Can you cancel and rebook a flight within 24 hours?

Although airlines must hold a reservation for 24 hours or provide a refund to consumers at their request within 24 hours of making a reservation, airlines are not required to make changes to a ticket free of charge (for example - change your ticket to a different date or correct a misspelled name on the reservation).
