How we check

Bag size is the maker’s listed outside size. When a maker prints inches and centimetres that disagree, we use the larger.
Airline limits come from each airline’s baggage page, checked on the date shown.
Sides are compared largest to largest, the way a bag goes into a sizer.
“Fits if not packed full”: a soft pack is at most 3 cm too deep and fine on the other sides. More on the method.
