The sun routes that they operate though do tend to be from airports that don't really have a LCC base. EXT, SOU, DSA and NWI don't have LCCs like EZY or FR operating out of them so Flybe are filling in a gap and catering to local demand. CWL is slightly different as their only sun route is Faro and their focus tends to be on more on Italy and Germany. With their other bases their sun routes do tend to be charters rather than them going up against the others. So i'd be surprised if they keep the jets if they would ditch them if they are making money.
