Have probably jinxed myself. Trying to book a reward flight out of XPL (Honduras) which is a new airport (eventually will replace TGU).
AA availability XPL-MIA-onwards in T (Y reward), QF CPT can see it, they can price the taxes, but XPL throws an error. The second time I called the agent managed to issue a PNR that I can view, and even view on AA - but it's unpaid. Agent said same issue, XPL throws an error. But at least I have a booking which is easier for subsequent calls.
Trying to use the reward escalations email to get someone to fix it but no reply after 48 hours, tried to call again this morning but got CPT again.
Seems the only issue is working out how many points to charge me, everything else is fine, it's even showing up in my QF and AA apps.
