Cancellation leg by leg... Yes.
Displacement rules... Not really sure but maybe someone getting displaced right now can clear that up.

Btw, as far as commutability (asked earlier) our 4 day trips are today commutable on one end. And our 5 day trips are almost always commutable on both ends depending where you're coming from. 4 and 5 days make up over half of all trips. Like was said, 5 days are rigged to 25 hours.
