# Fast track and security

Security fast track where a supplier returns a slot. The routed ids are anc.fasttrack.search, then anc.fasttrack.book.

Book only where the supplier returns a slot. A search with no slot is an empty result, not a guess, and nothing is billed.

Routed: `anc.fasttrack.search, then anc.fasttrack.book`.

The price is quoted on the call, at the supplier's rate, with 0% markup. This page does not publish a rate card.

Contract: https://ancilair.com/llms.txt
API: https://api.ancilair.com
MCP: https://mcp.ancilair.com

## What's the best way to ask?

Setup line (paste into any agent): `set up Ancilair — https://ancilair.com/llms.txt`

Then ask: "Using Ancilair, search fast track for the airport, date, and party I give you. Read https://ancilair.com/llms.txt. Call anc.fasttrack.search on https://api.ancilair.com. If there is no slot, say so. Do not book until I say yes."

- One token. Supplier credentials stay on the server.
- The price is the quote on the call, at the supplier's rate, with 0% markup.
- A contract the team already holds is never metered, and it wins over Ancilair's account.
- A quote, a search, a plan list, or a requirements check is not a booking. The follow-up runs only after an explicit yes, with an Idempotency-Key.
- DragonPass documents the same prebook window as lounges, about 2–3 hours before departure.

## Suppliers

### DragonPass

Fast track is its own module on the same partner API as lounges. Check availability, then create the order.

- `dragonpass.fasttrack.search` — Airport resource, date, adult count, child count.
- `dragonpass.fasttrack.book` — The prebooking token from the search. Idempotency-Key required.

### Holiday Extras

FastTrack availability and booking on the Holiday Extras partner API.

- `holidayextras.fasttrack.search` — Airport, arrival date, arrival time, adults, children. Returns a fast-track code and a price.
- `holidayextras.fasttrack.book` — That code, with the same party and time. Idempotency-Key required.
