Flights — Airfare Search via Travelpayouts/Aviasales

Prerequisites

Environment variable TRAVELPAYOUTS_TOKEN must be set with a valid Travelpayouts API token.

Quick Reference

Usage

1. Resolve IATA codes

If the user provides a city name instead of an IATA code, resolve it first:

python3 scripts/search_flights.py --lookup "Istanbul"

Pick the most relevant result's code field.

2. Search flights on a specific date

python3 scripts/search_flights.py --from MOW --to LED --date 2026-04-15 --return 2026-04-20

Add --direct for non-stop only. Add --limit N to cap results (default 10).

3. Price calendar (cheapest days in a month)

python3 scripts/search_flights.py --from MOW --to LED --month 2026-04

Returns results sorted by price. Use to recommend the cheapest travel dates.

4. Latest found prices (price monitoring)

python3 scripts/search_flights.py --from MOW --latest

Shows recently found prices from the origin to any destination. Add --to AER to filter. Add --one-way for one-way only.

5. Popular destinations from a city

python3 scripts/search_flights.py --from MOW --directions

Returns destinations sorted by price — useful for "where can I fly cheaply from X?" queries.
