If not then why are they full?
Because Thomson Holidays chartered a Spanair A320 to operate the Saturday Reus from BFS, and for one reason or another, potentially low loads due to TUI operating to Reus already with Thomson Airways during the week, they wanted to down size aircraft, hense FlyBE at BHD. This was only finalised a matter of months ago after many of the passengers already had their holiday booked thinking they were flying from BFS.
As regardless of my username, I think that BHD can play an important role as a REGIONAL airport. FlyBE is the perfect airline, connecting BHD to the regions, aiming manly at the business market.
I detest Ryanair, and even more so operating at BHD. Within the context of Northern Ireland, especially the two Belfast airports, I really find it very hard to see any great benefit. Already good competition, prices sustainable and reasonable service offered. FR has added nothing to this.
