Destination Adelaide

We are not looking to travel until next year, but the prices are staggering !! We went a few years ago, I'd just had a redundancy payment so treated ourselves to business class with Qatar which was superb, but the cost was 6K (3K each). Now I'm finding that economy is about 1.5K, Prem ecoonmy 3.5k and business class is totally out of my league now.

Anyone had or having the same dilemma ?

Any tips ?
