Hello HN and sorry for the potentially OT question.

I am required to travel a bit for work, including domestic (US) and international, and would like to optimize my life a bit more by making sure I never have to check luggage on a flight even when I have to stay away for a week or two, it's just too time consuming and error prone.

I am thus in the market for a good carry-on with optimized space. As I started my research, one obvious design choice is to go for a two wheels rather than a four wheels, since the space in the second one seems to be much more efficient (sadly, the market seems to overwhelmingly prefer the former option).

Currently eyeing the TravelPro Maxlite 5 international expandable carry-on [1] with a declared 45L capacity, but was wondering if any experienced traveler has some interesting recommendation.

Thanks and Happy New Year!
