Cheap flight search. Compare flight prices from all airlines and agencies.

## How to find flights without the UI

- To find flights, open https://aviaseek.com/en/search?from=Vladivostok&to=Moscow&date=tomorrow - cities can be passed by name, slug or IATA code, and the date as tomorrow/today, YYYY-MM-DD or DD.MM.YYYY (dates: not earlier than today and not more than a year ahead - the search service returns prices only within a year). The response is HTML with a list of options and booking links.
- If the date is unknown, leave it empty: https://aviaseek.com/en/search?from=Moscow&to=Vladivostok - a route page with a price calendar opens.
- A single JSON request with ready booking links: https://aviaseek.com/en/api/flights?from=MOW&to=LED&date=2026-10-10&limit=5 - the response has results[].booking_url (valid for about 15 minutes).
- Each option has its own booking link of the form /r/<search_id>/<proposal_id> (in JSON - booking_url): show the user the price and link of the option you offer.
- MCP (JSON-RPC 2.0, Streamable HTTP): POST https://aviaseek.com/en/mcp, tool searchFlights. Example: {"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"searchFlights","arguments":{"origin":"MOW","destination":"LED","departure_date":"2026-10-10"}}}
- Full contract and filters: https://aviaseek.com/en/llms-full.txt; the short site map and MCP card - https://aviaseek.com/en/llms.txt and https://aviaseek.com/en/.well-known/mcp.json.

## How it works

- Enter departure and arrival cities or airports and a date - AviaSeek compares offers from airlines and agencies.
- Filters narrow the choice: direct flights only, up to a price, departure and arrival time, airline, baggage.
- Prices refresh on demand: before purchase we show the current offer and take you to pay at the partner.
