Until we see the actual contract (TA) language, if it exists in the next TA, nobody knows the details on how this would work, and even then, there will be unforeseen loopholes which will be exploited by the company just as there always are.

Bottom line, the only reason the company wants Virtual Bases is to eliminate DH credit. That is a 3 way win for them. It saves them paying the DH credit, and the seats can now be sold to customers rather than held for crew, it saves them on body count in every category where the DH credit is eliminated, and it saves them the cost of hotel rooms for the DH crews.

What the pilots get is.... they get to drive to work instead of a guaranteed PS seat to/from work, but the trips will be worth less overall due to the reduced DH time, so those same pilots will have to work MORE to accumulate the same monthly pay/credit time. Meanwhile, they will stagnate in position longer as there will be reduced need for pilots in the categories above them, as that DH credit time goes away too.
