At the risk of asking something I should know...
Doesn`t the B scale COS say thoust shall retire at age 55? And if so, doesn`t that mean that these guys extending are doing so on a new contract?
Also, when one gets bypass pay, aren`t you stuck on that (i.e. Yr1) till commencing your course. So lets say an S/O gets bypass pay starting today. But doesn`t start his/her course till Jan 01. Come profit share time, the said camper is now a J F/O, and renumerated accordingly, lets say two months salary for arguments sake. $80 k. If said camper had actually started their course at day 1, and jumped through all the hoops, kissed the right butts etc, they would be a F/O and would get an EXTRA $40k at p/share time.
Thats enough to pay for three and a half years parking at CX city!
