If an EarlyBird Check-In Customer chooses to change a flight, will the EarlyBird Check-In options transfer to the new flight?
"It depends. EarlyBird Check-In is tied to the Customer’s reservation for which the EarlyBird Check-In purchase was made and will be transferred to the Customer’s new flight if he/she changes the flight at least 25 hours prior to the original flight’s scheduled departure time and so long as the change is to a flight that will depart in more than 25 hours. Since EarlyBird Check-In is associated with a reservation, any changes must be made within the same reservation record (same confirmation number) in which the Customer purchased EarlyBird Check-In."
