Guide

A SerpApi google_flights alternative

Published September 5, 2026

Short answer: FlightPowers' google-flights-live-api.p.rapidapi.com returns the same live Google Flights data as SerpApi's google_flights engine, plus Google's own price band (price_insights_low, price_insights_high, a low/typical/high verdict) on every result and a paired POST /v1/flights/roundtrip endpoint. Switching pays off when flights are the workload, not one engine among several you already call through SerpApi.

People land on this question from one of two places. Either the search quota is the problem, or the flight engine is one small part of a platform they are paying for and they want the flight part cheaper. Those are different problems and only one of them is solved by switching.

What SerpApi charges

Read from serpapi.com/pricing on 2026-09-05, quoted rather than paraphrased. Believe their page over this one if the two ever disagree.

PlanPriceSearches per month
Free$0250
Starter$251,000
Developer$755,000
Production$15015,000
Big Data$27530,000

Their searches are a shared pool across engines, so a google_flights call and a google_hotels call draw on the same balance. Their hotels engine was still shipped and still had no separate price on that date.

Our own plans render live on the pricing page and are never restated in a guide, because guides go stale and pricing pages do not.

What the request looks like here

One POST, JSON in and JSON out.

curl -X POST "https://google-flights-live-api.p.rapidapi.com/api/google_flights/oneway/v1" \
  -H "Content-Type: application/json" \
  -H "x-rapidapi-host: google-flights-live-api.p.rapidapi.com" \
  -H "x-rapidapi-key: $RAPIDAPI_KEY" \
  -d '{"from_airport":"LHR","to_airport":"BCN","departure_date":"2026-11-18","limit":2}'

Two differences are structural rather than cosmetic, and they are the ones that change your code.

Round trips are one request. POST /v1/flights/roundtrip takes both dates and returns itineraries with the outbound and the return already paired, a combined total_price and one buy_link for the pair. The fan-out that prices a return leg for each outbound candidate happens inside the call and bills as a single request. Details and a captured run are in round-trip prices in one request.

The price band rides on every result. price_insights_low, price_insights_high and a low / typical / high verdict come back with the fares, so a tracker has context on its first call instead of after six weeks of polling. That is the whole argument in is this flight price good.

When you should not switch

Being straight about this, because half the people reading are in this half.

SerpApi is a general-purpose Google scraping platform and we are a flights and hotels specialist. If google_flights is one engine among several you call, moving flights out means running two vendors, two keys and two failure modes to save on one line item. That is often a bad trade.

The row-by-row version, including the things SerpApi does that we do not, is on the full comparison. We keep the losing rows on that page on purpose. A comparison you cannot trust downward is not worth trusting upward either.

If you do switch

Move one workload, not all of them. Point your flight search at the free plan, run your real queries through it for a week, and diff the fares against what you were getting. Ten requests is enough to check a route you know well, a route you know badly, and a date far enough out that the price band comes back null, which is the case most people forget to handle.
