Oh! There is another DH anomaly as well! On the PEK/NGO route, by the time you come back you are acclimatised and therefore can operate back as 2 crew. Of course EY send a second FO and he/she has min rest in PEK and then becomes then, ironically, reason for having a third pilot as he/she is NOT acclimatised!! If he/she were not there then we could do it anyway!
Standing by to be corrected!
