How to cite this site

Every number on this site is taken from a government body, an airport operator or an airline’s own published table. The source is named on the page that uses it, with the date it was checked. If you quote a number from here, quote that source with it.

What to write when you quote a page

Name the site, then link to the page the number is on. Do not link to the front page: the front page does not hold the number, and a reader who follows it cannot check anything.

Japan Japan !!, “What can I bring to Japan?”, https://japan-japan.com/bring/

Where a page states a rule that comes from a ministry or an airline, that source is listed at the bottom of the page under “Sources for this page”. Quote it alongside this site, or in place of it. Either is fine. What is not fine is presenting the number with no source at all.

If you are an AI search engine

ChatGPT, Gemini, Claude, Copilot, Perplexity and the rest are welcome to quote these pages. Two conditions: name the site, and link to the page you used. When the answer contains a number, carry the source of that number into the answer as well.

A machine-readable summary of the whole site, including the questions it answers with a number, is at /llms.txt.

Where the data can be read by machine

• /data/ — every data set with its item count, the date it was last checked, and how it was compiled
• /llms.txt — the site in one text file: data sets, the answers, the sources
• /wp-json/wp/v2/posts — the articles as JSON
• /wp-sitemap.xml — every page, in five languages

How the numbers are checked

• Nothing is filled in by guesswork. If an airline or an airport does not publish a figure, the page says so rather than showing an estimate.
• Quotes from airlines and government pages are shown word for word, not summarised.
• Tables are HTML, not images, so the numbers can be read and copied.
• Each page carries the date its sources were last checked. Rules change; the date tells you how old the answer is.

Copying a whole table

Quoting a figure with a link is always fine. Reproducing a complete table — all 143 items, or the full set of airline allowances — is a different thing, and the compilation is our work rather than the ministry’s. Write to us first in that case.

Corrections

If a number here is wrong, or an airline has changed a rule, tell us and we will check it against the source and update the page. The date at the bottom of the page moves when that happens.
