Passengers aboard Carnival Luminosa are facing an unexpectedly long stretch at sea after the ship cancelled its final two scheduled Alaska stops on its way to Japan.
Passengers currently onboard have reported that Icy Strait Point on September 24 and scenic cruising at Hubbard Glacier on September 25 have been cancelled, with pre-booked excursions for Icy Strait Point already being refunded.
The changes mean that after departing Ketchikan on September 23, Carnival Luminosa will effectively begin its Pacific crossing towards Japan two days earlier than originally planned.
Instead of the already substantial seven consecutive sea days before arriving in Otaru, passengers are now facing eight days without a port call.
And there appears to be a very good reason for it.
Weather changes Luminosa's route across the Pacific
Passengers onboard Carnival Luminosa have been advised that weather conditions mean the ship will need to follow a more southerly route across the Pacific in order to remain on schedule for Japan.
While Carnival had not published a public notice confirming the itinerary changes at the time of writing, the weather situation in the Gulf of Alaska supports the concerns being reported from onboard.
The US National Weather Service is forecasting deteriorating conditions across parts of the Gulf of Alaska over the coming days.
One offshore forecast shows winds increasing to 20–35 knots Thursday night, with seas forecast to build to 13–19 feet — around 4 to 5.8 metres — by Saturday.
Other parts of the Gulf have been subject to gale warnings, with winds reaching 35 knots and seas around 12 feet. The National Weather Service says a developing low is moving into the southern and eastern Gulf before curling into the central Gulf.
That makes heading further north towards Icy Strait Point and Hubbard Glacier before beginning the Pacific crossing a considerably different proposition from turning towards a more southerly route after Ketchikan.
Two of the cruise's Alaska highlights are gone
The change will undoubtedly be disappointing for passengers, particularly as both cancelled destinations were major features of the Alaska portion of the transpacific itinerary.
Carnival Luminosa departed San Francisco on September 20 for its repositioning cruise to Japan.
The original itinerary called for:
September 23: Ketchikan
September 24: Icy Strait Point
September 25: Hubbard Glacier
September 26 – October 2: Pacific crossing
October 3: Otaru, Japan
Published itineraries still showed both Icy Strait Point and Hubbard Glacier as scheduled at the time of writing. Icy Strait Point's published cruise schedule was also still listing Carnival Luminosa for September 24.
Carnival itself originally promoted the 18-night repositioning voyage as including Alaska calls before Luminosa crossed the Pacific for Japan.
With Icy Strait Point and Hubbard Glacier now removed, however, Ketchikan becomes Luminosa's final stop in North America.
Its next scheduled port isn't until Otaru on October 3.
Eight days at sea before Japan
Seven consecutive days at sea was already one of the defining features of this particular transpacific cruise.
Now passengers get two more.
Once Luminosa leaves Ketchikan, passengers will spend approximately eight days aboard the ship without another port call before arriving in Otaru.
There is an additional quirk in the calendar during the crossing: the ship crosses the International Date Line, meaning passengers effectively skip a calendar date as they travel west towards Japan. Published versions of the original itinerary show September 30 as the International Date Line crossing.
For people who love sea days, eight in a row might sound fantastic.
For passengers who booked the cruise partly for the Alaska experience — particularly Hubbard Glacier — it could be a much harder pill to swallow.
Hubbard Glacier would have taken Luminosa further north
The geography helps explain why dropping the two destinations can give the ship significantly more flexibility.
Icy Strait Point sits west of Juneau, while Hubbard Glacier is considerably farther north in Yakutat Bay on the northern Gulf of Alaska.
The original itinerary therefore required Luminosa to continue north after Ketchikan before turning away from Alaska and beginning the long journey towards Japan.
Removing both destinations allows the ship to start making its way south and west earlier, potentially providing more options for navigating around difficult North Pacific conditions.
Exactly what route Luminosa ultimately takes will depend on conditions and operational decisions made onboard.
Luminosa is repositioning back towards Australia
The transpacific voyage comes at the end of Carnival Luminosa's first season sailing from San Francisco.
The ship spent the northern summer operating Alaska and Mexico cruises from the Californian port after arriving from Australia earlier this year.
This current repositioning voyage combines Alaska with four Japanese destinations — Otaru, Aomori, Shimizu and Kobe — before finishing in Tokyo on October 9.
Luminosa will then undergo dry dock work in Asia before returning for another Australian summer season.
For now, however, passengers onboard have quite a stretch ahead of them.
Eight days at sea.
As someone who genuinely loves a long run of sea days, even I'd have to admit that's getting pretty serious. 😂
Voyage Ready will update this story if Carnival Cruise Line releases further information about the itinerary change.
