Editorial policy

Accuracy first

• Airline figures come only from the airline's official website.
• A value is never estimated or taken from another website. Missing values are shown as not published.
• Each airline page shows its sources and the date they were checked.
• One figure has one source of truth: the same value appears everywhere on the site.

Independence

MyCarryOnSize is not affiliated with any airline. Airlines do not pay to be listed, and their position in the rankings comes only from their published rules.

Written content

Airline pages are assembled from the verified data: every sentence contains a figure or a comparison that is specific to that airline. Official sentences are quoted only briefly, as the source of a figure.

Changes and corrections

When an airline changes its rules, or when an error is reported and confirmed on the official page, the value is updated and the change is recorded with the old value, the new value, the date and the source. See corrections.
