🟢search_empty_legs(origin, destination, date_from, date_to, passengers, ...)
Find current empty-leg flights. Give at least origin or destination (city name or IATA/ICAO code). Returns up to 20 offers with route, date, aircraft, seats, indicative price and a voidjet link plus a pre-filled inquiry link for the user. Provider names are not included. With no match, charter_alternative may offer a regular charter via partner Villiers: NOT an empty leg and a paid partner offer, tell the user both.
