I agree that adding a class of service filter to the search would help.

Also, sometimes it listed one way and return for the same airline. I think if the program allows one way only list one way and not return. However, if you must do round trip, then list return only.

What I did to get around most of the issues people had was to copy and paste into excel. I could then do everything I needed.

I agree this is very valuable in finding the sweet spot.
