Finding upgrade seats
sbm12 - great job and very well detailed search solution that everyone seem to appreciate.
However, I am too lazy to click on each result's 'Fare Class' link and review each box's fare codes, especially when the result yields lots of flights. I am still sticking to the other method you showed me a while back - click on the Advanced link and selecting MileagePlus Upgrade Award box. Easy to see which flights are upgradable as it is indicated in red so I just skip over those flights.
