Please excuse this intrusion from an American Delta flyer trying to book DL award seats on VA. If I run an ExpertFlyer availability search on AKL-SYD DJ51 for my target date, the search returns H1. If I run the same EF search using VA51 instead of DJ51, EF returns H9. Does anyone know the reason and which is the correct answer ? The DL res agents I've been working with are totally clueless on this and I'd like to know if H seats are actually available and to suggest using VA or DJ before I call DL back and try to walk them through this reservation. Thanks for any help or insight.
