When KA, with their stated training surplus, are doing all CN upgrades for CX next year it will solve both the KA CN shortage and the training difficulties at CX. Then we will have CX captains on CX COS flying KA aircraft, just as the precedent has been set with the JFO upgrades. Yet again TTW for CX! If I was a KA FO that was purposely delaying command, I would be in the office ASAP and getting on a course!
