Google Flights Search

Search Google Flights via agent-browser to find flight prices, schedules, and availability.

Prerequisites

Requires agent-browser CLI:

npm install -g agent-browser && agent-browser install

When to Use

• User asks to search/find/compare flights or airfare
• User wants to know flight prices between cities
• User asks about flight schedules or availability
• User wants to find the cheapest flight for specific dates
• Southwest flights: Google Flights is one of the only sources for SW cash prices. No GDS or API returns Southwest.

When NOT to Use

• Completing purchases: This skill finds flights and extracts booking links, but do not attempt to complete a purchase on a booking site.
• Hotels/rental cars: Use other tools for non-flight travel searches.
• Historical price data: Google Flights shows current prices, not historical.

Session Convention

• Economy + Business comparison (default): --session econ and --session biz
• Single cabin search: --session flights
• Interactive fallback: --session flights
