Does anyone have a suggestion of how I can get from Berlin to Dubrovnik cheaply sometime between Sept. 5-10? I have been searching for a week and can't find any good solutions! Your advice is greatly appreciated.
Welllll... how do you feel about flying out of Hannover?
TUIfly Airlines has a rate on 08 September for €61 (including taxes).
But I'm really going out on a limb here - I've never used TUIfly Airlines myself, and don't know anything about them. I assume they are a budget airline and may tack on tons of fees for baggage, in which case it may not be a very good deal at all.
And then there is the issue of flying out of Hannover...
It looks like EasyJet and Germanwings fly between Berlin Schoenefeld and Dubrovnik but flights don't seem to be available for the exact dates that you posted. I'd try to play around with the dates to get a flight that will work for you. Angela's suggestion about flying out of Hannover would be one I'd consider. Good luck!
The Germanwings site shows a direct flight on 6 September and an indirect flight via Cologne-Bonn on 10 September.
