizon Air, serve 92 cities through an expansive network in Alaska, the lower 48 states, Canada and Mexico. This year Alaska Airlines celebrates its 75th anniversary, marking the airline’s growth from a single-aircraft operation in 1932 to one of the largest U.S. carriers.
