Use this skill whenever the user needs a cost estimate for a business trip — including "what will it cost to get to X", "price up that customer visit", "I need a travel budget for the offsite", or a manager asking for a number before approving travel. Prices flights and hotels live from the company's browser-based booking tool, benchmarks the non-bookable lines against the user's own approved expense reports, and produces a forwardable estimate. Do NOT use this skill to actually book, hold, or confirm travel.
