Use this when a traveler wants to book with a named airline, ferry, hotel, vehicle-rental or booking company, or to do something on their own booking there, such as changing or cancelling it, online check-in, a boarding pass or e-ticket, bags or seats, a refund, or which company services a booking bought elsewhere. Returns the official site and entry page, the company's own booking or service channels, which company services the booking, dated fees and rules with sources, what to have ready, and where the traveler must act personally. Also useful before opening the site in a browser. It does not search fares or availability and does not book itself. Read-only; stores nothing about the user.

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.
