ChatGPT for Trip Planning: The Effect of Narrowing Down Options

ChatGPT is expected to have significant implications for trip planning from a traveler’s perspective. ChatGPT has the potential to be a revolutionary search tool, enabling travelers to bypass an often complicated and disturbing process with a simple conversation with ChatGPT. This research aimed to explain the impact of ChatGPT on travelers’ trip planning behavior; specifically, it examined how travelers perceive ChatGPT when they narrow down multiple travel options. Based on the choice overload effect, we conducted five experimental studies to determine the negative effect of reducing options from the initial recommendations using ChatGPT. The results showed the importance of a hybrid decision-making process involving both humans and ChatGPT. Using our empirical results, we provide significant theoretical and practical implications for travelers’ trip planning behavior incorporating ChatGPT.
