I typically travel in the US and Asia, so I’m not as familiar with cabotage policies in Europe. My gut would tell me this is disallowed; it would seemingly allow loopholes related to things like VAT refunds, or cause issues for people with single entry Schengen visas.
But BA lets brings up itineraries for ATH-LHR-LIS, as an example, so maybe it’s not prohibited?
It is certainly not prohibited
You will need to have the correct passport/paperwork to
1/ enter schengen again and
2/ transit the 3rd country
A single entry schengen visa would be a problem as you would have left schengen
some passports may require even airside transit visas in a 3rd country
it is up to the passenger to ensure they have appropriate documentation when they make the journey (which they may not have when they book) , otherwise they may be denied boarding
i have residence in a schengen country and a UK passport so I could make the journey you described without any issues
my russian friend on a single entry schengen visa could not make the journey
