If SkW does indeed have further growth with AirTran on par with what they have experienced in the past, then once again, upgrades will happen, movement will happen, shiny new jets will arrive, and any serious threat to OO of any union will be small.

I understand what you are saying. But don't forget that it seems like the NMB is going to change the rules on how airline union votes are conducted so I wouldn't count anything out.
