I bet your airports don't close for a whole day like ours.
"Airports" is an overstatement, it's more or less only BUD... It's a big fashion to bash the airport for being unable to cope with snow but they have at least 20 ploughs (and the luck of having 2 runways) therefore closures beyond 30 mins are quite rare (= 1-2 cases/year). We'll see it in the morning btw, 2-3 cm of snow came down in the last hour.
