The reason for that clause is the simple fact that part of the agreement between Delta and Pinnacle states that Delta will have the ability to change our total block hours from month to month. Capping the lines to 75 means that either a) there will be a while lot of reserves on a given month out b) there will be no reserves for that given month... Since our guarantee its 75 hours why would the company want some people to have the ability to break guarantee when they can almost do away with pilots going over guarantee... Does that make sense? Typing on my phone doesn't help my thought process...
