And just to clarify, you get paid on the 1000 stick+bunk limit not just the stick time?
That's how it is today. We get paid for any hour spent in an airplane.
But the main constant here is change - for the worse. Credit (pay) hours include dead-heading and bunk time however this has not always been the case and will one day change again as the need for ever-tightening belts continues to assert itself.
For the time being though, the *****s running things here are restricted by their main phobia of paying us a single cent more than is necessary. Since credit hours include everything, the goal is to ensure no one does more than approx *90 hours per month in an airplane in any seat or even the bunk. This won't last long.
*90 - ie the monthly limit which is worked out to the 5th decimal place, depending on the number of days in that month.
