It would be nice if the greasemonkey script expanded these Fare Class blocks as well... maybe this is finally the excuse to dig into javascript.

I did look at both the original confirmed segments as well as the waitlisted ones - none have the link anymore. Previously, all 5 confirmed segments on UA metal had the link. If it makes a difference - CVG - ORD - (NH metal) NRT - BKK - NRT - EWR - CVG. All original segments appear to be identical otherwise to before, with waitlisted at the bottom.
