If it were something you were entitled to, you would think you'd even be able to do it as a kiosk.
1. The GA's have more ability to make changes which are inconsistent with fare rules.
2. Some fares allow co-city changes, some don't. Read the fare rules for your specific ticket (unfortunately, you have to do this BEFORE you purchase).
3. IME GA's are more flexible - if they have room on the flight they usually figure it's better to get you out of the airport sooner.
