Choose the Sailing Date That Avoids the 35% Vehicle Surcharge

Washington State Ferries’ 35% peak-season surcharge for full-fare vehicles and drivers ends after Wednesday, Sept. 30, 2026. Travel on Thursday, Oct. 1, and the surcharge no longer applies. The sailing date—not the date you reserve or buy a ticket—determines which seasonal fare applies.

Enter the peak-season fare before any card fee to estimate the post-peak amount and savings.

Sailing date	Vehicle surcharge
Sept. 30, 2026	35%
Oct. 1, 2026	None

The surcharge applies annually from May 1 through Sept. 30 and does not apply to multi-ride cards, according to the WSDOT weekly update. These dates and percentages concern full-fare vehicle-and-driver travel. They should not be used to estimate a different fare category without checking it separately.

Oct. 1 Is the First Post-Peak Sailing Date

A full-fare vehicle trip on Sept. 30 remains inside the peak period. Moving that same trip to Oct. 1 puts it outside the annual surcharge window.

That one-day distinction matters even if the reservation was made weeks earlier. A reservation holds space for a particular vehicle on a specific sailing; it does not purchase the fare or lock in the price. The full fare is due at the time of travel under WSF’s vehicle reservation terms.

As a result, reserving an Oct. 1 sailing before Sept. 30 does not cause the peak surcharge to apply. The trip occurs after the surcharge ends, so it receives the post-peak fare. The reverse is also true: making a Sept. 30 reservation early does not remove the surcharge from that sailing.

This separates three dates that can otherwise be confused:

1. Reservation date: when you ask WSF to hold vehicle space.
2. Ticket purchase date: when you buy a fare product, if you buy it in advance.
3. Sailing date: the date that controls whether this seasonal surcharge applies.

For this fare change, the third date is the deciding one.

Reservable Routes Still Require a Sailing Reservation

Vehicle reservations are available and recommended on the Anacortes–San Juan Islands and Port Townsend–Coupeville routes, according to the WSF ticket store. If you move a trip from Sept. 30 to Oct. 1 on either route, reserve the Oct. 1 sailing rather than relying only on an advance ticket.

An advance ticket and a vehicle reservation do different jobs. WSF says buying a ticket early can save time at the tollbooth, but the ticket does not guarantee room on a sailing. The reservation is what holds vehicle space for the specified departure.

A practical sequence for those routes is:

1. Open the official fare calculator and compare the two travel dates for the same route and vehicle.
2. Confirm that Oct. 1 produces the post-peak fare for the trip you intend to take.
3. Reserve the specific Oct. 1 sailing.
4. Treat any advance ticket purchase as separate from the reservation.

The fare comparison should come before estimating whether the date change is worthwhile. Route, departure terminal and vehicle size can affect the actual amount, so the 35% surcharge alone does not reveal the dollar difference for a particular trip.

Seattle Vehicle Crossings Remain First-Come, First-Served

Seattle–Bainbridge and Seattle–Bremerton vehicle traffic is first-come, first-served. There is no car reservation to move from Sept. 30 to Oct. 1 on those crossings.

The seasonal fare boundary still applies. A full-fare vehicle and driver traveling Sept. 30 are on the peak side of the line, while the same fare category traveling Oct. 1 is on the post-peak side. The absence of reservations changes how drivers plan for space, not which date controls the surcharge.

Do not buy an advance ticket expecting it to function as a reservation on either Seattle route. It may reduce the transaction needed at the tollbooth, but it does not guarantee vehicle space on a particular sailing.

If changing the date is inconvenient, changing how you travel may be the more useful comparison. The destination-by-destination tradeoffs are covered in Washington State Ferries: Walk-On vs Car by Destination.

Removing 35% Cuts the Peak Total by About 26%

The end of a 35% markup does not make the peak total 35% cheaper. The percentage was added to the lower base fare, while the later reduction is measured against the larger peak total.

Using the draft’s simple example, a $100 fare with a 35% surcharge becomes $135 during peak season. When the surcharge ends, it returns to $100. The dollar reduction is $35, but $35 is about 26% of the $135 peak total.

Fare stage	Amount	Change
Post-peak base	$100	—
Peak total	$135	+35%
Return to base	$100	About −26%

To estimate the post-peak amount from a peak fare, divide the peak fare by 1.35. To estimate the dollar savings, subtract that result from the peak fare. The estimator above performs those two steps.

That calculation is only an estimate for the seasonal component. Actual fares vary by route and vehicle size. Use WSF’s date-specific fare calculator for the real Sept. 30 and Oct. 1 comparison rather than applying another route’s dollar savings to your trip.

The official calculator is also the safer choice when the two directions are sold differently or when the vehicle does not fit the standard category you first had in mind. The reliable comparison uses the same route, departure terminal, vehicle details and fare category on both dates. Only the travel date should change.

Multi-Ride Cards Do Not Receive This Surcharge

WSDOT’s announcement says the annual May 1–Sept. 30 surcharge does not apply to multi-ride cards. A traveler using one should not assume that moving a trip to Oct. 1 creates the same seasonal savings as it does for a full-fare vehicle-and-driver purchase.

This distinction also limits the scope of the 35% figure. It is not a blanket statement that every WSF product costs 35% more through Sept. 30. It describes the peak surcharge for the full-fare vehicle-and-driver category identified by WSDOT, with multi-ride cards expressly excluded.

If the trip involves another ticket type, compare that product directly in WSF’s fare tools. The available source does not provide a universal dollar amount for every route, vehicle or fare product.

The 3% Card Fee Continues After Sept. 30

The separate 3% card-payment recovery fee does not end on Oct. 1. WSF applies it to credit- and debit-card purchases made online, at kiosks and at terminals, according to WSF ticket information.

The seasonal surcharge and the card fee should therefore be treated as separate parts of the payment decision:

• The 35% peak surcharge for full-fare vehicles and drivers ends after Sept. 30.
• The 3% card-payment recovery fee remains in effect on Oct. 1.

Paying cash at a staffed terminal avoids the card fee. Paying from an ORCA card loaded away from a WSF facility also avoids it. Vehicle passes cannot be loaded onto ORCA, so that option does not replace the vehicle fare product needed for a car crossing.

Moving a trip to Oct. 1 can remove the seasonal surcharge while leaving the card fee unchanged. Do not interpret the end of peak season as the end of every fee associated with the transaction.

Ticket Direction Can Change the Relevant Total

Most vehicle-and-driver tickets are one way. Four named services use roundtrip vehicle tickets: Anacortes–San Juan Islands, Fauntleroy–Vashon, Southworth–Vashon and Point Defiance–Tahlequah.

That distinction makes it risky to estimate savings from a fare seen on another route. A quoted amount may represent one direction on one service but a roundtrip vehicle ticket on another. Even when both are subject to the same seasonal percentage, they are not interchangeable totals.

Use the departure terminal required by the official calculator. Then compare Sept. 30 and Oct. 1 without changing the route, direction, vehicle size or ticket category. This isolates the date change instead of mixing it with a different fare structure.

The Best Choice Depends on Which Part of the Trip Is Flexible

If the trip is fixed on Sept. 30, booking earlier does not avoid the peak surcharge. On a reservable route, a reservation can still hold space, but it cannot move the fare outside the seasonal window.

If the trip can move by one day, compare Sept. 30 and Oct. 1 in the official calculator. The Oct. 1 option is the post-peak choice for the full-fare vehicle-and-driver category described by WSDOT.

If the route is Anacortes–San Juan Islands or Port Townsend–Coupeville, make the Oct. 1 vehicle reservation after choosing the sailing. Buying only a ticket does not hold the space.

If the route is Seattle–Bainbridge or Seattle–Bremerton, there is no vehicle reservation to make. The fare changes on Oct. 1, but vehicle loading remains first-come, first-served.

If a multi-ride card applies, the cited peak surcharge does not apply to that card. Moving the trip solely to escape this surcharge would not produce the same fare change described for a full-fare vehicle trip.

If paying by credit or debit card, allow for the continuing 3% recovery fee. Oct. 1 removes the seasonal surcharge; it does not remove that payment fee.

The clean comparison is two otherwise identical trips: the same route, terminal, vehicle, fare category and payment assumptions, with one sailing on Sept. 30 and the other on Oct. 1. That shows the actual value of moving the trip across the peak-season boundary.
