Thanks AirWin, I found them too and its probably the best direct option but I cannot find flights after Nov 17 or they are not loaded.
I have done the google fights, Expedia etc.
Last year we did SYD, LHR, Barcelona which worked and we had some time in the arrivals / departure lounges but it did add extra hours to flying.
Next year SWMBO is singing (with a Choir) in Berlin and other former republics of the Socialist Soviet Union for 2 weeks, so nice places with a lot of history. She does not like travel as much as I do and I will join her later in the tour after several connections, planes and airports

After the tour we will be in the DSA (UK) for a week before coming back to Oz. Planes don't help her voice too much (too dry or too much Champagne) so Qatar is probably the best option if the flight is available.
So I am looking for efficient transfers and easy travelling for her but returning out of the UK. She is gold OW.
Appreciate any suggestions
Does anyone fly regularly to or from Berlin? or suggest how to get there.
