Cheapest flight I can get is around $500
Rob, have you checked flying into Houston or Dallas and then riding up with someone else? I'm not sure about airports in Austin, but I know Dallas and Houston serves as hubs for some airlines (and could potentially be cheaper). It'd end up making for a two hour drive after you land, but a New Year's Resolution means some sacrifice might be in order.
