Re: Australian Aviation Thread - June 2020

I’m still trying to understand why QF are running their A330-300s on cargo only runs to China and Tokyo as opposed to the 787s. I get that the -300 is preferred over the -200 because its belly has more volume. Furthermore I get that the fuel burn advantage of running a 787 on transcon cargo flights...

Another thing that may hamper early frames longevity is if they still have early CFMI -5A or IAE A1 engines on them. Parts for these may be running low globally and any aircraft now being scrapped that have life on internal engine parts may even be going up in value to support what remains in service.
