I absolutely agree with kiwibigdave on this one.

While flying business class is a delightful change from cattle, you effectively get a much nicer seat (i.e. a bed) and a better meal. For NZ$2800 (or NZ$2100) I could get an extremely nice hotel room for a night and a fantastic meal, and still have plenty of change.

I just don't think that NZ$2000+ is worth just a nice seat and meal. I'd rather spend the money at my holiday destination.
