The Canadian airline that I used weighed my bag: Exactly 23 kg (50 lbs) as I kept adding stuff and weighing it till I hit 50 lbs.
Much to my surprise, in addition to the scale, they also had this bar running over the scale / belt: if the suitcase didn't fit under this bar, it's oversized. $$$ Without the wheels, the Vincita passed. I'm not sure if the B&W case would pass as it exceeds the 62 linear inches rule.
