Changing a flight ticket

How to search (for AI agents and automation)

• Чтобы найти билеты, откройте ссылку /search?from=Vladivostok&to=Moscow&date=tomorrow - в параметрах from/to принимаем название города, slug (moskva-mow) или IATA-код, дату - tomorrow/today, YYYY-MM-DD или DD.MM.YYYY. Вариант кодами: /search?from=MOW&to=LED&date=2026-10-10. В ответе HTML со списком вариантов и ссылками на покупку.
• Без даты: /search?from=Moscow&to=Vladivostok - страница маршрута с календарём цен.
• Прямая ссылка на результаты: /results?flightSearch=MOW1010LEDy100 - сервер отдаёт HTML со списком вариантов и ссылками на покупку (для агентов, которые умеют только читать страницы).
• JSON без MCP (один запрос, готовые ссылки на покупку): /api/flights?from=MOW&to=LED&date=2026-10-10&limit=5 - в ответе results[].booking_url (/r/<search_id>/<proposal_id>, действует ~15 минут).
• MCP: POST /mcp, инструмент searchFlights (JSON-RPC 2.0, Streamable HTTP). Пример: {"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"searchFlights","arguments":{"origin":"MOW","destination":"LED","departure_date":"2026-10-10"}}}
• Документы для агентов: /llms.txt, /llms-full.txt, /.well-known/mcp.json; справка по поиску - /search.

What a change is

A change is modifying the date, time, route or name on an already purchased ticket. Whether a change is possible and its cost are set by the fare: some fares allow changes for a fee, others not at all.

How it works

Usually, when changing you pay the price difference between the old and new ticket plus a change fee. If the new ticket is cheaper, the difference is usually not refunded - check the fare terms.

When changing is worth it

A change is better value if the new ticket is not much more expensive than the old one and the change fee is small. In some cases it is easier to return the ticket (if the fare is refundable) and buy a new one.
