I don't think everything is yet completely cut & dried at Flybe for Summer 05 yet.
I want to use SOU-PGF for a family holiday next May, so was keen to get on their site and get the best prices today.
The route map shows it as a route, but it's not available in the booking engine.
A call to their Call Centre reveals that SOU-PGF and BHX-PGF are under review, and will be available (if they're going to be offered) after 15th Dec.
So why not say that on the website?
