Wow, crazy how the R space changes. I have pretty good flexibility - EWR-LHR anytime from June 24th to July 4th , saw ONE flight over last week - 2200 on 2nd July, by the time I had discussed with wife, it had gone !!!! So frustrating that you cannot search by R space as the priority and the dates secondary . I guess I just need to keep doing the seaches for a 10 day spread , every freaking hour, just to try and hit something !!!!
