What Are Carry-On Bag Size Requirements: Detailed Explanation of Airline Standards
A carry-on bag can look perfectly normal in a product photo and still create trouble at the airport. The problem is rarely the word “carry-on” itself. It is usually the gap between a bag’s marketing size and its real outside dimensions once wheels, handles, padding, expansion panels, filled pockets, and other fixed components are included. Airlines also use different dimensional limits, and some apply weight restrictions or fare-specific baggage allowances that change what a passenger can actually take into the cabin.
