Google Flights Toolkit
Arcade's Google Flights toolkit lets LLMs search and resolve flight itineraries via the SerpApi Google Flights API, covering one-way, round-trip, multi-city, and booking-option lookups.
Capabilities
- Airport lookup — Resolve city names, country names, or airport names to IATA codes, including metropolitan area codes (NYC, LON, etc.) usable across all search tools.
- One-way & round-trip search — Search Google Flights for outbound-only or return itineraries in a single call; results include direct
google_flights_urlbooking links andbooking_tokenvalues for downstream vendor lookups. - Multi-city / open-jaw search — Query bundled multi-leg itineraries that are typically cheaper than equivalent summed one-ways; results also carry direct
google_flights_urllinks. - Booking-option resolution — Decode a
booking_tokenfrom any search result to enumerate the airlines and OTAs selling that exact itinerary, with optional POST data for backend vendor hand-offs.
Secrets
SERP_API_KEY — A SerpApi API key used to authenticate all Google Flights requests. Obtain it by creating a free or paid account at SerpApi, then navigating to your dashboard where your private API key is displayed. No special scopes or plan are required to access the Google Flights engine, though higher request volumes require a paid plan. Provide this key as a secret in your Arcade configuration.

|---|---|---|---|
Resolve a ``booking_token`` to the airlines and OTAs selling that itinerary.
Pass a ``booking_token`` from a one-way, round-trip, or multi-city
flight search result to get the vendors selling that specific
flight. The token encodes the route, dates, cabin class,
and passenger counts (every segment for multi-city), so there are
no ``travel_class``, ``num_adults``, or ``num_children`` parameters;
supplying a cabin or party size would silently disagree with the
itinerary the token was issued for.
Leave ``include_booking_post_data`` off (the default) when an LLM
is comparing prices; turn it on only when a backend needs to
rebuild the vendor hand-off, since the POST body is multiple
kilobytes per option. | 1 | ||
Find IATA airport codes for a city, country, or airport name.
Metropolitan codes (NYC, LON, TYO, PAR, ...) are accepted as a
``departure_airport_code`` or ``arrival_airport_code`` in flight
searches and mean "any airport in this city". | |||
Search Google Flights for one-way or round-trip itineraries.
For a trip where the traveler returns to their origin, issue a
single call with both ``outbound_date`` and ``return_date`` set.
Do NOT issue two separate one-way searches in opposite directions
and sum the prices: airlines price round-trip fares independently
from one-way fares, so the sum of two cheapest one-ways is rarely
equal to the cheapest round-trip and is typically more expensive.
Each returned itinerary carries a ``google_flights_url`` that opens
that specific pre-selected flight on Google Flights, so you can hand
the user a booking link straight from these results without a
separate booking-options lookup. | 1 | ||
Search Google Flights for a multi-city (open-jaw) itinerary.
Use this for trips that are neither a simple one-way nor a round-trip
(e.g. an open-jaw three-leg trip that ends back at the origin).
The open-jaw bundle is typically cheaper than the equivalent set
of one-way searches summed; never substitute several one-way
searches for a single multi-city query.
Each returned itinerary carries a ``google_flights_url`` that opens
that specific pre-selected itinerary on Google Flights, so you can
hand the user a booking link straight from these results without a
separate booking-options lookup. | 1 |
