departure_idstringrequired
Parameter defines the departure airport code or city location kgmid. An airport code is an uppercase 3-letter code. You can search for it on Google Flights or IATA. For example, `CDG` is Paris Charles de Gaulle Airport and `AUS` is Austin-Bergstrom International Airport. A location kgmid is a string that starts with `/m/` or `/g/`. You can search for a location on Wikidata and use its "Freebase ID" as the location kgmid. For example, `/m/0vzm` is the location kgmid for Austin, TX. You can specify multiple departure airports by separating them with a comma. For example, `CDG,ORY,/m/04jpl`.
