during her maiden season in summer 2021 and visited ports including
Ibiza.
Costa Firenze had her debut postponed from 2020 to 2021 after Costa was forced to revise the ship's inaugural plans on numerous occasions as a result of the pandemic-induced delivery delay and operational challenges. Costa first announced on 6 May 2019 that the ship would initially spend her first month sailing in the
Mediterranean and call at ports in Italy, Spain, and France. Her original maiden voyage was scheduled for 1 October 2020, departing from
Trieste and calling at
Bari,
Barcelona, and
Marseille, before arriving in
Savona. Then, she was to depart from Savona on 2 November to begin a 51-day cruise to
Hong Kong, arriving on 22 December. But in August 2019, Costa cancelled her maiden voyage and first month of sailings in favor of repositioning the vessel to
Singapore immediately following her delivery, after which she would debut in the Chinese market on 20 October 2020. In July 2020, it was reported that Costa had considered reverting her Asia deployment plans to reschedule her for weekly Mediterranean sailings previously arranged for
Costa Toscana due to the latter's delayed delivery. In September, Costa announced a new seven-day maiden voyage in the Mediterranean commencing on 27 December. Then, in October, Costa further delayed the ship's debut in the Mediterranean with a new maiden voyage set for 28 February 2021, which was later annulled by cancellations announced in January 2021. After repeated delays,
Costa Firenze sailed on her inaugural voyage on 4 July 2021 on an all-Italian itinerary that called at
Savona,
Civitavecchia,
Palermo,
Naples,
Messina, and
Cagliari; she also began calling at ports in Spain and France in September 2021. She then followed her summer debut season with her maiden circuit in the
Persian Gulf, where she operated week-long voyages from
Dubai between December 2021 and March 2022. She returned to the Mediterranean in April 2022, where she operated week-long sailings through to November, which were followed by a repositioning to
Brazil for her maiden
South America season, where she operated until April 2023.
Costa Firenze operated her last summer with Costa through a
Northern Europe deployment between May and September 2023 and sailed her final winter season for the cruise line, calling at ports in the Mediterranean,
Atlantic Europe, and
Macaronesia prior to leaving the fleet in February 2024. == Carnival Cruise Line (2024–present) ==
