Rising COVID-19 cases continue to hurt Carnival Corporation’s cruise lines, including Holland America Line and Princess Cruises, with both announcing additional cancellations due to pandemic-led uncertainties.   Carnival Corporation’s (CCL) Princess Cruises line announced that it is extending the pause on cruise sailings through May 14, 2021, as it continues to prepare its plans to meet the requirements of the U.S. Centers for Disease Control and Prevention (CDC). The development is also tied to the uncertainty associated with travel restrictions. The cruise line’s decision includes sailings in the Caribbean and the California Coast as well as early season Alaska and Europe cruises.
