Canadian airport IATA codes
Got an email from a friend of mine, and he asks this question ->
"Hey Bill, how come the Canadian IATA codes don't bear any resemblance to the names of the cities in which they are located?
Los Angeles is LAX, Kingsford Smith in Sydney is SYD, Wellington is WLG ... Toronto is YYZ?
Did some IATA official suffer childhood abuse by a Canadian?"
Ideas?
