An AI-powered itinerary planner that generates, validates, and optimizes complete travel plans based on user preferences, dates, group composition, and budget. It cross-references real flight/ferry/train schedules, hotel pricing, visa/pet-import requirements, and crowd-sourced traveler data to flag pacing issues, suggest accommodation splits, and estimate realistic daily spend. Includes specialized modules for edge cases like infant travel, pet relocation, and multi-base trips.

Post-pandemic travel demand has surged while travel agents have largely disappeared, and LLMs now make personalized itinerary validation at scale finally feasible. Travelers increasingly turn to AI tools but current offerings (ChatGPT, Google) lack real-time logistics data and validation.
