should it be possible to book flights from australia to europe on JAL then? or only aus to japan

DoubleplatinumIf youre gonna spend 165 AUD to get into the lounge just to drink... you would probably get much better value just sat at a bar in the airportThe price is definitely not worth it but that's fine... it will only appeal to those sad people who can't handle being in an airport without ...

but Dubai terminals have free shower rooms...Then you can just go to a restaurant and pay for whatever meal you want... have some champagne... and still probably spend less than $100

Dumb question... but Is this flight daily?

If you have mid tier status you get lounge access anyway. Or there is priority passExtra luggage can be useful yeah, especially on a big trip like a honeymoon... but even if you just paid for the extra luggage, you'd still save money/points
