Hello, has anyone booked a one way ticket to New Zealand with Avios points? I can find a ticket to Singapore and would be happy to pay onward flight, but wondered if there is another option (eg someone said going via America?) Also, if I book and pay for return flight with BA to Auckland, is it possible 1) to upgrade from Economy to PE with Avios points 2) book an 'open ended' ticket. If not possible to book an open ended ticket, is it possible to make the return date quite a distance in the future and change the ticket when I know what date I will be returning? Just making initial enquiries really, and wonder if any of you knowledgeable ladies and gents can help. Thank you.
