comparison
I am Gold Elite with Air NZ and Platinum with Malaysia Airlines. This year I have received nothing as a thankyou from Air NZ, however Malaysia very kindly have me vouchers worth NZ$125 to spend on in flight purchases on my next flight.
I have cut my air NZ flights by 66% over the last 2 years and fly the minimum to maintain GE status with Air NZ. The customer experience just doesn't bear comparison with MH.
