I really can't see that BmiBaby will start operating a BCN unless they plan to do it on the back of the first a/c back for a night stop which will be approx 22:10 departure. With the current schedule i really can't see the IBZ returning either eve though it was very popular.
However if they move the BFS to a 22:10 departure and place it on the back of a different flight, then it will be possible to operate another international on a weekday with a departure of 20:40 which was similar to the IBZ departure last year.
Unless a 4th a/c arrives which is possibly unlikely then don't think were to expect any shocks.
CWL Passenger Figures for Today
Was talking to one of the guys at security and he said we were expecting less than 800 passengers in the airport today from all carriers, this compares from over that figure daily from BmiBaby alone in the summer.
Hopefully Flybe will be able to pick that up in W08
