    Description, as the server wrote it
    Records a need voidjet cannot serve, for when the user wants voidjet to know about it: e.g. no offer on the route, a return flight, pets, instant booking. Takes 1-5 categories and optional route, dates, passengers and budget; no personal data. Helps voidjet decide what to add.

    Why it is in this group

    • The name "search_empty_legs" says "search": a word for reading.
    Description, as the server wrote it
    Finds current empty-leg flights by origin and/or destination (city, IATA/ICAO code, country, US state, region or area such as Greek Islands), dates, passengers, budget and aircraft class. Returns up to 20 offers with route, date, aircraft, seats, indicative price, a voidjet link and a pre-filled inquiry link; provider names are not included. When more offers match, refine summarises all matches (frequent destinations, date span, prices). With no match, charter_alternative may contain a regular charter via partner Villiers: NOT an empty leg, and a paid partner offer.

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.
