I've got one issue and a feature request, and must admit I haven't read through 443 pages to see if others have mentioned them.

1. When displaying fares for AC flights, I do not see the Y, B, M, U booking classes. The results show all the lower fare classes, and then the premium economy and business classes. As far as I can see, Fares/PSH is the only option for displaying fares.

2. Feature request - monitor availability of a specific class on a specific flight and send notice when the class becomes available. For instance, this could be R class for upgrade availability on AC. I have read elsewhere on FT that ExpertFlyer offers this feature.
