BLK already have plans to increase the runway length. when the issue first arose last year, now was the time when work was going to start(or plan to) but nothing as yet. The airport has hinted again about its plans to extend the rwy. When I do not know.
Also plans to either extend existing terminal or build a new one.
Ryanair already use 738s on the Stansted route which by the look of it always seems pretty full.
