Negotiated corporate rates on flight searches

If your org has negotiated rates with one or more airlines, the Corporate Rates drawer on /travel surfaces them automatically on every flight search. Matching offers come back tagged with a "Corporate fare" badge — no app switching, no separate booking flow.

How it works:
1. Travel → click **Corporate Rates** in the toolbar.
2. The drawer lists every saved corporate code your org has registered with Duffel.
3. Click "+ Add" to register a new code. Required fields:
• Carrier (IATA code — e.g. AA for American, UA for United, DL for Delta)
• Code (the contract identifier the airline gave you — corporate code, account number, tour code, or tracking reference, depending on the airline's program)
• Type (Corporate / Tour / Account / Tracking — picks the right Duffel field)
• Optional label and notes for your team's reference
4. Save. The next flight search you run includes the code in the offer request.

Spotting a corporate fare in results:
On the FlightCard, an accent-colored "Corporate fare" badge with a star icon appears next to the airline name when Duffel returned the offer via your registered code. Hover the badge for the matching tracking reference / account number.

Where to get the codes:
Most large airlines run "PassPlus" / "Easy Biz" / "OnBusiness" / "Smart Choice" programs for SMB. Sign up directly on the carrier's site (often free), get an account number or contract code, and paste it into the drawer. Larger negotiated contracts (TMC-mediated) come through your travel-management agency.

Multi-airline:
Add a code per airline. Searches across multiple carriers can return both retail and corporate fares for different airlines in the same result list — sorted normally by price.

Privacy:
Corporate codes are stored on the org doc and only sent to Duffel as part of the offer request. They're not exposed publicly. Only org admins / editors can register or edit codes.
