I can't see this going anywhere 😂
British Airways purchased BMI in 2012, wouldn't the airline have the legitimate rights for the use of the name of the airline if it was to be reused?
The same applies with British Caledonian Airways I should imagine.
If I was to resurrect a previous British airline it would be BUA British United Airways. BCAL British Caledonian Airways being my all time favourite airline. But I think BUA British United Airways is a great name for an airline especially if it had an updated version of the former BMI livery.
