yvr_amm

So, was SE for 5 years prior to going on a work hiatus for 18mths. Unfortunately, heading back to business travel now and am trying to decide on which program to join now that I'm free to choose.

Travel will be mostly NAM out of YVR. Half J and half Economy. I expect to fly between 50K to 75K, I don't expect to fly enough to hit 100K. As I really don't see much value from AC unless SE I'm pretty interested in other options. Looking at United or even Westjet.

Suggestions?
Any success with status challenges in this scenario?

thanks!
