I'm half way through a ticket at the moment but I need to change the remaining flights to next year... It's an AA issued ticket (if that makes any difference)...
QF told me the ticket is valid for one year from the first flight, but they couldn't change it because it's an AA ticket. (QF actually thought it's 12 months from issue date as well, but she double checked and said it's 12 months from first flight.)
AA told me it's only valid for one year from the issue date.
Who's right?
From the FAQ here, it seems to me QF is right. This is the closest I can find in relation to this topic.
Q: What happens if the rules on my ticket change, or are about to change?
A: If the rules change before your ticket is issued, then the new rules will apply and you will have to change any existing reservations that are not permitted under the new rules. If the rules change after your ticket is issued, the rules that apply are those that were in force when your ticket was issued. But be aware - if after the rules change you want to cancel the ticket, or to do something not permitted under the old rules, then the ticket will be cancelled and reissued, and the new rules will apply. If you are worried about rule changes and want to maximize your flexibility, set your last flight to be 12 months after the date of your first flight (which is permitted). This gives you 12 months' worth of flexibility once you start travelling since date changes are currently free of charge. To give yourself even more flexibility, get your ticket issued up to 12 months in advance of your first flight (which is also permitted), which gives you an effective 2 year lock on the rules as long as you don't change that first flight.
The OW web site says I have 12 months to complete my trip, which I take as 12 months from the first flight.
I've also asked my original agent to clarify...
