Whether you can change your Expedia flight without a fee depends on various factors, including the airline's policies, the type of ticket you purchased, and any specific terms outlined in your booking. Expedia acts as a third-party intermediary, facilitating bookings between travelers and airlines. While Expedia itself may not charge a change fee, the airline you're flying with might have its own policies regarding changes and fees. Some airlines offer flexible booking options or allow changes without fees under certain circumstances, while others may charge a fee for any modifications to your itinerary. It's essential to review the terms and conditions of your booking, including the fare rules and any applicable fees, before attempting to change your Expedia flight. Additionally, contacting Expedia's customer service team or the airline directly can provide further clarity on your options for making changes to your flight reservation.
