To have 15 days OFF is not happening for the vast majority of pilots, left or right seat.
To put it simpler senior pilots get what they want especially 15+ days off, no night flights, and very few SBys.
All the others get minimum days off, night flights and double sectors, irrespective what they bid for.
So there are privileged pilots and non privileged pilots. Is PBS doing what is supposed to? Is PBS meant to give someone 8 or 9 days off MORE than his/her colleagues? We were told that it was meant to control our life style, however PBS DISCRIMINATES, rather than trying to keep some degree of fairness.
