Hands were sort of tied as the 110 odd A320/1 existing order couldn’t be reduced or changed, unless the company wanted to increase its order. Jetstar Japan, Singapore, now dead Vietnam, originally was going to source from this 2011 order. That changed a few years ago to now not. Gives them the flexibility to also change delivery dates now.
Not great for Boeing and whatever follows the MAX next decade.
Will be a large pay gap between the Star and Mainline on the bus though, especially as one of those groups works more.
