Google Flights API: flight prices, cheapest dates and full itineraries

Get flight prices from Google Flights for any route and date, in bulk. One way or round trip, any cabin, any number of passengers, nonstop or with stops, only the airlines you want. Every flight comes with its price, airlines, flight numbers, departure and arrival times, duration, layovers, aircraft, legroom and CO2 emissions. Switch to cheapest dates to get Google's price calendar: the lowest fare for every departure date over the next weeks or months.

No login, no API key, no browser. $1 per 1,000 flights, $0.50 per 1,000 calendar dates, and searches that find nothing cost nothing.

What you can use it for

• Fare tracking and alerts: schedule a run every day for the routes you care about and get the price change the moment it happens.
• Cheapest day to fly: price every departure date for the next 2 to 11 months in one run, for one-way or round trips of a fixed length.
• Travel apps, deal newsletters and AI agents: clean JSON with every leg, ready for your own search, alerts or chat assistant.
• Airline and route research: who flies a route, how often, how long it takes, nonstop or not, and at what price.
• Corporate travel and budgets: what a trip really costs in business vs economy, for a team, on given dates.

How to use it

1. Put one route per line in Routes: airport codes (LHR-JFK), metro codes for every airport in a city (LON-NYC, PAR-TYO, CHI-WAS), city names (London-New York), or several airports on one side (SFO,OAK-LAX).
2. Set the departure date. Add a return date for a round trip.
3. Optional: cabin, passengers, stops, airlines, maximum price, order.
4. Optional: Departure dates to cover repeats every route for that many consecutive days (a round trip keeps its length).
5. Run it and download the results as JSON, CSV or Excel, or read them through the API.

For the cheapest date, set What to get to Cheapest dates (price calendar) and Days in the price calendar to how far ahead you want to look.

Tips

• Use metro codes or city names to cover every airport in a city at once: LON covers Heathrow, Gatwick, City, Stansted and Luton.
• Round trips are priced as Google prices them: the round-trip total, shown next to each outbound flight.
• maxStops, airlines and maxPrice are applied by Google itself, so results match what you see on the site with the same filters.
• Schedule the Actor in Apify (daily or hourly) and connect the dataset to Google Sheets, Make, Zapier or your own API for fare alerts.
• Results are what Google shows a US searcher by default; set country and currency for another market.

FAQ

Is it legal? It reads public Google Flights results that anyone can open without logging in. You are responsible for how you use the data.

Why does a search return fewer flights than I asked for? Google lists a limited number of options per route and date, usually 10 to 60. Nonstop-only or airline filters shrink that further.

Can I book through it? No. It returns prices and itineraries; googleFlightsUrl opens the same search on Google Flights, where you can pick the flight and booking site.

Do I get return flights for a round trip? Each row shows the outbound itinerary with the round-trip price, the way Google lists round trips first. Run the return direction as its own route if you need the return legs too.

Something broke or you need a field? Open an issue on the Actor's Issues tab and it will be looked at quickly.
