Luggage: Inches vs Centimetres at the Gate
Airline carry-on limits and most EU-seller listings are quoted in centimetres, US listings in inches, and a bag that is "carry-on size" in one system can miss the sizer in the other by a finger's width. Convert the three dimensions above before you buy. If you are replacing a bag, Time4Now's luggage timing guide shows the two travel lulls each year when suitcase prices fall hardest.
