I suspect the reality at least for the first year or so is that yield will go out the window and Flybe will use the only tool they have, which is price.
So the real question will be how much debt Cyrus are prepared to run up in the hope that they can get a monopoly on routes and recover the yield. This at least will give them a chance of flogging it for a profit.
The second question is how much debt their competitors are willing to run up to stop them.
As has been said before, the problem with high frequency 70-80 seater Ops is at some point the LoCos get interested.
Rogue One, no problem old chap, it’s all smoke and mirrors anyway, both fuel burn and number of sectors you can wring out of an airframe in a day. Depends on a million and one factors.
