There aren't any change fees to change date, time, flight or carrier. The only fee is if routing is changed (which includes changing a less then 24h "connection" to a stopover).
I've made changes to LONE4's, DONE3's, LGLOB26's and DAS13's with AA, BA, QF, JL and CX over the years for no cost.
I've made one routing change on an LONE4 for no cost, but that was due to rioting in BKK and a number of airlines and governments having wavers and warnings out.
There are however reports of some airlines charging "service" fees to make the free changes.
