Tickets without change fees are getting rare those days, even in F class.
Rare or very expensive. CX often has reasonable change fees. But the real expense can be fare adjustment when your fare bucket is not available anymore on all or part of the itin.
So check what kind of change fee you can get, rather than looking only for zero.
