White Owl...
The TSA pilots tried to start a jumpseat war against gojet pilots last year. You know what happened... the company (who incidentally owns the jumpseat) banned everybody from using the jumpseat.
There are black lists out there... those are of people who crossed a picket line which has absolutely nothing to do with going to work for the competition. They are not the same thing. These companies are competing against mine also but there is nothing "professional" about your reaction.
