Interesting to think this FlyBe Mk2 reckon they'll be back this year.
A "summer restart" with current social restrictions in place and all four nations of the UK unable to agree any commonality with said restrictions is going to seriously limit any launch plans for a "new" airline. Particularly since most people will have already booked accommodation wherever they plan on holidaying domestically, most will plan on driving due to it being easier having the car.
Also, business travel will never be the same again with the large scale adaption of zoom meetings and the likes. Let's not forget that FlyBe 1.0 had a large proportion of business travelers on their first and last wave flights. My partner for instance used to take two trips per month minimum and will no longer be doing so in a WFH environment.
With SAGE now worrying about local restrictions due to the SA variant etc who knows what farcical restrictions we can expect to rear their ugly head.
Take it from someone who is currently flying that this summer is all but a write off- as for next winter god help us.
I did a positioning flight into BHX lately on an our A320 arriving at about 2000 and the terminal duty manager had to come and turn the lights on and unlock the terminal to let us out. The passenger numbers are that bleak. Terminals lie empty, public perception is anti-flying due to being anti-variant.
Good luck and all but the industry has fundamentally shifted and those who have been away from flying for over a year potentially haven't seen first hand the empty terminals and airport car parks- or received a load-sheet in single figures on an aircraft and route which used to be triple figures.
