Seabourn will launch cruises from Greece out of Athens beginning July 3, open to fully vaccinated guests.
The luxury line is the first of Carnival Corp.'s U.S.-based brands to announce a resumption of service outside of the U.S. for North American cruisers, following similar moves by Crystal Cruises, Royal Caribbean Group brands and Norwegian Cruise Line.

Seabourn expects significant demand for the cruises, said the line's vice president of global sales, Steve Smotrys, in a note to travel advisors.
"As you can imagine, the excitement and anticipation for these sailings is significant," he said.
The Seabourn Ovation will operate a seven-day itinerary to Nafplion on the Peloponnese; the Greek islands of Crete, Rhodes and Mykonos; and Limassol, Cyprus. On another itinerary, the ship will visit Paphos, Cyprus, and the Greek islands of Patmos, Rhodes, Santorini and Spetses. Each sailing also includes a sea day.
Josh Leibowitz, president of Seabourn, said, "We're grateful to the people of Greece for welcoming Seabourn back to the Mediterranean this summer."
Seabourn said it is finalizing additional details for these voyages, including information on its shoreside experiences, which it will share in the coming weeks.
