Think for a minute and tell me what value would CV or AAI see in BlueBird? Contracts? You can get them anyway. AOC? Why they would need it? Traffic rights? There are none. And no LHR slots either. No its own network. And nobody is interested about 733 and 734 freighters any longer - you can get them any day.
They are nice airline but there is little to no value in buying them for heavy metal players. Standalone investor? Maybe.
