I've been a collector of Airmiles for the past 13 years with two BMO Mastercard. I pay the $99 fee on both cards to get $15/1mile.

Within the past 3 years however, I been traveling a lot (on AirCanada+Star Alliance), and this year I've finally hit Elite 35k with Aeroplan. Last year my wife and I were both Prestige and with our flying we managed to get upgraded several times to executive class (even without using points while flying Ethiopian Airlines).

Lately I've been contemplating if I should be collecting Aeroplan compared to Airmiles with my credit card.

While looking up some travel rewards with airmiles, I looked up a normal trip for us from YVR-YYZ return. I decided to look this up on Aeroplan. Both are the same dates, the only difference is the AM is direct flights whereas the AE has one stop. But the price difference was significant.
Airmiles = $235.73 + 2344am
Aeroplan = $143.89 + 25000ae

I looked at the breakdown of the charges:

Airmiles
Redemption Admin Fee $15
HST $25.48
Airport Improvement Fee $45
Canada Air Security Charge $14.25
Security/Fuel Charges $136

Aeroplan
HST $15.64
Airport Improvement Fee $30
Canada Air Security Charge $14.25
Fuel Surcharge $54
Nav Canada $30

Seems like Airmiles joins the Nav Canada and Fuel Surcharge together, but it seems awfully high compared to Aeroplan. So I decided to check one more thing. I checked the same Airmiles flight, on Westjet's website.

I picked the cheapest flight options, and the breakdown of fees are?:

HST $65.44 (based on the $438 flight)
Airport Improvement Fee $45
Canada Air Security Charge $14.25
Other air transportation charges $46

So that last field should be the Security/Fuel Charges from Airmiles. But it's a difference of $90.

Is Airmiles hosing me?! Looks to it. I still need to look into this more, but right now, I'm seriously contemplating cancelling my Airmiles cards and moving to something else. I have close to 10000 Airmiles at the moment and can't help to feel that I should of looked into this much earlier on.
