Flybe certainly know how to hold their share of the market. Ryanair have lost ground to Flybe on the Glasgow route with passenger numbers on the PIK-BOH route dropping since the launch of the daily SOU-GLA last September. I think this is why the Jet2 Belfast route hasn't worked out.
Having said that the stats for April on the CAA site indicate Flybe loosing ground to Thomsonfly on the Malaga route, but we will have to wait a few more months to see how this pans out.
