(Updated 6:09 p.m. EDT) -- Norwegian Cruise Line Holdings Ltd., the parent company of Norwegian Cruise Line, Oceania Cruises and Regent Seven Seas Cruises, has extended the suspension of cruise operations across all three brands through September 30, 2020, while select voyages have been canceled into October 2020 due to local regulations and restrictions. The October cancelations mainly affects the brands' previously-scheduled Pacific Coastal and Canada and New England itineraries.

In its press release, Norwegian notes that these cancelations do not affect September 2020 voyages from Seattle to Alaska.

"All voyages with embarkation dates from September 1 through September 30, 2020 [have been canceled], except for Seattle-based Alaska sailings on Norwegian Joy and Norwegian Bliss which are scheduled to operate," a Norwegian Cruise Line spokesperson noted in a statement provided to Cruise Critic. "We are hopeful that through the support of the Alaska delegation and openness of mayors of Alaska port towns, we have the potential to resume voyages in September."

Voyages to Alaska have been affected by Transport Canada's recent ban on cruises that runs through October 31, 2020. This includes Seattle-based sailings that are required to make a port stop in Victoria, British Columbia to satisfy requirements from the U.S. Passenger Vessel Services Act.

Affected cruises in October 2020 include Pacific Coastal itineraries aboard Norwegian Bliss and Norwegian Joy; and Canada & New England itineraries aboard Norwegian Breakaway, Norwegian Gem, Oceania's Insignia, and Regent's Seven Seas Navigator.

"The Company will continue to work in tandem with the U.S. Centers for Disease Control and Prevention (CDC), the federal government and global public health authorities to take all necessary precautions to ensure the health, safety and security of guests, crew and the communities visited," noted NCLH in a statement.

"Despite this further delay, we remain optimistic and expect to relaunch cruise operations in the near future. Given the fluid and evolving nature of the circumstances, we are making decisions as quickly and thoughtfully as possible and, as always, we are keeping our guests’ and travel partners’ best interests at heart. We are very sorry for any inconvenience these changes may cause."
