Brussels Airlines to partner with Africa World Airlines
 

Africa World Airlines (AWA), the Ghanaian airline based in Accra, and Brussels Airline, the member of Lufthansa Group and a Star Alliance member; have announced an interline agreement to better serve the traveling public.

The new partnership between the airlines will allow passengers traveling from Brussels Airlines’ network of 73 European and 21 intercontinental destinations to book a single ticket to any of the 9 African destinations served by AWA, including attractive fares, a single intercontinental baggage allowance all the way through the different legs of their journey.

Perhaps this is a silly question, but does this mean that LH will also interline with AWA?

Not exactly, but LH flights booked under the SN code can be interlined.
