which enrich miles credit card are you referring to?

If it's like HLB Mach Signature, no need to register, all transaction automatically converted to Enrich.

hong leong VI converts purchases automatically.

Take note that for HLVI / Mach Signature, all government payments like MBPJ,DBKL,MPSJ are not eligible, so is JOMPAY. TNB is eligible for miles if u pay directly to TNB not via jompay. I wasted a few months payment using jompay without getting miles...

For Mach VI, Signature, u need to provide to them your enrich account number when applying the card so that they can credit the points to you automatically. if not, you'll burn your points.

also there are limitation on points earning as per Kit615 said. Need to take note on the minor t&c.

Jtl, the surcharge for LHR is expensive due to the Passenger Departure Charge imposed by Heathrow for pax flying out of London. Alternatively, you can do a trip to Paris and fly out from CDG. much cheaper.

Asiamiles use a distance chart to calculate amount of points required. Use http://www.webflyer.com/travel/mileage_calculator/ to calculate the actual distance travelled by keying in all the transit point to get the exact range.

If I am not mistaken if u did not supply your enrich number, they will open a new enrich account for you and deposit your miles there. There is no "transfer" or whatsoever required as every RM2.8 you use become 1 enrich mile automatically.

Credit the airmiles to you (or the name of the credit card holder) then redeem tickets for anyone you like including your friends or colleagues.
