When Flybe increased their BRS presence a couple of years ago (no base but five daily summer routes) it was confidently stated by the local press and hinted at by Flybe that within a couple of years there would be at least fifteen routes out of the airport (ie by now).
Hasn't happened although perhaps the reason might be the incredible success of most of their routes out of EXT which I suspect has surprised many. It has me although I'm not an aviation professional.
For example CAA provisional stats for May show an average load on the ALC (5 rotations per week) of 135, for AGP (4 a week) 132, for FAO ((3 a week) 119 and for PMI ( 2 a week) 105. These routes are of course operated by the temporarily-leased B 733s.
The Embraer 195 won't carry as many as the average for the first two destinations and would be tight for the FAO. A nice little problem for Flybe to contemplate. Doubtless the AGP and ALC would go daily in the summer on a smaller a/c.
