# Find a lounge

Airport lounges from suppliers that sell a visit through a partner API. The routed ids are anc.lounge.search, then anc.lounge.book.

A search is not an entry pass. If the supplier has no slot at that terminal, the response says so and nothing is billed.

Routed: `anc.lounge.search, then anc.lounge.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 lounges at CDG terminal 2E on 2026-10-14 for one adult. Read https://ancilair.com/llms.txt. Call anc.lounge.search on https://api.ancilair.com. Show the quoted price. 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 prebook time as about 2–3 hours before departure. Walk-in access does not use the availability search.
