Really doubt that one, captainv.
DAL f/a's are usually offered a carrot every time they threaten to unionize, (e.g. Pan Am deal).

Most f/a's at the majors (the ones left/not furloughed) are topped-out on pay, and make substantially more than a topped-out regional f/o, (or some junior regional capt.'s).

So, these are the trends lately;
DAL can't seem to sell us, (even though we make them money),Comair's f/a's are getting DAL-style uniform upgrades,Soaper (a major impediment to Comair growth) is gone, our MEC is having "positive" talks with DAL MEC, DAL wants a 100-seater (DALPA only wants it if on their list) to compete with JetBlue & Republic, we have the E-jet already on the cert., and DAL is re-modeling/expanding JFK terminal to the tune of $1.2bil...oh, and JFK-based JetBlue entered a code-share with DAL's main rival in JFK (AA)...anybody else seeing a possible trend?
(I know, Spoilers, there are other indicators too...but these message boards are inherently rife with rumors and speculation).

Food for thought, eh?
