CNC Concourse

Agent-powered travel booking · Early access

Your agent books the trip. You set the limits.

Concourse lets AI assistants search, book, change, and cancel flights on your behalf — every dollar under spending rules you approve, and every big purchase checked with you first.

How it works

Three steps, in order. Your agent does the legwork; the money never moves without rules you wrote.

STEP 1

Set the rules

Give your agent a travel budget: a cap per booking, a total budget, and the amount above which it must ask you first.

STEP 2

Your agent shops

It searches real airline inventory, compares fares, and picks the flight that fits your plans and your rules.

STEP 3

You stay in control

Bookings under your threshold complete instantly. Anything bigger waits for your approval — one tap, then it's ticketed.

Every agent carries a mandate

A mandate is the spending permission you grant — scoped, capped, and expiring. Your agent can never approve, raise, or fund its own mandate. Here's what one looks like:

Spending mandate · Air travel
Allow skye to spend up to $500 per booking
on air travel until Sep 30, 2026
Ask me first above $200
MANDATE FBX-7Q2M ✓ APPROVED BY YOU

Built for trust

Single-use payment cards

Each booking is paid with a one-time virtual card locked to the exact merchant and amount your agent was authorized for. A card can't be reused, and an unapproved purchase can't happen.

A complete paper trail

Every search, booking, change, and cancellation is recorded against the mandate that allowed it. You can review everything your agent did, and revoke its access at any time.
