Guys, is it feasible at all to maintain ST status with an AU base? I've got a QF gold, working towards plat, but the redemption rates are really poor and upgrades are difficult with miles and am looking to switch. I am aware that DL has a JV with VA, but I don't do a lot of prem flying domestically due to really high prices (e.g. >$2000 return on a 500 nm sector).
