my (smallish ) company has a fuel bill amounting to between 100 to 500K per month (anecdotally and by multiplying one of the big fuel suppliers invoices by three to approximate the total fuel bill) Since AirNSN operates 10 times the aircraft with great big thirsty PW100s I assume that they would be paying in the order of several million dollars per month for fuel even with AirNZs massive discount for bulk orders in US dollars!
If you compare that with their wages bill the claims that pay rises for pilots are unaffordable is just an embarrassing joke.
While I'm at it..the big Koru needs to look seriously at they way it treats its staff at the big Airports (ramp, loaders, check in..) They are not working well as a team..seriously demoralised, and deserving of much more financial support.
