Compare flight options before you book

They used ChatGPT to research flights, then checked other tools because it could not access live fares or complete the purchase.

What they did
A user asked ChatGPT to look up flights between Shanghai and Tokyo and return a side-by-side list with flight numbers, departure times, prices, baggage rules, and the cheapest choice. ChatGPT produced a route summary, but it also made clear that it could not read real-time fare data. The user then turned to Manus for airline-site lookup and Sheet0 for automatic extraction into a spreadsheet, compared the outputs, and finished the booking outside those tools.
How it went
No single agent carried the task from search through checkout. ChatGPT was useful for narrowing options, Manus could collect data from airline pages, and Sheet0 produced an organized sheet. In comments, the user said Gemini with Google Flights felt more trustworthy, although it returned many fewer results than ChatGPT and Sheet0.
Tips
Treat ChatGPT as a planning layer, not the final price source, when live fares matter. For travel bookings, build in a stop for review before any payment or submission step.

Try it yourself with ChatGPT

Act as a flight comparison helper. Search for flights from [origin] to [destination] for [date or date range], with [number] or fewer stops and any other limits I specify. Show the top [3] choices from at least [3] sources, including flight number, departure time, total cost with bags, and the cheapest option. If you cannot see live prices, say that clearly and still organize the results you can gather. Do not book anything; pause and ask for my approval before any payment, passenger-details entry, or final submission.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
