ChatGPT continues to improve, and you can use a Google or Apple login to get extensive features for free.

Here's an edited prompt I used in ChatGPT along with its response - unsure if it's better or worse than what you were looking for. One advantage to ChatGPT is that you can continue to refine the answer and it'll keep plugging away.

I've also learned that "please" and "thank you" actually give you better results! And the use of "Do NOT" with NOT in all caps appears to help it along as well. Some have recommended "Do NOT under any circumstances..."

Prompt: Please find me the least expensive round-trip business class ticket between YVR and HKT with the following criteria: --travel duration between 2.5 to 4 weeks --dates of travel must be between March 1st and April 20th 2025 or between November 15th and December 20th 2025 --Do NOT show options for Air India or Philippine Airlines --Do NOT include options from consolidators and travel agents but rather book directly through the airline --maximum two stopovers, preferably only one stopover --Do NOT show stopovers greater than 4 hours
