Being flexible with your travel dates can significantly impact the price of your flight. Mid-week flights or traveling during off-peak seasons often present lower fares. Even shifting your departure or return by a day or two may result in savings.

Before booking, always check for potential extra costs such as baggage fees, seat selection charges, and in-flight services. Some airlines may also charge for printing boarding passes at the airport. Factor these into your total travel budget.
