Never mind the runway extention, they will need to extend the ramp to fit all these aircraft in.
However I did notice that the bucket and spade routes are not due to start until summer 2012, perhaps Flybe are planning a fleet reduction at Belfast before then?
There is space to park a few more aircraft on the GA apron, however the airport dont yet have enough equipment to bus a few 737/Dash8/Emb load of PAX there on a regular basis.
