About Carry On Sizes

A reference for baggage rules that is actually checked, actually current, and actually says when it does not know.

The problem we are trying to solve

Baggage rules are simple questions with genuinely hard answers. How big can my bag be? Depends on the airline, the fare, the aircraft and the route. Can I take this on a plane? Depends on the item, the country, the carrier and sometimes the officer in front of you.

The web’s answer to this has been thousands of pages copied from each other, most of them out of date, almost none of them saying where their numbers came from. People find out they were wrong at the gate, where being wrong costs money.

What we do differently

Three things, none of them clever.

We read the source. Every figure comes off the carrier’s own page and links back to it. Our verification policy sets out exactly how.

We date everything. You can see when each page was last checked, so you can judge for yourself whether to trust it.

We leave gaps visible. Where we have not verified something, the page says so instead of filling the space with something plausible. This makes the site look less complete than competitors that guess. We think that is the right trade.

How this site is paid for

Advertising and affiliate links. When we recommend a bag and you buy it, we may earn a commission at no extra cost to you. That relationship never decides what we recommend or what a rules page says, and the affiliate disclosure spells out the boundaries.
