While FAA identifiers for airports aren’t technically acronyms, the three-letter codes can give rise to their own headaches. Just ask the Sioux City Gateway Airport, which the FAA saddled with the unfortunate designator “SUX.” Airport authorities petitioned for a new code, and the FAA – and this is not a joke – offered them “GAY” as a nod to the “Gateway” part of the airport’s name.
