I was planning a trip from New York to London in August, and instead of opening 12 tabs comparing flights, I decided to ask ChatGPT 5.2 to do the heavy lifting.
The results were surprisingly structured and fast. It compared multiple booking platforms and highlighted the cheapest option clearly.
This prompt worked perfectly for me but you can enhance it even more by asking for flexible date optimization, baggage fee comparison, and nearby airport alternatives.
Enjoy your travels, folks
