Then, figure out if you can accumulate the require miles effectively or quick enough. Use awardace.com to compare whether it is cheaper to accumulate other frequent flyer points/miles to fly the same route in First Class. e.g. it may require you 200k Q miles to fly A to B but it just require 100k Qantas pts to fly the same route. You only have 10k Q miles in your account but you could earn Qantas pts twice as fast as Q miles. I would then focus on collecting Qantas pts.
