I have found some options going through CGK to Dublin (my final destination). Though I may need to lay over for 12 hours or more after paying for a qantas flight fare from Sydney to CGK. I am now wondering if Indonesian open or still closed cause of covid? Will i be allowed to leave airpoirt and get a hotel and come back for the business class flight later? Or does the CGK have a Qantas business class lounge to wait for the connecting flight?
I think there are some residual entry requirements for Indonesia, like evidence of vaccination, etc. Of course that could change one way or the other (tougher or lighter) depending on new variants, etc.
You should have no real issues leaving the terminal. If you are required to stay for some reason, you would not be able to use any Qantas facility as they are the inbound carrier. You’d use the lounge of the airline taking you onwards, ex CGK.
I thought Garuda has resumed the SYD-CGK flights? Worth looking at if it offers better timing.
Finally in the point of ‘rights’… unfortunately we have very few consumer rights for air travel in Australia… nothing like the EU or UK. Qantas. ant really do much more… they are not the ones offering the flight and have no control over partner cancellations. They can offer a refund, but aren’t obligated to do much more.
