Thank you all for your input...I may try a DTW mini run, depending on the YXU-DTW fares...that way I won't get stuck in a big line-up crossing the border by land!

As for my incentive to get P, because of a variety of reasons, my office pays for full-fare economy...which means those u/g certs will come in fairly handy! Although P gets 2 SWU and 4 NA only, I've only got three work trips scheduled, two within Canada (using those 4 NAs) and one either to Asia or to Europe, which will make those SWUs pretty handy...I know I won't get MLL access which stinks, but I might just pony up for the MLL membership (although with only 3 biz trips, it may not be worth it!)

Thanks all for your input, it's good to know that there are great resources like FT out there!
