Prompt Improved prompt

Improved prompt: strengthened by us to avoid the problem in the source. Not tested by the poster. It doesn't change what happened in the source.

Not sure how to start? Tell me what you're trying to get done and I'll help you turn it into a clear request.

Goal: Plan a 6-week trip through Southeast Asia with real flights I can book.

Quick check first: Which countries, which dates, and roughly what budget?

What I need from you:
- Start and end dates ([DATES]) and where you're flying from
- Countries or cities you want to include
- Budget and travel style

Rules:
- Only list flights you have found on the airline's website or a booking site for my dates, with the flight number.
- If you can't confirm a flight, write 'not confirmed' and suggest searching that route yourself. Never invent a flight.
- Plan the route so it doesn't double back, and include time for overland legs.
- Give me a link for every flight and place you mention.
- Don't book anything.

Output: A day-by-day route, a flight table (route, airline, flight number, date, price, link, confirmed yes/no), and where to stay in each stop.

If any of this is unclear, tell me what you have and I'll help fill the gaps.

You'll know it worked when: every flight in the plan opens on a real booking page for your dates.
