It's still quite amusing reading the thread.
Previous poster is correct that there is a very good reason why flight frequencies on most (if not all) former Flybe routes are much lower than they were back in 2019! It will be a very different marketplace where new Flybe is up against easyJet on EDI, GLA, AMS, Loganair on ABZ, INV and IOM, Blue Islands and Aurigny on JER & GCI, Emerald / EI Regional on BHD and so on.
I think the jury is out as to whether the Q400s will be any more reliable this time around and also whether the new CEO will prove more capable than those who went before. Yes, those individuals are gone but that does not automatically mean the new guy will be better. All of this has still to be proven.
Add into the mix that you have a venture capital backer which is allegedly already looking to sell the airline before it's even flown, salaries pitched at a level which aren't credible beyond the very short term, and it is certainly a volatile mix. My own view is that they're deluded, but that's never stopped anyone before in this industry!
