Carnival Corp ended last year more than $10bn in the hole as a result of a global pandemic that has put the entire cruise industry into a complete deep freeze since March.
The world's largest cruiseship owner on Monday posted $10.2bn in losses for 2020, according to regulatory filings and news releases.
"2020 has proven to be a true testament to the resilience of our company," chief executive Arnold Donald said in a preliminary report on fourth-quarter earnings.
