Of course you are free to exercise your choice, but if everyone follows your example there is a risk ASW will disappear altogether, leaving Cornwall with a useless summer-only service (which, you can bet, will cost a darn site more than £60 return) to a single destination.
You will find that Flybe is one of the least reliable airlines in the sky (or, more accurately, on the ground). It does not give a stuff about NQY or Cornwall beyond trying to find itself monopoly routes on which it can gouge passengers with outrageous fares.
Enjoy your flight!
