Unless Cardiff attracts a based airline I'd say Scotland is off the list for now as loganair have made it pretty clear that they are not interested. Aer lingus should be the target for the return of the Irish routes and Air France HOP! for Paris. The other priority needs to be keeping TUI at 3 based aircraft for S21 and getting Ryanair to expand again.
As for cargo they need to invest in a cold store.
