I had booked First Class tickets from Lax to Newark and a return from Washington DC to Lax. Due to ill health I had to cancel. When I rang AA they told me the fares were not refundable but a credit would be available for a new fare until February 19. I asked if I could use the credit towards a codeshare on Qantas as i was thinking of going to NZ from Sydney this year. The rep told me that the credit could only be used on fares originating in the US. I have tried to find the T& Cs to confirm this without success. I booked the fares on the AA Australian site using AUD. Is there anyone with some experience similar to mine that might shed some light on this for me. Thanks in advance
