If you want to fly on a jet rather than a prop then that option is available, as is the arrival onto a contact/jetbridge stand rather than a remote stand where you're bussed to the terminal. You just need to fly BA instead of Flybe.
I guess it depends on the compromises you're willing to make. For a day return on a Monday, BA want £441, Flybe want £187. At least there's now the choice I guess but it's very early days.
There are probably enough price sensitive business and leisure customers to ensure success for Flybe, and the significant number of codeshares they have, coupled with smaller aircraft means that they can probably charge some fairly good prorates to their codeshare partners rather than giving these seats away below cost due to excessive capacity.
I wish them the best of luck.
