After being on the phone for 50 minutes with AA AUS I was able to put on hold the following: CX F HKG-JFK (in November), now I would like to add a leg from SYD to HKG, but there's no reasonable flight available, will I be able to add it after the devaluation? or if I add one in Y will I be able to change it after the devaluation to J when it opens up?
