I agree with ung1 on the mileage accelerator. Barely any extra on the SIN routes. Another thing I am quite p1ssed about is that there seem to be no upgrades available on my usual route (LON-DXB-SIN) over the next six months. I tried to upgrade three bookings (for the next 4 months) however no upgrade available for any single one of them. I keep asking them when the upgrades will be released and nobody at Skywards seems to know. They could give me a billion miles for my birthday, if I can not use them due to non-availability of upgrades they are worthless! (J and F still wide open for my dates without upgrades by the way).
