Business class fares to Europe that used to be around $7,000 jumped to $11,000 and above. Economy fares seemed to be well in excess of $3000. This of course was a combination of incredible demand meeting limited supply (something that the Australian government didn’t seem bothered about when they blocked extra flights from Qatar Airways last year).
Domestic airfares have come down a little from 2022-23 although I would argue that they are still not back to pre-2020 levels and the recent collapse of Rex and Bonza means there is little likelihood of them coming down much.
