In May 2015, InterSky announced plans to open its second base at Memmingen Airport by October 2015 consisting of one aircraft, adding a new route to Cologne and increasing frequencies on existing services to Berlin and Hamburg. Later, the plan was changed to use a triangled route Friedrichshafen - Memmingen - Cologne/Bonn instead of basing an aircraft in Memmingen. On 27 October 2015, InterSky announced drastic cuts to their Friedrichshafen-Memmingen-Cologne route which had resumed just three weeks earlier. Instead of two daily flights only two flights a week were to continue due to demand being lower than expected.
