And what if none of the manufacturers offer that option?
I am aware of other things, made in and by non-English speaking places, specifically for non-English speaking markets often still have English as the
only language on their stuff, simply because that's how it comes or that's what the schematic showed...
Besides, this is Air Canada, not Air Quebec, and only about 20% of Canada speaks French as a primary language. Moreover, I presume that people will be taking AC flights from other countries
to Canada, with many of them likely speaking English as well, so it makes more sense to use English as the lingua franca... especially on things like seat belts where you may only have enough reasonable space for one word....
However, I will revise my earlier assertion by suggesting Air Canada respond with something
more stereotypically Canadian, such as "Take off, hoser"!!
