On the topic of Pisa, this is another route that has failed to deliver at BHX, not quite on the lines of Cologne but My Travel Lite and FR have tried it and even before we get on to yields, load factors at best were average.
I find that really surprising; I flew MAN-PSA in Sept with Jet2 and the plane was full, I think EZY from Bristol offer x5 weekly flights and FR from STN can be as many as x3 daily at peak times. Another case of pax leaking out to other airports.
