The Carnival Vista cruise ship has received approval to start restricted passenger sailings out of the U.S., a Centers for Disease Control and Prevention spokeswoman told The Wall Street Journal. The Carnival Corp. ship, which had been approved to conduct test voyages from the Port of Galveston in Texas, is the third ship the CDC has greenlit for restricted passenger voyages, breaking more than a year of sailing hiatus in the U.S. CCL’s shares are slightly up on yesterday’s trading session but this new approval could be a game-changer for the stock.
