If you are a member of the Aeroplan frequent flier loyalty reward program and fill up the tank of your vehicle with fuel from any of the greater than 1,800 Esso service stations in Canada, you are in luck: during the Double Miles Event through May 27, 2013, you can earn double the Aeroplan miles you usually earn as follows:
Esso Regular Earn two miles instead of the usual one mile per $3.00 spent
Esso Extra Earn four miles instead of the usual two miles per $3.00 spent
Esso Supreme Earn six miles instead of the usual three miles per $3.00 spent
A minimum purchase of three dollars is required to earn Aeroplan frequent flier loyalty reward program miles at Esso service stations. Aeroplan frequent flier loyalty reward program miles are earned by swiping either your Aeroplan card or swiping your Speedpass linked to Aeroplan at the fuel pump or in the store when you make a purchase.
FlyerTalk members are hardly excited about this promotion. For example — as a result of calculations using differential analysis — FlyerTalk member brunesconcluded that even with the current promotion, the value at filling up the fuel tank of your vehicle is greater at a different petrol station than it is at Esso.
I cannot comment on that specifically, but I can tell you that I regularly perform a differential analysis with my credit cards with regard to filling up the tank of my vehicle with fuel, taking into account the following factors:
How much fuel my vehicle needs
The difference in price per gallon of fuel
The benefits I earn from which credit card I use
For example, let us say that Fuel Station A charges $4.00 per gallon, while Fuel Station B charges $3.90 per gallon, and let us say that my vehicle needs 20 gallons of fuel. Credit Card A is affiliated with Fuel Station A, giving me five percent cash back on my purchase. Credit Card B is a general credit card on which I earn two percent cash back on my purchase.
With Fuel Station A — at $4.00 per gallon for 20 gallons of fuel — my purchase will be $80.00 total. With a rebate of five percent of the $80.00 by using Credit Card A, I earn four dollars. Subtract the four dollars, and my purchase cost me a total of $76.00.
With Fuel Station B — at $3.90 per gallon for 20 gallons of fuel — my purchase will be $78.00 total. With a rebate of two percent of the $78.00 by using Credit Card B, I earn $1.56. Subtract $1.56, and my purchase cost me a total of $76.44.
In this case, it is actually less expensive for me to use Fuel Station A even though the price per gallon is ten cents more expensive than Fuel Station B when I use the appropriate credit card.
The usefulness of this promotion depends on how much you value each Aeroplan frequent flier loyalty reward program mile. If it is not too much trouble for you, perform a differential analysis to calculate whether or not this promotion is right for you.
However, if you need the Aeroplan frequent flier loyalty reward program miles — to top off your account in order to have enough of them to redeem for an award ticket, let’s say — then forget the differential analysis and go for it.
