I definitely agree with the comments that the engine should allow booking to destinations where there is a published NZ fare (eticketing requirements permitting). NZ misses out on my revenue if I can't book online, to e.g. Ottawa.

Also I would like to see the ability to book to partner destinations using a mix of Premium Economy on NZ and economy on the partner airlines with the multi-stop tool. I can't do that today (I want to go AKL-LAX in PE, then LAX-xxx-YOW in Y).

A wider choice of routing would be nice too.
