Training Pay is $600 dollars per week. That will change to Flight pay status when you begin OE. Figure on about two months at $600 per week. Lodging during training... Strictly by the contract it will not be provided until completion of initial GS... thats indoc and the first week.. so figure two weeks. Its very well possible though they are paying for all lodging...HOWEVER..as stated the CBA says not until completion of initial GS. Same goes for Per Diem. (I will make some inquiries today and report back on this).
For JHUGZ... probably the only things I would study early is IF they send you a company manual disk... Look through the Limitations and required memory items. Anything else is probably spinning your wheels until you have some context. IF they DONT send you a disk.. I would refrain from using study materials that aren't from K4 at least initially.
