Qantas touting for cash upgrades at gate?

[AuSammy]

Just out of interest “At Airport upgrades,” are now listed on the QF website for all international and domestic flights from Melbourne. View attachment 522291

Interesting they say “cash at the airport”. Would like to see the reaction if someone actually turned up with cash and not credit card.

Cash has a surcharge after RBA rule kicks in I read somewhere Qantas loves a good surcharge more than most, to a point of, well fill in the blank

One bar… are you with Vodafone? Hahaha!

You’d think so but nope. That’s how good Telstra’s service is at my place about 7km from the Adelaide CBD.

Got the same info in a recent email from Qantas.
Any idea why domestic cash upgrades are only available at Melbourne?
From a technology/systems perspective, wouldn't all airports be using the same system? I can't think of a logical reason why this would be rolled out to one airport, and not all?
