From now until the end of 31 December 2018, earn double Hilton Honors Points for all eligible stays at participating Hilton properties in Asia Pacific that have been booked and consumed during the aforementioned periods. This offer is only valid when you book direct and pay with a Visa Infinite or Visa Signature card only. If your card was issued in Australia, China and Japan, a regular Visa Platinum Card will suffice.
The double Hilton Honors Points will only applied on top of your base earning - this means to say that you can earn up to 20 Hilton Honors Points per USD 1 spent at participating properties. If you are based in Singapore, the best credit card to use is probably the DBS Altitude Card which gives you up to 3 miles per dollar (up to S$5,000 each month) on all eligible online travel spend but you will have to book a prepaid rate. Hilton is also currently offering triple Hilton Honors Points for all eligible stays in Conrad and Waldorf Astoria properties (double points for everything else) from 10 September 2018 to 03 January 2019. If you have not registered for that, make sure you do since these two promotions will most likely stack.
Even if you do not have any status in the Hilton Honors program, you can easily earn 30 or 40 Hilton Honors Points per USD but if you are holding top-tier Diamond Status, you are looking at up to 50 Hilton Honors Points per USD with these two promotions - this does not include points or miles that you earn on your credit card! If you have signed up for the Miles&More 25th Anniversary promotion, you will very likely receive 2,500 miles for each consumed stay between now until the end of 31 October 2018 so you should definitely try to fit those stays in as soon as possible.
