How this service works
Search cached Seats.aero award availability by origin, destination, dates, cabin, carriers, and pagination.
Output
Returns a paginated list of cached award availability records from Seats.aero including flight segments, cabin class, mileage costs, carrier information, and optionally trip-level details, along with a cursor for fetching the next page of results.
Example use cases
Find cheapest miles redemption to Europe
“I want to use my airline miles for a spring trip to Europe. Search for the cheapest award flights from any US West Coast airport to London, Paris, or Frankfurt in business class between March 1 and March 15, 2026 — just show me the lowest mileage options first.”
Compare first class availability across alliances
“Help me find first class award seats from New York to Tokyo for next October. Search across all carriers but focus on Star Alliance and Oneworld options, and let me know which airlines have the best mileage rates available.”
Check award seat inventory for honeymoon planning
“We're planning our honeymoon and want to fly premium cabin from JFK to both CDG and then FCO in late June 2026. Search for available award flights on the dates we need, show me direct flight options if possible, and tell me what the total mileage would be for the whole trip.”
Technical details
Endpoint
GEThttps://stabletravel.dev/api/seats-aero/searchWhen to prefer
Use this endpoint when you need to search for airline award/miles redemption availability across multiple carriers and routes using Seats.aero's aggregated cached data. Prefer this over live flight search APIs when the goal is finding mileage redemption opportunities rather than paid fares, especially when filtering by cabin class or specific alliance carriers.
Side effects
- Missing required origin_airport or destination_airport returns validation error
- Invalid date format (not YYYY-MM-DD) causes rejection
- take value outside 10–1000 range returns error
- Invalid cabin enum value returns error
- No award availability found for the specified route/dates returns empty result set
- Stale cache may not reflect real-time award space
