When is the best time to buy flights

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.

Planning horizon

For domestic flights the low prices are most often 1-2 months before departure, for international ones 2-4 months before. A week before departure mostly expensive last-minute fares remain.

Day of the week

Midweek departures (Tuesday, Wednesday) are usually cheaper than Friday and Sunday ones. Buying on a weekday is often better value, although the price difference depends more on the departure date than the purchase date.

Seasonality

In peak season (summer, New Year holidays, school breaks) prices are at their highest. If your dates are flexible, choose the shoulder season - the savings can be substantial.

Watch the price

It is better not to delay a good price you have found - low fares disappear quickly. AviaSeek shows current prices for each route and date.
