EasyJet - Cheap flights from Berlin to Nice

EasyJet flies cheap flights from Berlin Shoenenfeld (SXF) to Nice Airport. The best prices available at the momen are:

• April 2011: 58,99€
• May 2011: 58,99€
• June 2011: 47,99€
• July 2011: 47,99€
• August 2011: 33,99€
• September 2011: 33,99€
• October 2011: 33,99€

I find it slightly surprising that german Air Berlin is not flying from Berlin to Nice at all. Air Berlin flies their cheap flights from Germany to Nice from Düsseldorf.
