Hi,
Thanks to all those who replied - As I thought no consensus.
I keep moving between open and dummy - I suppose the question is:
For a novice traveller who will be travelling for a year on this ticket and flexible with dates and does not understand for example what a validation sticker, or a PNR is - would I be better of getting dummy dates or open.
One thing for sure is that my travels will be set in stone with regards to SCL-AKL availability which does not exist in L though looking at the class availability sites seem to be ok for D.
Thanks
J
