I just noted that some 'Seat only' flight now have the ability to be upgraded to 'Seat plus Bag' online for $10 - similar to the TT upgrade of product options of S->S+B->W->WD. The button on the MyAirNZ flight tab thingy reads 'select new product'.

A small, but nonetheless welcome, enhancement. Of course this may be old news, but I hadn't seen anything from Air NZ on this to date.

Cheers, TK
