ChatGPT Prompts: Travel Price Hunt Before Booking
Challenge
Global prices spin faster than a baggage carousel. Airfares can change 30 times a day, hotel rates shift with every conference, and car-rental algorithms now mimic stock-trading bots. What looks like a steal at sunrise feels scandalous by sundown. Yet with the right intel (and two fingers poised over “Track price”) you can pin those numbers down.

Dynamic pricing: airlines, OTAs and even restaurants scrape your cookies for willingness to pay.
Currency quirks: spot movements can swing a five-night stay by the cost of an aperitivo flight.
