I managed to get a few from
http://www.lhr-lgw.co.uk/
02OCT BA176 JFK-LHR > G-BYGD* (744)
05OCT B***8 LHR-FCO > G-BNWZ (763)
08OCT B***7 FCO-LHR > G-BUSF (320)
08OCT QF2 LHR-BKK-SYD > VH-OJT (744)
* - Not recorded but looking other dates it appears BA117 turns around in JFK as LHR on 02OCT G-BYGD operated BA117 to JFK. the day after G-BYGD operated a YVR flight out of LHR but with no record of it arriving so i'm 99% sure you flew on G-BYGD.
Why is A fifty-five censored out??
