It's 'Qantas'... "Queensland and Northern Territory Aerial Services"

Shouldn’t it be QANTAS

Regardless of its actual origins as an acronym, it’s a company name so the correct answer can be whatever the company chooses it to be.

I believe the widely accepted (but not universal) format for acronyms is all caps if each letter pronounced...for example MIT. Only the first letter is capitalized if hte acronym is pronounced as a word...for example Nasa.
