CarryOnSizes helps travelers choose the right bag and understand what they can take with them. We focus on airline baggage policies, security questions and luggage buying decisions.
Useful before you leave home
A suitcase label does not tell the whole story. Wheels, handles, fare restrictions and operating airlines can change the answer. Our guides separate those details so you can check the part that affects your trip.
How the site works
Policy guides link to the airline, airport or regulator behind the rule. Buying guides distinguish published specifications from customer feedback. We do not claim to have tested a product unless that testing is documented.
