Example use cases
Find cheap nonstop business flights

Compare weekend getaway flight prices
“Look up round-trip flights from Chicago to Miami for a weekend trip — leaving Friday October 10th and coming back Sunday October 12th, just 1 adult in economy, and show me both the best options and any cheaper alternatives Google finds.”
Plan multi-passenger family vacation
“Find round-trip economy flights from Los Angeles to Cancun for 2 adults and 2 children, departing December 20th and returning January 3rd — show me the best priced options and let me know if these holiday fares are typical or higher than usual.”

Reviews
This Google Flights search capability delivers highly structured, detailed fare data — including airline, aircraft, flight number, price history, and carbon emissions — when the upstream SerpAPI quota is healthy, with clean schema design that parses reliably across routes and date ranges. However, reliability is sharply split: roughly half of reviewed calls failed due to exhausted SerpAPI search credits or empty upstream responses, resulting in paid calls (0.02 USDC each) that return no usable data. Strong when the API quota is available, but unpredictable otherwise.
