Is the article from 1994? It contains the line "In 2007 the airport made the best of their sucky cipher and started promoting the airport with the slogan "FLY SUX.""
> This article was published in the journal of the Air Line Pilots Association, Air Line Pilot, in December of 1994. [...] I do keep this online version updated.
I think a more successful campaign would have been FLY GAY (GAY was one of the options they could have taken), but I suppose the code might outlast the novelty of the marketing campaign.
