Google Flights Cheapest Fare Monitor

Track the cheapest public Google Flights fare for any route and date. One clean row per check, built for schedules. Failed or empty runs are free.

What you get

Give it an origin, a destination and a date. By default it returns one row: the cheapest fare shown on the first Google Flights results screen, with airline, stops, duration, departure and arrival time, and Google's price level (low / typical / high). Put it on a schedule and you have a simple fare watcher.

Need more than the cheapest? Set cheapestOnly to false and raise maxResults (up to 150) to get one row per offer.

You pay only for rows that carry a price. Blocked pages, empty results and unpriced offers cost nothing.

What it is

• A reader for the public first results screen of google.com/travel/flights (server-rendered HTML, no login, no browser, no proxy).
• One dataset row per fare offer; in the default mode, one row per route/date (the lowest price).
• Price, currency, airline, stops, total duration, local depart/arrive time, price level, and a link back to the same Google search.

What it isn't (honest limits)

• Not the full result list. It reads what the first screen shows (often 10–30 offers), not every flight Google can find.
• Not the Date grid / Price graph calendar. Those are drawn in the browser and are not in the public HTML. calendarDays > 0 only writes a free notice row today.
• No flight numbers or airline IATA codes when the first screen does not show them (fields stay empty; nothing is guessed).
• No booking, no booking-site offers, no seat maps, no personal data.
• Results depend on what Google returns to the run's IP; sometimes the page has no offer cards. Those runs write a free notice row and are not charged.
