Because the State of Alaska has implemented dynamic or staircase pricing, fares can change not only every day - but sometimes between the morning & evening of the same day.
This system is understandably extremely unpopular as it makes planning difficult for both the ferry traveller and any agent trying to assist in planning a trip.
With this in mind please note that the Alaska fares on this site are basic fares so are estimates only: changes, based on the availability of a particular voyage, can and as a sailing gets closer, often happen.
For the most up-to-date fares on any particular Alaska ferry sailing, please call 1-800-686-0446 or email us at firstname.lastname@example.org. Quoted Alaska ferry prices on this site are subject to daily changes due to availability.
With the exception of the Alaska Marine ferries, fares for all other ferry systems on this site (BC Ferries; Seattle ferries; Inter Island ferries) enjoy fixed pricing as shown, and are not subject to dynamic pricing.
