# Liquid Limits — Full LLM Reference

> Liquid Limits helps travellers check the strictest airport cabin liquid rule for their whole trip before they pack — outbound, return and any connection.

This is the expanded LLM/answer-engine reference. Plain text. Mirrors the
public, indexable surface of liquidlimits.com. Internal/admin pages, paywall
upsell pages, saved-state pages and report forms are intentionally excluded.

## How facts are sourced

Every airport rule on Liquid Limits is graded by source confidence:

1. Airport-specific source — the airport's own website or security page.
2. Airport-operator source — e.g. Aena for Spanish airports.
3. National authority — e.g. TSA (US), GOV.UK / DfT (UK).
4. Regional fallback — e.g. EU 100ml baseline.
5. Needs source — no verified source yet; we default to the 100ml baseline.

We never claim airport-specific verification for inherited guidance. Where
an airport-specific rule is unknown, the site says so and recommends the
conservative 100ml-per-container default.

There is no "updated daily" claim anywhere on the site. Each page exposes
its own `lastVerifiedAt` date when a verified source exists.

## Machine-readable summaries

Every indexable content page includes a JSON-LD `<script>` with
`@context: "https://liquidlimits.com/schemas/page-summary"`. `pageType`
is one of:

- `airport_liquid_rules`
- `item_hand_luggage`
- `route_liquid_rules`
- `country_liquid_rules`
- `can_i_take`
- `guide_liquid_rules`

The same facts are visible to humans in a "Short answer" block at the top
of each page (rendered server-side, not behind JavaScript).

## Editorial policy

- No invented airport rules. If we can't confirm an airport-specific rule,
  we say so and default to 100ml.
- No fake verification. Inherited guidance is labelled as operator,
  national or regional, never airport-specific.
- Conservative language for unknown rules: "We haven't verified...",
  "Pack to 100ml until you can confirm with the airport."
- Liquid Limits is a travel planning tool, not an official aviation source.
  We always recommend confirming with the airport before you travel.
