To finance the venture, Arison turned to his friend Meshulam Riklis, who owned Boston-based American International Travel Service (AITS).

Carnival would adapt and evolve the green Canadian Pacific livery for their new logo, changing the colors to red, white and blue as seen today.

[11] In 1984, Carnival would introduce a new television marketing campaign during this time, starring Kathie Lee Gifford, who continues to be a longtime collaborator with the line.

[12] Following the success of the Tropicale, and increased competition in Miami with newer ships, Carnival ordered the Holiday in 1985, followed by the Jubilee in 1986 and Celebration in 1987.

[11] In 1993, Carnival began to get rid of their older second-hand tonnage, and sold their first ship, Mardi Gras, after 21 years of service with the line.

[23] In January 2017, Michael Thamm was appointed CEO of Carnival Asia to oversee operations in China and the surrounding region.

On July 31, 2021, after numerous delays, the highly anticipated Mardi Gras entered service, sailing year round from Port Canaveral.

It was also announced that they would receive the blue livery with twist, having a yellow stripe instead of the red and white ones found on the other Carnival ships.

An industry news item estimated that this would enable Carnival to continue operating for roughly a year in a situation where none of the ships was sailing.

[45] All cruises were cancelled in March 2020 due to the worldwide pandemic and eventually, 55 passengers on ships owned by Carnival Corporation & plc were reported as having died.

The adjusted net loss in the third quarter for Carnival Corporation & plc was reported to the U.S. Securities and Exchange Commission as US$1.7 billion.

[53] On September 16, 2020, Carnival Cruise Line extended the suspension of four of its ships sailings well beyond October to complete required dry-dock enhancements.

By September 27, 2020, however, "Costa Cruises will be available for all European citizens who are residents in any of the countries listed in the most recent decree from the Prime Minister of Italy" according to a news report.

[55] The corporate parent's 4th quarter (ending November 30, 2020) financial statement released on January 11, 2021, indicated that one extra ship, in addition to the 18 previously planned, was to be sold.

The contract was widely criticized, because the vessels were never fully utilized, and Carnival received more money than it would have earned by using the ships in their normal rotation.

[59] For example, a junior waiter would earn a basic salary of £250 a month for shifts lasting at least 11 hours, seven days a week.

[59] In response to this controversy, the general secretary of the Trades Union Congress, Brendan Barber, commented: "It's high time the disgraceful practice of allowing the shipping industry to pay poverty wages to workers who don't live in the UK was stopped.

[61] Since 2017, Carnival Corporation has been on probation, after having been found to "illegally dumping oil into the ocean from its Princess Cruises ships and lying about the scheme."

[62] The court summary states that "Princess was convicted and sentenced in April 2017, after pleading guilty to felony charges stemming from its deliberate dumping of oil-contaminated waste from one of its vessels and intentional acts to cover it up".

[65] The next day, a Senior US District Judge approved the deal, and confirmed that probation would continue for three years, after CEO Arnold Donald said, "The company pleads guilty.

[66] In June 2019, Carnival Corporation and its Princess subsidiary agreed to pay a criminal penalty of $20 million for further environmental violations that include dumping plastic waste into the ocean.

[69] On February 10, 2013, Carnival Triumph, with 3,143 passengers aboard, suffered an engine room fire, leaving the ship adrift for four days in the Gulf of Mexico.

[72][73] In subsequent litigation, Carnival documents were uncovered that revealed multiple generator maintenance problems creating a "disaster waiting to happen".

[74] On March 14, 2013, Carnival Dream experienced an emergency generator failure while docked in port at Philipsburg, Sint Maarten.

[84] In the evening on September 20, 2019, while passing through Panama Canal, the former Carnival Fantasy collided with the lock's wall and sustained damage to the aft superstructure.

[85] On October 9, 2019, a 23-year-old passenger fell off a railing where he was sitting onto a lower deck while the Carnival Valor was sailing near Louisiana.

[94] On June 28, 2022, a large fight aboard the Carnival Magic around 5:30 am prompted NYPD response upon arrival into New York City.

[95] In June 2022, the New York Department of Financial Services announced a US$5 million fine for Carnival due to cybersecurity violations.

The department stated that the violations were "significant" and that from 2019 to 2021 Carnival had four security breaches that exposed considerable amounts of consumer data.

The department went on to state that Carnival failed to meet security regulation by not using two factor authentication and additionally did not report one of their data breaches.
