Based in the state of San Andreas circa 1992, Juank Air is depicted in game to provide air travel between airports in Los Santos, San Fierro and Las Venturas, via the Los Santos International Airport, the Easter Bay Airport and the Las Venturas Airport, respectively. Its logo company can be seen on a ticket purchasing interface when buying plane tickets, and its name is visible on Nevada propeller planes. Juank Air's may have also offered trips between Liberty City and San Andreas, as Carl Johnson is seen registering his flight from Liberty City via a Juank Air counter.
The name of the airline is a play on the word "wanker" (slang for someone who masturbates) and is emphasized further by featuring a fist on one of its logos. The name of the airline could also be a play on the word "junk", which is a slang term for genitals.
