QF has xONE3 fares out of Australia showing in EF

LONE3 for AUD3299 (the LONE4 is AUD3899)
DONE3 for AUD10499 (the DONE4 is AUD11999)

there is no AONE3 published - I guess because none of the airlines have first class cabins on southern hemisphere routes

Edited to add:
QF also has filed xONE3 fares out of AKL, but nothing showing out of JNB or SCL as yet
