Carnival subsidiary
After Carnival's take over, a new-building program commenced for the line, utilizing Carnival Cruise Lines Spirit-class and Destiny-class design platforms for the new ships. The line would also utilize Carnival's designer Joe Farcus, who undertook the interior design, moving away from the contemporary Italian style of the previous ships to more themed public spaces similar to Carnival Cruise Line.[12] The first ship delivered under Carnival Corp management, was Costa Atlantica in 2000.
In 2000, Carnival Corporation took full control of Costa Crociere after buying out Airtours' 50% interest for $525 million.[13] Carnival Corporation would transfer older ships from their other brands to Costa, with the Costa Tropicale (former Carnival Cruise Line Tropicale) in 2001, and the Costa Europa (former Holland American Line Westerdam) in 2002.
In 2002, Carnival Corporation and P&O Princess Cruises merged to form Carnival Corporation & plc, bringing together both companies' assets under one corporation.[14] As of 2018, Costa accounted for approximately 12% of Carnival Corporation & plc's revenue.[15]
In 2004, Costa Crociere purchased control of AIDA Cruises of Germany.[16] Carnival Corporation and the Spanish tour operator Orizonia Group created a joint venture in 2007, Ibero Cruises,[17] which was absorbed into Costa Cruises in 2014.[18]
The company attracted international attention when Costa Concordia ran aground and capsized off the coast of Italy on 13 January 2012.[19] Thirty-two people died in the disaster.[19] Six weeks later, the company made headlines again when a fire on Costa Allegra left it drifting without power for 13 hours in waters near Somalia frequented by pirates, before the ship was taken under tow.[20]
In February 2018, Costa announced its partnership with the Italian football club, Juventus.[21]
In December 2019, Costa debuted Costa Smeralda and became the second cruise line to operate a cruise ship fully powered by liquefied natural gas (LNG), following AIDA's AIDAnova one year earlier.[22] Costa Smeralda was joined by her sister LNG ship, Costa Toscana, in 2021.
Owing to the Covid pandemic of 2020, Costa sold some of its ships, including the Costa Victoria and Costa neoRomantica to help cut costs. It also led to the continued long term layup of the Costa Magica and Costa Serena.[23]
In 2022, parent company Carnival Corp. announced they would be transferring ships out of the fleet to help balance overall fleet capacities due to the pandemic and the selling of numerous ships. It was announced the Costa Luminosa would be transferred to Carnival Cruise Line, the Costa Venezia and the Costa Firenze will join Carnival Fleet under the new "Carnival Fun Italian Style" concept in 2023 and 2024 respectively.[24]
In February 2023, it was announced that Costa Magica had been sold to Seajets, a Greek/Cypriot ferry company.[25][26]
On 31 March 2023, Costa Cruises celebrated its 75th anniversary.[27]
In May 2025, it was announced that Costa Fortuna had been sold to Margaritaville at Sea, leaving the fleet in September 2026.[28][29]
