Still reckon a flexi with discount code and 9000 points is the best option. Full flexi SC's as well as additional point earn for extra dollars (so 5k or so for a flexi if you're a WP).
Short of aspirational awards such as EY F (which i've just cashed in for), the 5k points earned and supplementary points from CC's and the like mean I travel to and from PER for $500-550 and 9k points, each way, every time (and then get 4 freebies with WP each year where the 10k points each trip give me 4 sectors upgraded when the complimentraies are done for the year).
