I think it would be a great shame if jet 2 chose not to expand at Edinburgh just because monarch are planning to offer scheduled flights out of there, surely theres room for two airlines?
As said before, monarch do tend to be a slightly more expensive so i am sure jet 2 would appeal to folks on a tighter budget,further i was chatting to a bod at work about who is a bit of a spotter and he reckons monarch just havent got enough aircraft to operate a big service up there ,how true that is i dont know
