lovetravellingoz - Could you elaborate what you mean by earn-to-burn ratio?
"earn-to-burn ratio" What it costs to aquire a point/ by the cost to redeem in points
Note one should also factor in:
*$ costs such as fuel taxes. Some programs like SQ's Krisflyer have similar fuel fines, whereas others such as somearab and USA based programs can have much lower fuel fines or none at all. When redeeming partner awards you can sometimes gain access to less fuel fines.
* Your time to aquire. For my some point earns are simply not worth my time such as some surveys as an example.
Earn:
You can earn at diffeerent rates. With credit cards their are all sorts of different earning rates subject to what is purchased ona range of cards. ie Hotels. Restaurants, Supermarkets. Buying Gift Cards can sometimes allow higher rates to be gained than if one bought at that business direct.
It is not just credit cards though. Different airlines allow different earn rates of points for flights, and their are all sorts of different bonii for purchasing different things.
ie number of programs have online malls that earn points. Some with the same shops. Earn rates can be different, and sometimes short term short term bossting (ie say doubling) can mean that one program may be better than another.
Burn:
The same redemption can have different costs in points and fuel fines/ airline fees with different programs. (ie not all programs are equal)
ie Redeem a partner award with SQ on VA for MEL-NS and it is 11K in points and no $ costs. Redeem direct with VA and point cost is much higher and you also have to pay $ in fees.
One FF program is not always necessari;y better than another. Particular routes may be better on one and not another due to how the system is run and award tables structured. Some are region based. Some are distance based. Region based ones often have anomolies due to how the regions are constructed.
By watching all the various earns and burns one can improve ones overall earn/burn ratio.
Add to this things like credit card tranfers bonus specials, or redeeming etc to further improve ones average.
By being in multiple programs with multiple earning opportunities such as different credit cards one can significantly improve ones overall earn to burn.
