I don't understand why you think there is a need for extra stands, unless you know something I don't. Everything working fine this Summer season, if the rumours are true then next Summer will bring 1 extra based aircraft in the form of a BY/TOM 737. The new routes wont put much demand on apron space, the Jet2/ChanEx is already here all day every day, the AA757 is on the ground at off peak times and the RYR flights are only on the deck for 30mins. Therefore 1 extra 737 doesn't necicitate a apron extension, unless RYR decide to open a base (which i dont think is gonna heppen in the next couple of years). Granted an apron extension is in the master plan along with the terminal, but i think pax numbers will have to move on a milion or two before it happens.
