A couple of other things....

Redemption flights seem to be available - if you ask enough agents! - if Go flights are available on the DJ website. Connecting flights excepted, we never did get a positive response on those.

There seems to be some confusion about luggage allowances as some of the tickets say 20kg and some 23kg. Bit of a pain as we're arriving in Sydney on Thai in F and will have some relatively heavy motorcycle gear with us. Might actually be best to post that from Sydney to Adelaide - does anyone have any tips to help with that?
