About Carry‑On Checker

Our mission To help travelers quickly confirm whether their cabin bag meets an airline’s rules—before they leave for the airport.

Our story

Carry‑On Checker began as a side project by a group of frequent flyers who were tired of scouring airline websites only to find outdated or confusing baggage rules. We’d all stood at the gate watching as passengers had perfectly good roller bags pulled and tagged for the hold. We knew there had to be a better way. We started collecting official carry‑on dimensions and publishing them in a simple format. As more friends and colleagues asked for help, the site evolved into an independent resource used by travelers around the world.

Today Carry‑On Checker is maintained by a small team of travel enthusiasts and technical writers. We travel for work and for fun; we’ve flown on everything from tiny regional jets to double‑deck A380s, and we know how different the experience can be depending on the aircraft and airline. Our goal is to translate dense policy language into plain guidance you can actually use.

Who we are

We’re not an airline or a ticket agency. We’re passengers—just like you—who love efficiency and hate surprise fees. Our backgrounds span aviation journalism, software engineering, and customer service. This mix allows us to dig into policy documents, build tools like the Carry‑On Checker, and respond thoughtfully to feedback.

We operate from the U.S. West Coast but maintain a global perspective. When we publish or update information, we cite official sources and ensure that guidelines apply to major U.S. and international carriers. You can read more about our data practices on our Methodology page.
