Travel expenses refer to the costs incurred while traveling, such as transportation, accommodations, meals, and other miscellaneous expenses. These may include fees for using airport facilities or parking, taxi fares, rental car charges, gasoline costs, hotel bills, restaurant tabs, souvenirs, and any other expenditures made during the trip. Travelers often seek to minimize their travel expenses by finding affordable transportation options, booking discounted accommodations or using reward points, eating at budget-friendly restaurants, and avoiding unnecessary purchases while on vacation.
