I've managed to do the DTW to LHR route on BA in less than 6 hours with a scheduled flight time of 7hrs20mins. It also involved 100mph+ tailwinds and severe turbulence that was so bad the dinner service took twice the usual time after being put away and restarted twice. Unfortunately we ended up holding over LHR until the airport opened at 6am.

Is it possible BA pilots sit in the strongest tailwinds to get best possible fuel saving? I've never experienced it on any other airline.
