I'm definitely not trying to stir the pot here, but my response would have to be no. Why? My rational is simply this. The FA's at Delta have already voiced their support (minority), or lack of (majority), of becoming a unionized organization. My support by wearing an AFA pin, or anything for that matter, would go against the MAJORITY of FA's who have already voted on several occasions not to become members of AFA. I'll support the FA's as a whole, but you'll have to decide this one, again, on your own IMHO.
