I'm doing some searches for early next September. I'm settled on starting my trip in Dubrovnik/Montenegro and working north. I found one flight connecting in Munich on Lufthanse at a little under 12 hours, another a little under 13 hours and a bunch of choices longer than one day.
I can live with 11 1/2 hour duration but 25 plus hours sounds like hell.
How are people here getting there? What is your flight duration and where are you connecting?
