What I hope people learn from the Delta crash at YYZ:

• wear proper shoes and warm clothes; you might have to climb out into the snow;

• keep seatbelt fastened until the plane arrives in a full upright position at the terminal;

• passport, glasses, wallet in your pocket. no hunting around for your carryon in an evacuation;

• listen to the flight attendants, they’re amazing.

I am a little curious how the Canada Border Services Agency handles something like this. How do you clear the incoming transborder passengers who are all wandering around on the tarmac, some of whom have been evacuated to hospitals, etc.

Years ago, an Air France plane skidded off the YYZ runway next to Highway 401; again, miraculously, all the passengers got out, but some wandered onto the highway and flagged down passing cars. Then what? Hmm.

On the wearing-proper-shoes thing. Yes, perhaps your flight is departing from a warm place. But it might make either a scheduled or emergency landing in a cold place. (last May, Air France from Paris to Seattle landed in Iqaluit. Surprise!) Be ready.

You, over there, wearing shorts and sandals on a trip back from the Caribbean to Canada in February. Don’t be a dope.
