Here's the situation: I'm on a vacation - perhaps for 3 weeks - and the need arises for me to return to the point of origin for a short time - perhaps one day (a business emergency). So I buy a return ticket back to the point of origin and, upon return from that trip, resume my vacation.</font>
In theory - AC would expect you to pay a change fee to move up your return date. Then buy another ticket to resume your vacation.
