I've noticed multiple oddities on the NZ (UK) website in the past few weeks, such as:
- Not offering a split NZ1/NZ5 NZ2/NZ itinerary LHR-LAX-AKL, until a few days ago (the primary reason for choosing a split itinerary is it can save over £1,000 in premium classes or can be the difference between getting an upgrade or now)
- Not offering PE on LHR-HKG-AKL for CX/NZ, although there is clearly availability seen on other websites
- Selling VS-NZ combinations with a PE search, when the VS leg is in economy and this isn't clear until the payment stage by looking at the flight choices at the top (the fare description calls it "global premium economy saver").
