I had mailed the Kingfisher airlines asking an explanation as to why the flights have been cancelled from Belgaum.
Here is the Reply I got –
With regards to your email, we would like to inform you that due to operational reason flight Bangalore to Belgaum is cancelled from 17th June 2009.

We look forward to being of assistance to you.
Operational reason will be lack of traffic on the route and nothing else I guess. The aviation industry on a whole is in turbulence and hence the best way to survive is cut costs and to cut costs stop all the routes where there is not profit.
