If BACF falls out of love with LCY, the airport has a problem as BACF has become very dominant there.
Other than Cityjet and Flybe, there are now only 9 other airlines serving 11 destinations from LCY. Cityjet is just a shade of its former glory and may well disappear from LCY completely sooner than later. And it remains to be seen if Flybe will stick it out this time at LCY.
BA seem to be using the aircraft better away from LCY, maybe it's a sign of things to come, it's an expensive airport!
Also during the week? Unitil now, they have simply made use of them over the weekend to work around the LCY curfew and get better utilization out of the fleet.
