Thanks for all the responses!
I agree that you should stay in CASS as it is a program which is used to verify your credentials. There would obviously be priority given as a courtesy to guys flying to work over guys flying home over guys flying for pleasure as there always is!
The company does stupid things though because they see us as flying for "Free" ... they dont view this as our last resort (which it is most times!).
Anyway, I will keep you updated on whether or not my airline removes me.
I believe that I should still be able to sit in the back even if I'm not in CASS - I will probably have to stuggle with the gate agents for that one tho!
