Fly-in access

Unalaska Airport (Tom Madsen Field) is the primary way in and out for people and time-sensitive freight.

Ferry access via the Alaska Marine Highway

The Alaska Marine Highway system serves Unalaska/Dutch Harbor, with routes extending as far west as Unalaska among its 32 total terminals across Alaska, British Columbia, and Washington.

A working port, not primarily a passenger port

Dutch Harbor's own port infrastructure is oriented substantially around the commercial fishing fleet rather than passenger traffic -- confirm current passenger ferry/flight schedules directly given real, seasonal Aleutian weather disruption risk.
