Carnival Corp. has canceled cruises departing from Miami and Port Canaveral, Fla., this November.

The cruise operator earlier this month canceled all domestic cruises through the end of this year except for those departing from the two Florida ports. It previously planned to restart operations out of those ports when the Centers for Disease Control and Prevention lifts its No Sail Order Oct. 31, but the company “has now determined that November 2020 operations will not be feasible,” it said in a statement.

The cancellations affect cruises on six Carnival Cruise Line ships.

“Cruises currently scheduled for December from those two homeports remain in place for the time being while Carnival evaluates options,” the company added.

Carnival also canceled five cruises scheduled to depart from Sydney, Australia between Jan. 16 and Feb. 8.

Carnival, headquartered in Miami, is the parent company of Cunard and Princess Cruises, both based in Santa Clarita. Those cruise lines are scheduled to restart operations in March and April, respectively.

The cancellations drove shares of Carnival (CCL) down 48 cents, or 3 percent, to $15.21 on the New York Stock Exchange on Monday, a day when the major stock indexes increased from 0.88 percent to 2.56 percent.
