The solution is to stop paying ground personnel peanuts, hire staff with brain cells and ensure that they are adequately trained!
Been saying this for years. Every new season you get new numpties, because they will not pay to retain good staff. And then they wonder why they shove our wing right through someone else's cockpit. Could have been nasty, that one.
And then you get new Redcaps each season too, which is another hole in the Swiss cheese.
