Reroute off of your original rotation and reroute outside your trip window are two different things now as well. The pay treatment now stacks with each other.

Let's say you get rerouted on just your last day (with all the restrictions that go with that), you're making 150%. If they also take you outside your original release by 4 hours or more (non-ocean crossing), you're going to get an extra 100% for the entire last duty period. If they take you into the next day, that's two duty periods with 100% premium. So, essentially 100% for what you do, 50% for the non-original legs, and an extra 100% for the last duty period(s).

250% pay on the days you get in late and fly an extra day. Release after midnight for bonus points. If you happen to be on a green slip....well, you get the idea.
