While IATA codes do not require a consistent prefix, all the Canadian airports start with Y: https://en.wikipedia.org/wiki/List_of_airports_by_IATA_code:_Y htt

  Interesting. I still see Canadian airports starting with Z. But Y is heavily Canadian. We should all just start our own airport. Sounds like a good way to learn about naming. I imagine we will want an airport code staring with YC, so it'll have to be in Canada :P
