LAX_LHR
Off the top of my head I've taken the IAD flight 5 or 6 times since it started, it's always been UA100 Eastbound and UA101 Westbound.
Glitch in the system???
On the JED....what are the proposed days of operation and the timings currently on view; just mentioned it to a friend last night who goes out there quite a bit and he was interested (if it's a non-stop that is).
