easyJet, at STN domestic term, have a habit of setting the FIDs to Final Call, before the aircraft has even landed.
Yes, this is a particularly annoying habit (found elsewhere too) where you rush along to the gate changed from Boarding to Final Call and up to the agent only to be treated like an imbecile (even more than usual at Stansted) as the incoming aircraft is not even on stand yet (on one occasion at STN it sat at Final Call for an hour after delayed boarding/departure too).
If only BAA acted as real airport managers, rather than shopping centre developers, they would ensure that all their tenants acted in a responsible and accurate manner in all information aspects. But they couldn't care less and the tenants thus take their cue from them.
