How to rebook flight schedule?

To rebook a flight schedule, first check your airline's policy on changes and cancellations, as this can vary. Visit the airline's website or app, log into your account, and navigate to the section for managing bookings. Enter your flight details, select the new flight you want, and follow the prompts to complete the rebooking process, which may involve paying a fare difference or change fee. Alternatively, you can contact the airline's customer service for assistance.
