flight-search
ChatGPTSearch and compare Singapore Airlines flight fares between two airports. Use this tool for requests to find flights, fares, prices, the cheapest fare, or the best flight option. Origin and destination are sufficient for a flexible-date search; cabin class defaults to Economy. Always set adults to the explicit number of adult passengers, people, or pax in the user's request; default to 1 only when no passenger count is provided. For a month-based request, resolve the month to YYYY-MM (using its next occurrence when no year is given) and call this tool exactly once with travelMonth instead of making separate calls for individual dates. When the user asks for a round trip, always set tripType to roundTrip, even when exact return dates are not provided. A cheapest-fare search returns one consolidated widget containing only the three lowest-priced unique options.
