About MyCarryOnSize

MyCarryOnSize answers one question: will my bag be accepted in the cabin? It compares the size and weight of your bag with the carry-on and personal item rules of 80 airlines.

Why this site exists

Carry-on rules differ from one airline to the next, sometimes from one fare to the next, and they change. Many pages online repeat old or rounded figures without saying where they come from. Here, every figure comes from the airline's own website and shows the date it was last checked.

How it works

• Only official airline pages are used as sources. Nothing is copied from other websites.
• Figures are stored exactly as the airline publishes them, in centimetres or inches, kilograms or pounds.
• When an airline does not publish a value, the site says so instead of guessing.
• The checker runs in your browser: your measurements are never sent to a server.
