I like the Westjet ad. I really don’t see what’s bad about it. I also don’t see what’s wrong with the three/easy ad either.... in fact I actually like it. Though, as it’s a three ad and has the continuing three ad theme, easy can’t really take the credit for it.
As for boarding on starboard side. Only a relative few plane geeks would ever notice. I would hazard a guess it’s to suit production values. It doesn’t really matter though does it.
