Over the road from BA we at Virgin operate 3 man LHR-HKG. At least we do in the british winter{gmt versus bst}, and always 3 down to SYD. Like BA we change from 3 to 4 for half the year as FTL 'S become more limiting. Unlike my dark days with the silk PJ brigade we divide rest in a more gentlemanly fashion. ie, a 12 hour flt would have the extra pilot in bed for the first 2 and a half hours or so, followed by the PNF in bed for about 3 and a half, followed by the PF, and the extra in bed for the last 2 hours or so.
Do i miss the Tristar? Yep.
