Thanks.
Yes, you can. When changing the return portion, the fare difference will usually be $0 as long as you abide by the rules (usually things like day / week + minimum stay restrictions) and if the fare class is still available. When changing the outbound flight, the usual headache causer is the minimum purchase requirement which is no longer an issue for the return.
If your new flights violate the fare rules, the airline will bump you up to the next cheaper round trip fare that you qualify for. They have access to the fares in place when you bought your ticket and will give you the cheapest fare published at that time for your new flights. You will then pay the difference + change fee.
Sorry if that was a bit confusing. Perhaps someone else can explain it better.
Cheers,
