Phew!!!!!!
I wondered if I was going color blind also. I tried to book PHL-LGW and PHL-AMS anytime in Sep with the nice colors that it showed. Unfortunately the best I could book was one way in B/F (50k) and a SleazyPass(tm) (another 50k) for the return. I then noticed the "elite login may give better results." So I logged in my Platinum stuff. A few more + colors came up but nil nice stuff.
I then tried EWR-LGW, EWR-BRU and EWR-AMS as I thought going via a hub would be easier. It was slightly better but it added mainly 1 (CLE) and 2 (MAN) connection flights totalling 12+ hours in route.
Its the old Continental Smoke-n-Mirrors(tm) crap again folks. I then called the so-called elite line but wore out after 30 min of (A) "What dates do you want me to try?" and (B) "Sorry no standard B/F availability for those dates".
