All of the EX-EU flights I've had to make changes to after departure had changes fees much lower. Quick look at saved fare rules shows 100€ on some V fares and 130€ on an L and a K fare. My guess is that EU laws might limit the changes fees.
*edit* though looking at how cheap his fare was, doesn't look like even the lower change fee helps much, unless rescheduling the return to a later date (and being able to use it) is a possibility. Some of the tickets reprice using historical fares, but without the fare rules, only way to tell is doing a dummy-rebook.
