If the card is in the enRoute magazine, will people have to tear out the page every time they take the plane? Come on! The card is there if you want to file a complaint; it's there if you don't want it. It stays there. No one's forced to do anything, but that affords the opportunity to do so. Air Canada is governed by the Official Languages Act. It's the law. Its representatives always say that other airlines don't have the same obligations, but it must be borne in mind that, when Air Canada was bought, they bought the whole package. The official languages had to be respected.
I believe I've said enough. I would like to hear from my colleagues.
