I was introduced to the AA I-dine program by my brother. I promptly signed up and have earned plenty of miles. It was only afterwards that I found out that pretty well all US airlines (and Priority Club) offer the same program.

I have told many people about i-dine and I am frequently asked "which is the best program". So for other Canadians like myself who aren't partial to any american airline (Air Canada does not participate), which program is the most lucrative? I understand that different bonus apply at different times, but if you wanted to focus on one program, which one would it be?

Based on my limited experience, it seems that AA offers great bonuses, but I want to see if others agree.

TIA
