The statement that is true is: customers who shop for airline tickets weeks or months in advance are likely vacation travelers and thus more sensitive to ticket prices.
This is because vacation travelers have more flexibility with their travel plans and can choose to travel on different dates to find cheaper tickets. Business travelers, on the other hand, often need to travel on specific dates and are less sensitive to ticket prices.
