That's going to make reserve manning and IROPs recovery kinda "different" isn't it? Delta is more careful about Whitlow and crew rest than other airlines I've flown for (which is nice).
ER short call is tough on commuters.
With the 767 going to every continent except Antartica, them's going to be some giant sized Jepps for a reserve pilot who can't be sure where he's going.
A ship set, or better yet, electronic versions, would be nice.
