Google Flights Fare Calendar: Cheapest Fare for Every Day
Pricing
$0.01 / 1,000 calendar days
Google Flights' date grid as data: the cheapest fare for every departure day over up to 180 days per route, one way or round trip, any currency and market, with a cheapest-day flag and a link per day. Up to 100 routes per run. Trial: 0.01 USD per 1,000 days until 30 Nov 2026.
Enter 1-100 routes using uppercase three-letter airport codes, such as JFK-CDG. Requires airport codes, not city codes: use JFK instead of NYC. Spaces and duplicate routes are removed.
[ "JFK-CDG"]YYYY-MM-DD or a relative date such as 3 weeks. Empty means 14 days from today. Relative dates count from the run date (UTC). The whole window, including returns, must stay within 330 days ahead.
Cover 1-180 consecutive departure dates per route, starting at startDate. One Google request per route. Free plans return at most 60 calendar rows across the run. Cheapest-day flags are calculated over the full requested window before that cap.
0 for one way; 1-30 for a round trip returning this many days after each departure. Round-trip prices cover the entire trip.
Number of adults, from 1 to 9. Prices cover the whole party.
Number of children, from 0 to 8. Child passenger request codes are unverified; Google may ignore them.
