      What this check looks for
    Description, as the server wrote it
    Use this when a traveler asks how to change, cancel or get a refund for their own flight, ferry, hotel or rental booking, check-in, a boarding pass or e-ticket, bags or seats, or a trip the company cancelled or delayed, including one bought via another site or agent. Returns which company handles it and where, dated fees, deadlines and refund rules with sources, and what the traveler does personally. These vary by company and seller and change over time. Useful before opening the site. Read-only.

      What this check looks for
    Description, as the server wrote it
    Use this when a traveler's flight was cancelled, delayed, overbooked or downgraded and they ask what they are owed or their options: compensation, a refund or care. EU261/UK261 check: verdict with the rule, amount, what the airline owes now, facts that would change it, where the traveler claims (airline, then national enforcement body), evidence. Flights only, not ferries. Dated official sources; stores nothing about the traveler and submits nothing. Not legal advice.

    Why it is in this group

    • The name "find_official_booking_site" says "find": a word for reading.
    Description, as the server wrote it
    Use this when a traveler asks how or where to book with a named airline, ferry, hotel, vehicle-rental or booking company. Returns its official site and booking page and, where listed, its own booking channels (app, API, MCP), dated rules with sources and what the traveler does personally. Flags sites not on the company's listed domains. It does not search fares or availability, or book.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
