Google Flights Scraper - Date Range & Price Drop Monitor

Get Google Flights prices and flights for a route across a range of departure dates in one run, as clean JSON: every flight Google Flights lists, with price, airline, flight numbers, local departure and arrival time, duration, stops, layovers, aircraft, legroom and CO2. Turn on Monitor and scheduled runs return only new flights and price changes (with the previous price), so a fare alert, travel deal site or pricing dashboard does not re-download and pay for the same flights every hour.

• Date range in one run. Search every departure date from departureDate to departureDateTo (up to 31 dates). For round trips the length of stay is kept: departing a day later returns a day later.
• Price drop monitor. onlyChanges returns flights that are new or whose price moved since the last run of the same search, with previousPrice, priceChange and priceChangePercent. Moves under 1% (exchange-rate noise) are not returned unless they add up.
• What Google Flights shows, nothing guessed. Prices are the totals Google Flights shows for all travelers, in the currency you choose; the row carries the currency Google actually answered in.
• No charge when Google Flights cannot be read. Dates that could not be read come back as free rows that say why. A run where no date could be read is not charged at all.
• Fast. One departure date is one Google Flights page: production runs on 2026-09-24 took 2.9-4.3 s for one date and 6.8-9.8 s for 5-7 dates, at 256 MB.

Checked against the Google Flights page in a browser right after the run: 5 of 5 flights had the same departure and arrival time, airline, price and CO2 on screen (12:26 PM – 9:59 PM Frontier ... 225 kg CO2e +9% emissions ... $139). The same check on a round trip in EUR: 5 of 5 (€495 round trip).

Column	Meaning
status	ok for a flight row. Other values are free rows that say why nothing was returned (below).
changeType	first-check (first run of this search), new (not seen by this watch on this date before), price-down, price-up or unchanged (also used for a flight seen before but never returned)
departureDate, returnDate	The searched dates. returnDate is null for one way
origin, destination	Airports of this flight (with several airports per side, the one this flight uses)
price, currency	Total price for all travelers as Google Flights shows it, and the currency Google answered in
priceScope	one-way, or round-trip-total (Google Flights shows outbound flights with the round-trip total before a return flight is picked; return flights are not listed)
travelers	Number of travelers the price is for
previousPrice, priceChange, priceChangePercent, previousCheckedAt	The price at which this watch last returned this flight on this date, the difference, and when that was. Null on a first check, a new flight, or a flight this watch has seen but never returned
priceRankOnDate, cheapestPriceOnDate, isCheapestOnDate, flightsFoundOnDate	Where this flight stands among all flights Google Flights listed for that date
airlines, flightNumbers	Airline names and flight numbers of all segments
departureLocal, arrivalLocal	Local date and time at the departure and arrival airport (no time zone, as shown on Google Flights)
durationMinutes, stops, layovers	Total travel time, number of stops, and each layover's airport, city and minutes
legs	Each flight segment: flight number, airline, airports, times, duration, aircraft, legroom
co2Kg, typicalCo2Kg	Estimated CO2 of this flight and the typical CO2 for the route, as Google Flights shows them
googleSection	top (Google's "Top flights") or other
cabinClass	The searched cabin class
googleFlightsUrl	The same search on Google Flights
note, search	Free rows only: why nothing (or not everything) was returned, and the search in words
watchName, checkedAt	The watch name you gave, and the time of the check

Free rows (not charged)

status	When
no-flights	Google Flights shows no flights for this route on this date (or none at or under maxPrice)
no-change	Monitor on: no new flight and no price move on this date since the last run
more-not-returned	More flights than maxFlightsPerDate; says how many were left out (not charged)
bad-input	The input could not be used, or Google Flights did not accept it (unknown airport code, a date in the past or more than about 330 days ahead)
unreadable	Google Flights could not be read for this date, even after asking again from other IP addresses
blocked	Google showed a check page. This Actor does not solve or bypass check pages; it stops and does not search the remaining dates
budget-reached	The run hit the maximum total charge you set. Rows not returned are not remembered, so the next monitor run returns them

How monitoring works

The Actor remembers, per search and watchName, which flights it has seen on each departure date and the price at which it last returned each one (in a named key-value store in your account). On the next run it compares: a flight it never saw on that date (or that was above maxPrice last time and is now under it) is new; a flight whose price moved by at least minPriceChangePercent from the price it was last returned at is price-down or price-up. Flights it saw but never returned (beyond maxFlightsPerDate on the first run) and flights above maxPrice do not change the remembered price, so you are never sold the same price twice. With onlyChanges on, only new and moved flights are returned and charged; a date with nothing to report comes back as one free no-change row. The run start fee is still charged on a run with no changes (it pays for the check): an hourly watch with no changes costs 720 start fees a month. With a +N date range, each day one new departure date enters the window and its flights are returned once as first-check. Google Flights sometimes lists a flight in one search and not in the next; such a flight is reported as new once and compared by price after that. Two runs of the same search and watch name at the same moment can overwrite each other's memory, so do not overlap schedules of one watch.

Pricing

Pay per event: a small start fee per run that read at least one flight, plus a fee per flight row returned. Free rows are never charged. A run where no date could be read, or where Google Flights showed no flights, charges nothing. If your maximum total charge for a run has no room for the start fee plus one flight, the run requests nothing and charges nothing.

Limits

• Prices change all the time; a row is what Google Flights showed at checkedAt. The final price is on the airline or agency site.
• Infants are not supported: with infants, Google Flights lists only some flights or none (for example 0 of 36, or 4 of 13), so such searches are refused with a free bad-input row.
• Round trips list outbound flights with the round-trip total; return flights are not listed.
• One route per run (several airports per side are fine). Up to 31 departure dates per run.
• Google may show a check page to automated traffic; the Actor does not bypass it and returns a free blocked row instead.
