I am thinking about 10 years or more into the future. I doubt that by then the Q400 is still in production (Bombardier has already offloaded it to Viking, IIRC). Maybe the ATR72 will survive, but for SOU leisure routes it is no option. The E75-E2 is a dying species as well and, if you ask me, only around because of US scope clauses. If Flybe is alive and kicking around in 10 years time, they will have moved on to something bigger than 80-100 seaters. Particularly now with Virgin/Stobart running the show.
