Well, this might be different, but I was jumpseating AFTER being diverted to another base on my last leg. Company would not positive space me home from there, only to my base so I jumpseated from there home ( this was CAL ). The flight was WIDE open ( 35 PAX ) on a 73 with 4 in 1st class. The FA put me in 1st and as we were pushing back, 2 FA'scame to me and said the CA said " if he wants to sit in 1st class, he can pay for it!! " come to find out, hes a scab, NO SCABS in my jumps seat if I have anything to say about it!!!!!!!!!!
