Somebody has posted these on flyer talks as Air Canada is expecting to refresh their brand in 2017. These images do seem to be real as Air Canada is expecting to take a “rouge” like approach with the refresh. With the colours of these uniforms, the rouge like effect seems to be true.
The guy in the suspenders (in the 2nd and 4th pictures) reminds me of the 80s guy from Futurama.
“Don’t you worry about new cabin crew uniforms, let me worry about blank!”
