What the best way to get from Dubrovnik to Cologne?

Nonstop flights taking a little more than 2 hours on Eurowings for as little as $84 wins hands down. But don’t wait too long to buy seats at this price because other airlines charge twice as much for flights taking twice as long— which means these seats will soon be gone . You can see what else is available at www.Skyscanner.com

In June there is a weekly nonstop flight from Dubrovnik to Cologne. In addition, there are 2 weekly nonstop flights to Düsseldorf (40 to 50 minutes by train to Cologne) operated by Eurowings.

Flying out from Split the choice would be bigger. There are daily direct flights to Cologne or Düsseldorf operated by Eurowings and/or Condor.

Thank you so much for your help! We shall look into this.
