Two of us are planning to go to NZ next year in Feb or March and am looking for thoughts on the best value way to get there and back, most or all of the way on a flat bed (a must).

I have a couple of companion vouchers, plenty of Avios, but realise that getting two reward tickets in First or Club to Sydney are next to impossible, so am trying to work out all our options.

I know nothing about the likely impact of BA sales, Ex UK flights etc etc as I am a simple man, so have either paid full fare or use companion vouchers/Avios in the past. However I did have a quick glance at flights via Sydney in Club Class on BA and it was rather a lot of money!!

Would be happy to go via an SEAsian city for a stop over.

Any advice gratefully received
