A. 1. Review the airline's policy on flight changes before booking. If you anticipate needing to change your flight, consider purchasing a flexible fare that allows for changes at a lower cost. 2. If you need to change your flight, do so as early as possible, as fees may increase closer to the departure date.

B. 3. Check if there are any promotions or waivers for change fees, especially during certain periods or for specific routes. 4. Consider using travel insurance that covers flight changes, which may help mitigate costs.
