Editorial Policy

Last reviewed: 3 September 2026

This page explains how the airline pages on FlyRulebook are made: where the numbers come from, who is responsible for them, how often they are re-checked, what tools we use, and what happens when we get something wrong. If a page you are reading does not live up to what is written here, that is a defect — please tell us.

Who is responsible

FlyRulebook is edited and maintained by JK Hwang (황정균), based in Incheon, South Korea. The editor is not employed by, and has no commercial relationship with, any airline listed on this site. Responsibility for every figure published here rests with the editor: if a number is wrong, it is ours to fix, not the airline's.

Where the information comes from

• Primary sources only.Baggage allowances, dimensions, weight limits, and fees are taken from the airline's own published baggage pages, fee tables, and conditions of carriage. Each airline page lists the exact pages used under “Sources” so you can check them yourself.
• Not used as sources: other comparison sites, forum threads, travel blogs, or AI-generated answers. They are sometimes useful for spotting that a policy has changed, but a figure is never published from them.
• No invented precision.When an airline publishes only a combined limit (for example, “115 cm total”) we publish that combined limit. We do not manufacture per-side dimensions to fill a diagram. That is why a few airline pages show a table but no bag drawing.

How a page is built

Every airline on this site is one structured record: allowances, dimensions, weights, fee ranges, known “gotcha” charges, the sources used, and the date it was last checked. The page you read is rendered from that record. This is deliberate — it is why every airline page has the same layout, so you can compare two carriers without re-learning the page each time. When we say a page was checked or corrected, it is the record that was checked or corrected.

How we use AI tools

We use AI-assisted writing tools (large language models) in two ways: to draft and tidy the explanatory text that sits around the figures, and to help pull structured data out of long official pages into a record. We do not use them as a source of fees, dimensions, or policies. A number enters a record only if it can be traced to a cited official page, and the editor reviews and edits drafts before they are published. Nothing on this site is published automatically without a person deciding to publish it.

We disclose this because readers deserve to know how a site is made, and because it is the honest answer to how a very small team keeps more than a hundred airline pages current against sources that change every few months.

Verification and updates

• Weekly re-checks, in rotation.Each week a group of airlines — starting with the most-read pages — is compared against their official baggage pages. Values that have changed are updated and the “last checked” date on that page moves forward.
• We do not bump dates for show. A page whose figures have not changed keeps its existing date, even if that date is getting old. An honest old date is more useful to you than a fresh-looking fake one.
• Unverifiable means unchanged. If an official page is behind a login, geo-blocked, or temporarily down, the existing value stays in place rather than being replaced with a guess.
• Ranges over false precision.Fees vary by route, fare type, booking channel, and date, so we often show a range and say “about”. The airline's own page is always the final word at the moment you book.

Corrections

If you believe a figure is wrong or out of date, use the contact page and, if you can, include a link to the airline page you are looking at. We re-check the official source, correct the record, and the page's last-checked date is updated. We would rather hear about an error than let a page drift.

Rankings and scores

Where we rank or score airlines, the method is published on How we rate. Scores are calculated from the same records described above, not from opinion, and no airline can pay to change one.

Independence, advertising, and affiliate links

FlyRulebook is free to read and is funded by advertising and, on some pages, affiliate links to travel products. Advertisers and affiliate partners have no access to, and no influence over, what a page says. No fee figure on this site is sponsored. The details are on our About page.

What we will not do

• Publish a fee, dimension, or policy we cannot trace to an official source.
• Copy or lightly rewrite another site's content.
• Invent reviews, testimonials, or “traveler experiences”.
• Let an advertiser or affiliate partner change a figure or a ranking.
• Present a guess as a fact. If we are unsure, the page says so.

Limits of this site

FlyRulebook is general information to help you plan. It is not a substitute for the airline's current terms, which can change between the day we checked and the day you fly. Always confirm on the airline's official website before you book or travel.
