Somewhere between the gray drizzle over Puget Sound and the first mountain walls outside the airplane window, a traveler working out how to reach Juneau realizes that no highway will get them there. The capital of Alaska sits behind water and ice, and every route in is by air or by sea. From Seattle the answer is a nonstop jet flight, with the Alaska Marine Highway ferry as the slower sea alternative.
How do you get from Seattle to Juneau?
You fly nonstop from Seattle-Tacoma International Airport to Juneau International Airport, and the flight takes about 2.5 hours. Seattle is Juneau’s only direct departure city in the Lower 48, so any other starting point means connecting through it or through Anchorage. The Alaska Marine Highway ferry is the other way in, but it does not leave from Seattle itself.
The nonstop flight
Alaska Airlines runs jet service between the two cities every day of the year, and Delta adds a seasonal schedule on the same pairing. Alaska Airlines is headquartered in SeaTac, Washington, in the Seattle metropolitan area, and Seattle-Tacoma is its primary hub. That means the Seattle end of the trip is the airline’s home ground, with its largest network of connections feeding the Juneau flight.
If you are coming from elsewhere in the country, you will usually connect in Seattle. Alaska Airlines belongs to the Oneworld alliance, and its frequent-flyer program is called Atmos Rewards, which matters if you are collecting miles on the way north. Window seats are worth thinking about. The approach to Juneau passes through channels and over mountains, and a clear day shows the Inside Passage laid out below you.
The ferry from Bellingham
The Alaska Marine Highway System has a mainline route that starts in Bellingham, Washington, and continues through Ketchikan, Wrangell, Petersburg and Juneau, with later stops at Haines, Skagway and Sitka. Seattle is not a port on that route, so a ferry traveler first has to reach Bellingham on their own.
Another mainline route runs between Ketchikan and Juneau by way of Wrangell, Petersburg and Sitka, then on to Haines and Skagway. Riders sometimes use one vessel and sometimes several to reach their final destination, with regional hubs in Ketchikan, Juneau, Whittier or Homer. Most communities in Southeast Alaska receive ferry service all year.
From the airport into town
Juneau International Airport is just 10 minutes from downtown Juneau. You step off the plane into a small, mountain-ringed airport and are in the city almost before your bags have stopped circling. The airport has a single runway and a separate seaplane landing area, which explains the steady hum of small floatplanes you hear throughout the day.
Beside the terminal, the Airport Dike Trail is open, a walking path where travelers with a layover or an early arrival can stretch their legs after the flight. Downtown, the old waterfront streets, the cruise docks and the state capital are all close to where you land.
Which options are there?
There are three ways to make the trip: Alaska Airlines year-round, Delta on a seasonal schedule, and the Alaska Marine Highway ferry from Bellingham. The two airlines fly the same Seattle-Tacoma to Juneau route, while the ferry follows the coast on a different timetable and from a different port.
| Option | Departs from | Arrives in | Service |
|---|---|---|---|
| Alaska Airlines | Seattle-Tacoma | Juneau | Daily jet service, year-round |
| Delta Air Lines | Seattle-Tacoma | Juneau | Seasonal |
| Alaska Marine Highway ferry | Bellingham | Juneau | Mainline route, year-round service for most Southeast communities |
Alaska Airlines
This is the carrier that ties Seattle to Juneau all twelve months. Its Juneau schedule also reaches Anchorage, Ketchikan, Petersburg, Sitka and Yakutat, so a traveler can continue to other Southeast towns without going back through Seattle. The airline began life as McGee Airways, which flew its first service between Anchorage and Bristol Bay, and the Alaska connection runs deep in the company.
For travelers heading to Glacier Bay, Alaska Airlines also flies a seasonal summer route that connects Juneau and Gustavus, the gateway town to the park. That makes Juneau a natural stepping stone for anyone who wants to add the national park to a Seattle trip.
Delta Air Lines
Delta serves Juneau from Seattle-Tacoma on a seasonal basis, which gives travelers a second airline to compare when their dates line up with its schedule. Because it is seasonal, it is a choice for the months when Delta is flying the route, and Alaska Airlines remains the service that is there when Delta is not.
It helps to look at both airlines side by side when you begin planning, since the two share the same pair of airports.
The Alaska Marine Highway
The ferry system covers 3,500 miles of coastline and serves over 30 communities, from Bellingham all the way out to Dutch Harbor in the Aleutian Chain. In Southeast Alaska, mainline vessels serve the larger towns and day boats provide regularly scheduled service to the smaller ones. Juneau is one of the system’s regional hubs.
From Juneau, scheduled routes fan out to Angoon, Haines, Kake, Pelican, Tenakee and Skagway, and a separate scheduled route links Gustavus with Hoonah. A traveler who arrives in Juneau by air can therefore still use the ferry for a side trip to one of these small communities. In the proposed winter 2026/27 schedule, the system will not travel to Prince Rupert, a detail for anyone who was thinking of using that Canadian port.
Seaplanes for the small towns
Alaska Seaplanes flies from Juneau International Airport to a long list of villages and towns that no road reaches: Angoon, Elfin Cove, Excursion Inlet, Gustavus, Haines, Hoonah, Kake, Klawock, Pelican, Petersburg, Sitka, Skagway and Tenakee Springs. It is not a way to reach Juneau from Seattle, but it is how travelers continue once they have landed.
The airport’s seaplane landing area explains why floatplanes are such a constant presence there. If your plans include a smaller Southeast community, Juneau is the place where the jet journey ends and the floatplane one begins.
What should you know before you travel from Seattle to Juneau?
The main thing to know is that Juneau is relatively remote and not completely accessible by car, so transportation is something to plan early. There is no road that links the capital with the rest of the state or with Seattle, and everything arrives by plane or boat.
Leaving Seattle
Seattle sits on an isthmus between Puget Sound and Lake Washington, and it is known as the cloudiest part of the continental United States, with 201 cloudy days in an average year. Gray mornings at the airport are normal, and the cloud often hides the mountains you will fly toward. It is one more reason the first view of Southeast Alaska can feel like a change of scene.
Pike Place Market, where the first Starbucks opened, is a classic stop for coffee, pastries and fish being thrown across the counter. The Space Needle, built for the 1962 World’s Fair, stands over the skyline and is often the first landmark visitors point out.
Arriving in Juneau
Juneau’s airport has one runway, which is 8,857 feet long and 150 feet wide, with a seaplane area beside it. The ground below is small and the mountains are close, so what you notice on arrival is how near everything is. Downtown Juneau begins almost at once, with its steep streets, old storefronts and the waterfront where ships tie up.
The airport is also an active place. Most of its traffic is air taxis, with scheduled commercial flights making up a smaller share. When a floatplane lifts off while a jet is waiting at the gate, you are seeing the Alaska version of an ordinary airport day.
Going on from Juneau
Juneau works as a hub for the rest of Southeast Alaska. Alaska Airlines flies to Sitka, Petersburg, Ketchikan and Yakutat, the ferry reaches Haines and Skagway, and floatplanes serve the smaller villages. If your plan is to see more than one town, you can build the whole trip around these links.
A summer flight to Gustavus connects with Glacier Bay, which is the route to take if the park is on your list. The ferry and the airlines overlap in many places, so you can mix them, flying one way and sailing the other, to see the coast from both sides.
Good to know before you go
The ferry and the seasonal Delta and Glacier Bay flights each run on their own calendars, so line up your dates with the one you intend to take.
