I book my own work flights and claim the business rewards discount for my company. I offset my last flight booking which I thought would count towards my green tier. I paid the fee and got my receipt. However, it did not credit on my green tier. After many weeks of waiting I got an email response from Qantas FF to tell me that business reward flights do not count towards green tier. I can't find this in any of the Ts and Cs for green tier. I have just booked my next flight the same way and see the offset option offered again. Does anyone know if this is the case? Seems strange - an offset is surely an offset whichever way you look at it. The Ts and Cs that you can access during the booking process are appended below.
