Winter flights to Krumovo?

Does anyone know who flies in the winter to Krumovo aerport? Maybe a companyname would be handy. I would like to go to Pomporovo but with a flight to Krumovo. I know some people over in Krumovo. Sofia is to far away.
Possible departure is from: Amsterdam/rotterdam/Brussels (Zaventem) or Koln-Bonn aerports. I'm coming from Belgium.
