Hello. I am new to Australia (and to this forum!), having only moved here three months ago from the UK. I'm based in MEL and expect to be flying internationally at least a half dozen times over the next year to the US and Europe. I hope to use these flights to begin earning miles towards a family trip back to the US, and I'm trying to decide whether it will be best to do that with Qantas or American's miles program. I already have some AA miles and AA seems to have the better rewards levels for flights to the US from Oz, but AA has also just changed the levels at which they award miles and status on Qantas flights, making it more difficult to get 100% of the miles flown. My travel is for work, so I'll have some flexibility over the fare class I go with, but probably not much, since I'll have to go with something near the cheapest option. Is there any general advice about which of these would be the better option for racking up miles to use for reward tickets to the US from MEL? Thanks!
