I have travelled JQ Business a number of times and would rate the value for money highly - especially if you are not chasing status credits. Although even with Max Bundle it can still represents good value - depending on how you intend to use your status credits. The worst seat is the middle seat in centre row - so avoid that seat. The Cairns - Osaka Flight with JQ Business is a good flight - I have found service cheerful and friendly and plenty of drinks available on request.
