I'll bite. How is this to do with Brexit? My local airport is not in Britain but has been a shit-show for months. My understanding is that this is true for several major European airports. Can I blame that on Brexit too?
Very plausible that people from other EU countries who worked in airports left, and it’s a reduced pool of people willing and able to take on those jobs today because of Brexit.
So it clearly isn’t the cause of airport chaos, but it can’t be helpful.
