I had a flight booked in 2020 that I converted to an ‘open ticket’.

I am now beginning to think about rebooking.

There is some basic information here: https://www.emirates.com/uk/english/...icket-options/

The original ticket was the same origin and destination both ways with 2 day stopover in Dubai both ways.

But does anyone have any experience of doing this and what is allowed/possible? For example:

• A change of origin within the UK?
• An open jaw within the same destination zone?
• The stopovers in Dubai?
• Other stopovers elsewhere?
• Is it possible to book Emirates codeshares? Particularly on Qantas?

Separately is there any way of finding a list of which Qantas flights carry an Emirates code?

Sorry in advance of this has been covered elsewhere, I tried a search but struggled to find anything.
