Air Berlin will cease its operations from October 18.
It has already opened reservations for the international routes starting from Berlin, Vienna, Dusseldorf, Nuremberg, Hamburg, Cologne, Munich, Salzburg, Stuttgart and Zunich.
Apart from these routes Eurowings is envisaging commencing flights to Mostar from Stuttgart and Cologne from next year. Mostar has been chosen as new destination in a popular vote a week ago.
