The challenge for SOU really is what will happen if one day Flybe grows out of its Q400 operations - most airlines over the decades move from smaller to larger aircraft..Should BE one day move to 120-150 seaters, something needs to be done to keep SO competitive. I can think of quite a few airports on the continent with 1.200m'ish runways that have lost airline service as a result of the disappearance of 30-50 seater turboprops.Airports with 1.500-1.700m runways will face similar problems once airlines move away from 80-100 seat aircraft.
