Endpoint
POSThttps://stabletravel.dev/api/flights/upsellWhen to prefer
Use this endpoint when you already have a flight offer or order and want to present the traveler with upgrade or add-on options before or after booking. Prefer this over a fresh flight search when you need upsell-specific offers tied to an existing itinerary rather than new flight options.
Side effects
- Invalid or expired flight offer/order ID returns 400 or 404
- No upsell offers available for the given flight returns empty offers array
- Malformed request body returns 400 Bad Request
- Authentication or payment failure returns 401/402
- Amadeus upstream service unavailable returns 503
