First scheduled departure was due 06:15, second 06:15, third 06:55... 12 cancelled movements later and the airport decided to state that there had been a problem and moved the flights' status from 'BAG DROP' to something more useful to intending passengers. It's an airport; 95% of its daily business involves moving people. It couldn't perform its primary function for several hours this morning and no-one other than spotters knew it. But that's OK, at least the senior managers didn't have to get out of bed early or anything.
That is up to the relevant handling agent of each airline, not the airport. I would direct all complaints on the flight display system to Swissport. Even at that Swissport will only update each individual flight when each airline informs them of what their intentions are.
Takes time to evaluate the state of the aircraft, get it suitable for towing (cargo needed to be offloaded, on the runway, where no equipment is stored near) so there is quite a logistical task for them to complete.
I can understand though that those who do not have much background knowledge in airports would get frustrated, but there is more to it.. Airport won't put out a press release until the information is correct and they can give some concrete information.
