Maybe the perfect solution when flying business would be to have 2 Cabins, as this is the limit for business ticket. You have plenty of space, without the risk of checking your bag. But it is also much mess comfortable outside the plane, as you will have both hands occupied.
I think you're right. Cabin Plus is the better choice here. I mean, based on what people are saying on here and Reddit, most folks have been able to board with their Cabin Plus in Asia, Europe, and in North America on most legacy (and even some low-fare) carriers. I think that I'm just getting in my own head because, visually speaking, Cabin Plus just looks huge compared to my TUMI International Carryon in black. I would get the Cabin Plus in back, but apparently it does NOT age well in terms of the scratching and color coming off.
