Cathay Pacific are offering double Asia Miles on Economy Class flights from Australia to Hong Kong or Mainland China booked before 15 September 2017, for travel until 31 October 2017. An additional 1,000 Asia Miles are on offer if you book via the Cathay Pacific website.
To get the bonus points, simply register on the Asia Miles website and then head to the Cathay Pacific site to make your booking.
If you’re considering travelling to Asia or beyond, I highly recommend Cathay Pacific. I recently travelled on the airline’s new A350 aircraft from Brisbane to Hong Kong (and onwards to Europe) and found the aircraft, leg room and lounges to be excellent. The service was comparable to their competitors; not outstanding but good.
