I am talking to an agency in China and the confirm exactly what Joe falchetto 64 is saying
Actually Sichuan Airlines has requested to employ foreign captains till age 63, and CAAC SOUTH WEST has granted it as for current CCAR 121 R5. There is at least one captain, previously employed by the same airline, who has signed a renewal till 63. What will happen with the doctors at the next medical renewal, time will tell.
Once again if the pass the medical is another story !!!!
