Or, the airlines could create a system that would allow us to actually reserve the jumpseat, similar to FedEx. First come, first serve. When you get your line awarded for the next month, you just have to go and reserve the jumpseat for your flights to and from home for the whole next month.
There could be a stipulation or two to prevent abuse. For example, be required to register a home airport, and only have the ability to reserve the jumpseat between your home airport and wherever you're based.
Something like that. Just throwing ideas around.
