Who hasn’t looked into advertisements boasting flights starting at $59? During slower seasons, offering lower fares allows airlines to maintain profits by selling seats that might otherwise be empty. According to an analyst at Hudson Crossing, 1 out of 10 people will book an unplanned flight because of good travel deals. However, these deals are typically accompanied with a number of restrictions, such as no refunds, flights that leave only on specific days, and limited destinations. For these reasons, airlines don’t actually expect to sell many tickets at these prices.
