I have the answer!!!! 340 Dog, you are really close.
Stop printing everyhting twice, except of coarse in Quebec.
Now all that ink used for french, it must weigh something. So, all the ink that the airline has wasted money on printing, what would that equal in fuel savings if All Air Canada A/C did not have that extra ink (weight) on board? ( Except of coarse the A/C going to Quebec.)
Voila!! They may just save enough to bring up their bottom line.
Save on ink, save on gas. Two birds with one stone.
