Flight Search

Search real-time flight schedules and prices via Google Flights data.

Prerequisites

• Python 3.9+
• uv (recommended) — install with curl -LsSf https://astral.sh/uv/install.sh | sh

The flights-search CLI is bundled at scripts/flights-search in this skill directory.

The fast-flights library is installed automatically on first run via uvx (cached after that). Or install manually: pip install fast-flights

CLI Usage

uvx --with fast-flights python3 scripts/flights-search <origin> <destination> <date> [options]

Origin and destination accept IATA codes (JFK, LAX) or city names (NYC, London, Tokyo). City names automatically search all airports in that metro area.

Examples

# Search all NYC airports to LAX
flights-search NYC LAX 2026-03-15

# Nonstop flights from NYC to Berlin
flights-search NYC Berlin 2026-03-15 --nonstop

# Evening departures only
flights-search JFK LHR 2026-03-15 --after 17 --before 22

# Business class
flights-search NYC London 2026-03-15 --class business

# Multiple passengers with booking link
flights-search SF Tokyo 2026-04-01 --passengers 2 --link

Options

Option	Description
--nonstop	Nonstop flights only
--all-stops	Show all flights regardless of stops
--after HH	Depart after hour (24h format)
--before HH	Depart before hour (24h format)
--class	Cabin: economy, premium, business, first
--passengers N	Number of travelers (default: 1)
--link	Print Google Flights URL

Supported City Names

When you use a city name, the CLI searches all airports in that metro area:

City	Airports
NYC / New York	JFK, EWR, LGA
LA / Los Angeles	LAX, BUR, LGB, ONT, SNA
SF / San Francisco	SFO, OAK, SJC
Chicago	ORD, MDW
DC / Washington	DCA, IAD, BWI
London	LHR, LGW, STN, LTN, LCY
Paris	CDG, ORY
Tokyo	NRT, HND
Toronto	YYZ, YTZ

60+ metro areas supported. Use any IATA code directly for airports not in the list.

Default Behavior

By default, the CLI shows only flights with the minimum stops available:

• If nonstops exist → shows only nonstops
• If no nonstops → shows only 1-stop flights
• Use --all-stops to see everything

Output

Searching from NYC: JFK, EWR, LGA

Notes

• Date format: YYYY-MM-DD
• Airport codes: Standard IATA codes (JFK, LAX, LHR, etc.)
• Prices are in USD
• Times shown in local airport timezone
• No API key required — uses Google Flights data via reverse-engineered protobuf API
• Some routes may return price-only results (missing departure/arrival times) due to upstream parsing limitations

Data Source

Uses Google Flights data via the fast-flights Python package.
