If you are not too concerned with hotel loyalty programs and you simply want to earn the most miles on hotel stays, Kaligo is truly the way to go (so long the price difference between Kaligo and a bigger OTA is not too drastic) to chalk up those valuable miles. If you are based in Singapore and have been put off by the upcoming KrisFlyer Miles devaluation, Alaska Airlines Mileage Plan miles are something worth looking into.
Between 01 March 2017 to 31 July 2017, earn up to 6 miles per S$1 of retail spend charged to your DBS Altitude Visa Signature Card - you do have to register for this promotion so make sure you do that before you make any eligible spend. DBS markets it as 6 miles per dollar but you essentially only earn that rate between S$2,501 to S$5,000 of the total spend on your card. The first S$2,500 still earns a maximum rate of 3 miles per dollar. If you do charge S$5,000 worth of eligible spending to your DBS Altitude Visa Signature Card, you will essentially earn 22,500 miles (equivalent to 4.5 miles per dollar).
If you are charging S$5,000 on Kaligo, you can potentially walk away with a grand total of 57,500 miles (in the form of DBS Points) which is enough for a return-trip from Singapore to Hong Kong on Business class (check out what a Business class flight on Singapore Airlines from HKG to SIN looks like HERE!) remember the flight booking needs to be ticketed before 23 March 2017.
I am not saying that Kaligo has the best prices on the internet but if you are looking for a quick way to amp up your miles, I do not know of any other method in Singapore that gives you 11.5 Miles per S$1. Give it a try and check out the prices - what do you have to lose?
