Agree with Pug. Plus--- there is plenty of room for terminal expansion at LBA. As usual money and minimising disruption while it's done will be the issues with that.
The way I see it, in the last five years the championship airports --- Bristol, EMA, Leeds, Liverpool, Soton, Newcastle not in any particular order-- have moved away from the next tier in the hierarchy. Not always at the same rate or for the same reasons or with the same business model but that's the way its gone. Obviously in Leeds's case the success of Jet 2 has been fundamental. Fourteen based, who would have thought it?
