I don't get why qantas folk keep whinging about jetstar pax using the qantas lounges.
These passengers pay almost $1000 a year for the privilege, or fly a great deal on qantas as well as jetstar, or pay for points when flying jetstar to keep their club membership.
So at the end of the day, it's not a conspiracy. The group owns the lounges, not qantas domestic or international. The revenue from their operation goes to the group.
As for the rest, I know it sucks, but that's life in aviation. Be part of the solution or go on LWOP and try your luck elsewhere.
