The FSB system is unacceptable.
There needs to be add pay associated with it if they don't fly you.
Driving to the airport to sit for four hours for no pay is UNSAT.
depending on where you live you could end up four hours on the road, plus four hours at the airport for an 8 hour day for no pay. seriously.....this AFU.
If they fly you, you'll at least get a five hour minimum associated to your line value. That's something. I would say 2 hours of add pay is fair for the pilot if they don't fly you.
