Whilst I have to agree with TopBunk, some routes seem to be used more often than others. There is no guarantee that the undermentioned route will be flown but it is one of the shorter ones if all other conditions are favourable.
North of Manchester, direct to the north Norfolk coast and straight on to close to Amsterdam. Continue course to around Arnhem/Nijmegan then turn slightly south and direct to Munich. Turn direct to Ljubljana with a final turn around Salonika.
No guarantees of course.
Have a good flight.
