One tool for three packing headaches
Every trip has the same three packing questions: What should I bring? Will my toiletries pass security? Will my bag fit in the overhead bin?Most people answer them with three different searches and still pack wrong. This tool answers all three on one page.
The 100 ml liquids rule (and why your travel-size still fails)
Each container of liquid, gel or aerosol in your carry-on must be 100 ml or less and fit with everything else in a single resealable bag of about 1 L total capacity. The size on the container counts, not how full it is — a half-empty 150 ml bottle still fails. Pour into 100 ml travel bottles or move it to checked baggage.
Carry-on sizes are not standardised
Airline carry-on limits range from 40×20×25 cm (Ryanair, free bag only) to 61×41×28 cm (Southwest). A bag that flies free with one carrier can be charged or gate-checked with another. The Luggage Size tab shows pass/fail across 24 major airlines so you can pick a bag that works on every airline you fly.
