Tools

get_next_best_itinerary

ChatGPT

Retrieves flight itineraries from an existing itinerary search. The initial call (when no prior results exist) returns 1–4 top results. Each subsequent call iteratively returns the next best available itinerary option(s) based on the requested feature improvement(s), refining results across calls and surfacing strong alternatives when tradeoffs are required. Use the relevant current itinerary's position (as shown in the UI list) when requesting improvements.

start_itinerary_search

ChatGPT

Starts a search for live flight prices when the user wants to find, book, search, compare, or check flights. Ask clarifying questions only if info is ambiguous (e.g., user gave date range(s), unclear one-way vs round-trip). Do not delay for preferences or confirmation; default to economy cabin unless specified otherwise and infer the traveller persona from knowledge about the user. Normalize dates safely (never past dates; infer the next future year if missing). Include time preferences only when explicitly stated. Flights only; do not use for lodging or ground/sea transportation. Use get_next_best_itinerary immediately after calling start_itinerary_search to retrieve itinerary options. Call no more than once per turn.
