Okay, let them deny jetblue pilots and other non union carriers pilots jumpseats.
However, once that door is opened, then next it will be AMR boys denying UAL or LCC, since one, they are different unions and two, compared to AMR, they both have "lowered" the bar. Then the AAI pilots gets mad at DAL etc, etc.
It is a slippery slope, once you start down, well, it is hard to stop.
However, this topic, denying jetblue jumpseats, have surfaced a couple of times, as far as I know, other than a few ****ed off NWA pilots, it hasn't come to much. Looking at route maps etc, I really cannot see where the big competetion between jbu and NWA ocurs, but clearly the NWA pilots see it!
