How about this:
Booked AKL-NPL one way. Then a client in Wellington wanted me to run through something in person so TA changed it to AKL-WLG-NPL (same day). My corporate traveller booking shows two separate sectors with different fare amounts for each sector (rather than one fare if it was a single journey with a connection in WLG) and different booking classes, and my potential SP earn is split out into two separate sectors when I look at it. Will NZ treat that as AKL-NPL? Or as two separate sectors?
