By going to the airline's website and selecting Manage Booking, we may make changes to our online flight reservations. If you go to the booking section, you can alter your flight option. Then, input your reservation number. If the airline permits it, you can change your flight. To confirm your reservation, go to the website and follow the procedures. You can also alter your flight reservation by calling an airline's customer service department. Simply follow the VivaAerobus Flight Change Policy to modify your reservation.
