Why not? Do you see JB emulating a SWAPA model? If so, didn't that recieve a fair amount of support by SWA itself? From what little I know about D & D, I doubt that a JB pilots will benefit from the same type of support. A stand alone union could take quite a long time to stand up whereas ALPA could be on property in a heartbeat.

Greedy, the D & D I refer to above are JB executives, not your favorite role playing game!
