LLMs produce unreliable, hallucinated travel itineraries that waste time and money

Travelers attempting to use LLMs for trip planning receive confidently-stated but factually incorrect information about destinations, accommodations, transportation, and logistics. Current LLM solutions lack real-time data, local knowledge verification, and accountability, forcing users to manually fact-check every recommendation or abandon the tool entirely. This creates frustration because while LLMs promise to save planning time, they actually introduce risk and require extensive validation work.
