The fare for a flight to Berlin includes bonus miles, the possibility of hold luggage and a variety of catering services, valid for all flights.
I have searched Bucharest - Berlin - Bucharest for the period 23 debruiera - 26 February and I found at 99 EUR. I think it is a good price for a small stay in the German capital.
Numerous exhibitions, fairs and events are scheduled throughout February. So you won't have much time to get bored in Berlin. Pleasant trip!
