I am trying to book a one way Bus. class from Europe back to Perth using Asia Miles 23-30 Ag 2016 but he first leg with Qatar always shows full even though the Doha to Perth show seats. I have tried ex London, Paris, Munch, Frankfurt, Athens, Amsterdam and Istanbul but they always show fully booked with Qatar. Does anyone know if Qatar normally open up more seats near to departure? I have not used Asia Miles before, can anyone help?
