Qantas airlines - open return tickets are not allowed  https://qantas.custhelp.com/app/answers/detail/a_id/392 https://qantas.custhelp.com/app/answers/detail/a_id/3417/related/1/session/L2F2LzEvdGltZS8xNDAzNzEzNDUyL3NpZC9wbDVJVUlYbA%3D%3D

One will have to call up the customer service department of the airline one wants to travel with to check whether they have option of open return or not. Almost all airlines nowadays have Fully flexible, semi-flexible ticekting options which allows the traveller to change/modify the flights which might come at some cost and rules differ from airline to airline.

Open return tickets are not completely out of the door but it seems most airlines have atleast started showing it the exit door. Atleast i have encountered or found any airline who allows us to see prices for open return flights online and i am pretty certain they would cost a fortune to book nowadays.

The closest option to open return tickets are semi-flexible and fully flexible type options with airlines but one needs to be careful as there is a lot of fine print (different for each airline) which one needs to be aware of before actually making the booking.
