maybe it's time to court the transit traffic from Prestwick as they seem to be in disarray?
Can't see this being big business for Prestwick these days if you exclude the military then isn't Prestwick becoming redundant, with such business now being spread more randomly dependent on range of individual aircraft. You certainly wouldn't attract very small aircraft which would in most cases be looking to put down as soon as landfall when eastbound & westbound would wish to depart as far west as possible to maximise their options on limited range.
