I haven't noticed legacy wings in a while. I do still notice slick ties and cowboy boots in IAH and unbuttoned blazer, no hat and a backpack draped over the shoulder of guys in SFO and IAD. Having said that I have noticed most guys seem to be wearing the uniform correctly (blazer buttoned/hat) this year. I do think it is tacky to be mismatched (one guy wearing the leather while the other wears the blazer) but it is approved.
