I am arranging some hotels for my europe trip and I just realised that it is possible to triple dip but not sure yet and this is where I need guidance to whoever has done it before..

1. I will book through booking.com via A3 website which will get me Aegean miles; 1€ is to 2 award miles

2. Use my Visa card to pay which ties up to my Qantas Frequent Flyer; $1 is to 0.75 miles

3. Earn rewards upon check-in by quoting Krisflyer for non-airline partner of SQ (i.e., Hilton, Accor or ICG). I might get 500 KF per stay one certain hotels.

If there is no thread yet, can we discuss to maximise miles run on hotel bookings.
