This ought to be really funny. In addition to carrying picket signs, are you guys going to also carry a stack of resumes to hand out to every UPS and FedEx pilot you see walk by?
The general public doesen't care about the cause of the regionals. Their only concern when they buy a ticket on Delta is "am I flying on Delta or one of those little planes painted up like Delta?"
What are you going to be picketing for, higher wages? Better work rules?
I hate to point out the obvious, but you have nobody to blame but yourselves. All those years of people willing to fly for peanuts, pay-for-training, and soon to be pay-for-fleet (i.e., Comair) just to walk through the terminal in a pilot's uniform fresh out of Riddle.
You crapped in your own playpen, now live with it.
