Repositioning Cruises from Seattle: Panama Canal, Japan and Australia

Repositioning cruises from Seattle are long voyages. When the Alaska season ends in late September, ships based in Seattle leave for Florida, the Gulf Coast or New York through the Panama Canal, for Japan across the North Pacific, or for Australia by way of Hawaii and the South Pacific. In March and April the same routes run in reverse as ships arrive for the next Alaska season. The shortest is 13 nights and the longest runs past a month.

What Seattle does not have is the short four to seven night coastal run to California that many guides describe. Those voyages exist, but they start or end in Vancouver, for a legal reason explained below. If a short coastal trip is what you want, read our guide to repositioning cruises from Vancouver instead.

What sails from Seattle: our data

Of the 517 repositioning sailings in our repositioning cruise finder, each checked on the cruise line’s own website in late September 2026, 14 start or end in Seattle between October 2026 and December 2027. Carnival has four, Holland America and Royal Caribbean three each, and MSC and Norwegian two each.

The timing is tight. Eight of the 14 sailings leave Seattle between September 12 and October 1, 2027, and five of the six spring arrivals land between March 28 and April 11, 2027. The finder updates as lines add dates, so the link above is the current list.

Why there are no coastal runs from Seattle to California

The Passenger Vessel Services Act controls what a foreign-flagged ship can do between US ports, and almost every cruise ship is foreign-flagged. Under the rules CBP publishes, a passenger who boards in one US port and leaves in a different one must have traveled to a “distant foreign port” on the way. Ports in Canada, Mexico, Central America, Bermuda and most of the Caribbean count as nearby, so a stop in Victoria or Ensenada does not help. The penalty falls on the cruise line, per passenger, which is why lines simply do not sell those trips.

That shapes the whole Seattle schedule:

• Round trips to Alaska are fine. A cruise that leaves and returns to Seattle only needs a nearby foreign port, which is why Seattle’s Alaska cruises call at Victoria or another British Columbia port.
• Seattle to California one way is not. Coastal repositioning between the Pacific Northwest and Los Angeles or San Diego therefore runs from Vancouver. Some of those ships call at Seattle mid-voyage, but you cannot board or leave there.
• Seattle to Florida through the canal is fine. Every Seattle canal itinerary in our data calls at Cartagena, Colombia, a distant foreign port. Elsewhere, lines use Aruba or Curacao, which CBP also treats as distant.
• Seattle to Japan or Australia is fine. The voyage ends abroad.

The fall departures

Through the Panama Canal. Carnival Spirit leaves Seattle for Galveston in September 2027 (16 nights), after doing Seattle to Mobile in October 2026. MSC Poesia sails Seattle to Miami in late September 2027 (19 nights). These are the most practical Seattle repositioning cruises for American passengers: domestic flights at both ends, and a full canal transit on the way. For the transit itself, see our Panama Canal repositioning guide.

To Japan. Holland America’s Noordam (13 nights, September 12), Royal Caribbean’s Quantum of the Seas (14 nights, September 27) and Norwegian Jade (15 nights, September 28) all sail from Seattle to Tokyo or Yokohama in 2027. The route bends north along Alaska and the Aleutians, so several of them start with Ketchikan, Sitka or Whittier. This is the closest thing to a one-way Alaska cruise out of Seattle. Our guide to repositioning cruises to Japan and Asia covers the route, the weather and the date line.

To Australia. Holland America’s Westerdam leaves for Sydney on September 19, 2027 (34 nights), and Royal Caribbean’s Voyager of the Seas leaves for Brisbane on October 1 (25 nights) by way of Honolulu, Tahiti and Vanuatu. These are among the longest voyages anyone sells from a US port as a single booking.

Pairing with a final Alaska cruise. Because the repositioning voyage leaves Seattle a few days after the ship’s last Alaska round trip returns, the two can often be booked back to back. Both legs are legal under the cabotage rules: the Alaska cruise returns to the port it left from, and the repositioning voyage ends abroad or reaches Cartagena. Ask the line whether you can keep the same cabin and stay aboard on turnaround day. It is the simplest way to turn a week in Alaska into three weeks at sea, and it spares you a second flight to Seattle.

What the weather does. The first days south toward California or west toward the Aleutians are often cool and gray, and the open-ocean stretches can carry a long swell. On the canal routes the air warms once the ship passes Southern California; on the Japan routes it stays cool for most of the crossing. Pack layers either way.

The spring arrivals: repositioning cruises to Alaska’s home port

When people search for a repositioning cruise to Alaska, what Seattle actually offers is the spring arrival of a ship that will spend the summer sailing from Seattle to Alaska. In 2027 those arrivals come from three directions:

• From the Gulf and Florida: Carnival Spirit from Mobile (March 29, 16 nights), Carnival Legend from Tampa (April 4, 16 nights) and MSC Poesia from Miami (April 8, 18 nights), all through the canal.
• From New York: Norwegian Bliss, 22 nights via Cartagena, the canal, Puerto Vallarta and San Francisco (April 9).
• From Australia: Holland America’s Noordam from Sydney (March 28, 29 nights via Fiji, American Samoa and Kona) and Royal Caribbean’s Quantum of the Seas from Brisbane (April 11, 23 nights via Tahiti and Honolulu).

None of these stop in Alaska, because the ship’s first Alaska cruise starts from Seattle a few days after it arrives. If you want Alaska ports on a one-way spring voyage, the eastbound crossings from Japan to Vancouver are the ones that include them, often with Kodiak, Juneau and Ketchikan.

Seattle’s cruise piers

Seattle has two cruise terminals, about ten minutes apart by road.

Details are from the Port of Seattle’s Pier 91 page and its Pier 66 page. Parking makes sense only if you are sailing into Seattle and driving home. On a fall departure you will not be coming back, so arrange a drop-off.

Flights, documents and the trip home

Getting there. Seattle is a domestic airport for US travelers, with nonstop flights from most large cities. For a 3 p.m. or 4 p.m. sailing, arriving the day before is the safer plan: a missed connection on a repositioning cruise means a missed voyage, with no easy port to catch up at.

Documents. Every sailing here leaves the US and ends somewhere other than where it began, so the closed-loop exception that lets US citizens cruise on a birth certificate does not apply. Bring a passport book. For Japan, Australia or New Zealand, check the entry rules for each country, including Australia’s Electronic Travel Authority and New Zealand’s NZeTA, which every cruise passenger needs regardless of nationality.

The flight home. After a canal crossing it is a domestic one-way from Miami, Galveston or Mobile. After a Japan or Australia crossing it is a long-haul one-way, which is where the real cost of these trips sits. Book it with the cruise, and see our guide to flights home after a repositioning cruise for how late you can safely fly on arrival day.

When to choose Vancouver instead

Seattle and Vancouver share the Alaska fleet, but their repositioning schedules are different products. Choose Vancouver if you want:

• A short coastal voyage to Los Angeles or San Diego (4 to 7 nights), which Seattle cannot offer.
• A one-way cruise to Hawaii. Our Hawaii repositioning guide explains why these start in Canada.
• More choice of Japan crossings, including Viking, Oceania, Regent and Princess.

Choose Seattle if you want a long voyage with a US start, especially a canal transit to Florida or the Gulf, and you would rather not deal with a border crossing on the way to the ship. On numbers alone, Vancouver had 52 sailings in our finder to Seattle’s 14, so check both before you decide.
