Thanks
Thanks for all of the advice.
After a weekend of trawling flight prices and options, and taking on board the comments from PPRuNe we have booked the whole trip with Air New Zealand. I certainly prefer the idea of one carrier to sort out any problems.
We are flying from LHR to HKG on 9th December stopping over a couple of days and then on to Christchurch via Auckland. We return between Christmas and New Year with a 3 night stopover in LA.
We managed this booking with the lowest prices quoted, spending Christmas with our family and free stopovers too, so I'm pleased with the outcome although my wallet is smarting a little.
So now just to work out the details of our stopovers in Hong Kong and LA - any suggestions?
Thanks again
