Flight Search

Search one-way flight options by departure city, destination city, and date using Ctrip mobile results, then sort by price ascending. Use when the user wants a quick flight lookup like "查一下上海到北京 2026-04-01 的机票", or asks for results that include flight number, departure/arrival time, price, and whether the itinerary has a transfer.

Use the bundled CLI to fetch and normalize Ctrip mobile flight results.

Workflow

1. Normalize the user's departure city, destination city, and date.
2. Run scripts/search_ctrip_flights.py.
3. Return the cheapest options first.
4. For each result, include at minimum:
   • flight number
   • departure time
   • arrival time
   • price
   • whether it is direct or has a transfer

Input Rules

• Accept either Chinese city names or 3-letter city/airport codes.
• Expect dates in YYYY-MM-DD format.
• Treat this as one-way search only unless the skill is explicitly extended.
• If the requested date is in the past, stop and tell the user.

Output Rules

• Sort results by price from low to high.
• Prefer concise Chinese output that reads cleanly in Telegram.
• Format each option as two short lines: flight number, then time + price + transfer status.
• Show at least 5 options when available.
• After the first 5, stop when the fare exceeds 1.5x of the cheapest shown fare, or exceeds 1000 yuan.
• Mark transfer status as 直飞 or 转机N次.
• If the script returns zero results, say that no flights were found for that route and date.
• Never invent missing prices or schedules.
