Carnival Cruise name change policy allows modifications on most bookings, though rules vary by fare type. Standard fares without Carnival-arranged airfare usually permit changes without fees. Bookings with Fly2Fun Flexible Air may incur penalties or a $200 service charge if changed within restricted periods. Fly2Fun Restricted Air requires purchasing a new ticket. Restricted or promotional fares may not allow changes. Name changes must retain the original guest; otherwise, cancellation fees apply. For assistance, contact TFN 1-808-900-8120 (OTA).
