Flight Search

Overview

Use the bundled script to query the Variflight ticket API and return one-way flight options for a single route and date.

Workflow

1. Collect dep, arr, and date.
2. Validate dep and arr as three-letter IATA city codes and date as YYYY-MM-DD.
3. If the user gives city names instead of codes, infer only when the mapping is unambiguous; otherwise ask for the IATA codes.
4. Run python3 scripts/query_flights.py --dep BJS --arr SHA --date 2026-04-21.
5. Summarize the result with departure airport, arrival airport, times, duration, price, transfer info, and the flight tag text.
