Clearly I meant airline loyalty, and not general loyalty cards. But I will stand corrected, I wasn't aware of the RBC offerings for BA and Cathy Pacific. The Alaska Air MBNA card disapeared from the MBNA site a few weeks ago. Its still listed on Alaskaair.com but the link no longer works.

So if you largely travel within North America, that leaves you Aeroplan or Capital One with Delta. On the chart you linked to, 50% of the airline cards are Aeroplan cards. If you take a look of the signup bonuses for the other cards, and compare that to the US variety and bonuses and you can see why most of us stick with Aeroplan just the same.
