DCF I think your missing the point here.

I think you would be aware that the target market for AKL-OOL-AKL is mainly leisure travelers. Just because your family of 6 useing the Bussiness Class x amount of times a year, doesn't mean the rest of the time its empty & losing money.

Does it really hurt to fly 3hours in economy? its more comfortable than being stuck in a 2h30m Auckland traffic jam.
