Great, thanks so much.
By chance do you happen to know about AA voucher utilization on RTWs?--specifically in this case I was told by an agent that I could only apply an AA voucher to the ticket if both transoceanic flights were on AA metal. But the AA voucher conditions seem to state that they are valid on AA as well as all AA codeshares. Just on the off chance you have any insight into that, thought I'd ask.
