So CX270 (3 July 2011) operated AMS-HKG with only 3 crew.
"Roster disruption" was no doubt used as a lie to
cover up the fact that one of the originally assigned FO's was pulled off to crew another flight that was short.
Always thought that the proviso in Ops Manual for 3 crew back to HKG was reserved for sickness in the outport.
Another clear violation and blatant abuse of procedures in what these
will do in their quest to save a dollar.
