Wow! Awesome tip. If I am reading this correctly, then I should be able to reach the Platinum challenge if they offer it to me.

I think my math is correct:

985 miles per leg.
July 1st - October 1st = ~13 weeks x 2 legs per week = 26
26 X 985 = 25610 points since most fares I buy earn at 1.0 per mile.
I may even get some Y, B and F fares booked since it is a busy route. i will also book more 1 stops so that I get some more points.

Does that look right? Should I go for it?

BTW...thank you for the tip on CO. I hear they are a great airline, but if it is difficult to get upgrades, then that will steer me away.
