Round Trip or One Way?
The First Decision, and the Biggest
Sailing out of Skagway, down the Taiya Inlet: the Inside Passage doing its thing.
Every Alaska itinerary is built on one of two skeletons. Everything else (the ship, the ports, the airfare, whether Denali is even possible) hangs off this choice.
Round Trip
Seattle or Vancouver, back to where you started. Usually seven nights through the Inside Passage: Juneau, Skagway or Icy Strait, Ketchikan, and a glacier day. One flight city, one hotel city, the simplest air of any Alaska trip.
This is the right answer for most first-timers who just want to see Alaska without building a two-week production around it.
One Way (Cross-Gulf)
Between Vancouver and Whittier or Seward. You cross the Gulf of Alaska, which round trips never do. That’s where the extra glacier days like Hubbard Glacier and College Fjord come in. It’s also the only route that connects to a land tour without backtracking.
The trade: open-jaw flights (into one city, home from another) and a transfer day on the Alaska end. More planning. More Alaska.
Why Seattle Round Trips Stop in Victoria
It’s not a bonus port. It’s the law. The Passenger Vessel Services Act, a U.S. law dating to 1886, says a foreign-flagged ship sailing round trip from a U.S. port has to call at a foreign port along the way. Nearly every big cruise ship is foreign-flagged, so Seattle round trips check the box with a stop in Victoria, often just an evening. (People blame the Jones Act for this. That one’s cargo. This is the PVSA.)
The same law is why one-way cruises run to and from Vancouver instead of Seattle (a foreign-flagged ship can’t carry you one way between two U.S. ports) and why Vancouver round trips skip the compliance stop and often spend that time in Alaska instead.
The industry term for the Seattle round trip is a “closed-loop” cruise (start and end in the same U.S. port), and that one foreign stop is what keeps it legal. It comes with a quirk worth knowing: on a closed-loop sailing, U.S. citizens can technically cruise with a government photo ID and a certified birth certificate instead of a passport. We still say bring the passport. It’s the only document that flies you home from Canada if you ever have to leave the trip early. And some of the best Skagway excursions, the Yukon day trips, won’t board you without one.
The Alaska End: Whittier and Seward
One-way cruises start or end at one of two rail ports south of Anchorage, and which one depends on your line. Currently, Princess, Holland America, and Norwegian turn at Whittier, about 90 minutes from Anchorage by road, through a one-lane tunnel that cars and trains take turns using. Royal Caribbean and Celebrity use Seward, about two and a half hours out along the Seward Highway, where a brand-new terminal, the largest in Alaska, opened in 2026. Either way, budget a real transfer day on the Alaska end: ship, then road or rail, then Anchorage, then the airport. Port assignments shift season to season. We check them when we book you.
The Flight Piece: Let the Cruise Line Book the Air
Either route, you’re flying, and one-way routes mean open-jaw tickets that price strangely when you shop them yourself. Our standing recommendation: book the air through the cruise line’s own program. Every major line runs one: Princess EZair, Holland America Flight Ease, Flights by Royal for Royal Caribbean and Celebrity (renamed from Air2Sea in 2026), Carnival Fly2Fun. On the flexible fares, no air money is due until your cruise final payment and changes are free until then, which also means that when the fare drops, we can usually rebook you at the lower price. The fares themselves are routinely competitive with booking direct.
Then there’s travel day. Book through the line and its own air desk is watching your flights: if the airline melts down, lines like Princess, Holland America, and Royal Caribbean commit to rebooking you, up to and including flying you to the ship’s next port at no added airfare. Book the same flights yourself, and a cancelled connection is entirely your problem. The honest fine print: seats and schedule changes still belong to the airline, the cheapest restricted fares are non-refundable, and Norwegian’s program is a different animal: a fare play with less routing control and a required day-early arrival, not a protection play.
Why we push this: an open-jaw Alaska ticket is exactly where cruise-line air shines, and Alaska is the one trip where a missed connection can mean watching your ship leave without you. These programs change line by line and year by year; matching the right one to your trip is part of what we do, at no extra cost.
The honest advice: if this is your one Alaska trip and you can stomach the airfare logistics, go one way and add the land. If you want Alaska without the production, go round trip and don’t look back. Both are great trips. They’re just different trips.
