You can now start collecting Singapore Airlines KrisFlyer Miles every time you spend abroad using your Currensea card. Currensea will convert your savings (vs. the main high-street banks) to miles every time you spend. If you select to allocate 100% of savings this will result in you collecting on average 2 miles for every £1 spent.
Before being able to collect Singapore Airlines KrisFlyer Miles, you must link your KrisFlyer account in the Currensea app by tapping your initials in the top left corner of your Currensea app, and going to "Contributions". From there, you can link your KrisFlyer account to your Currensea card using your KrisFlyer membership number, and then choosing what percentage of your savings you would like to allocate to KrisFlyer Miles.
