tychohq 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

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-stopsto 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.
