Whilst TF may indeed not be the easiest to deal with he at least knows his subject - operating a LCC.
ANA only know one thing - how to operate a bloated, overstaffed, micromanaged, state subsidised bureaucratic monolith.
It beggars belief that TF would allow management control to be vested in ANA - but probably what he had to do to get in to the Japanese market - and he'/AirAsia have been bitten big time.
All ANA could bring was "that's how we've always done it" and when any disputes may have arisen no doubt used the time honoured Japanese way to resolve any issue:
"...I'm older than you, I'm Japanese - so f**k off...."
of course delivered in more polite language and accompanied by a slight bow - which then makes it all OK!
When/if an account is ever written of the JAL invasion, if honest, it will recall how ALL the smaller carriers were adversely affected whether in operating costs, standards, variation from established airline and manufacturer SOP's, operational environment and other aspects.
I have no doubt ANA brought a similar "skill" set to AirAsia Japan.
