Petersburg James A Johnson Airport — Petersburg, United States

PSG, Petersburg James A. Johnson Airport, serves the small fishing community of Petersburg in Southeast Alaska, accessible only by air or water due to the region's rugged, roadless terrain. PSG is a critical lifeline for residents, supported by Essential Air Service flights connecting to larger Alaskan hubs like Juneau and Seattle via regional carriers. The airport also supports seaplane and floatplane traffic typical of the area, alongside fishing industry logistics and medical evacuation flights. Petersburg's Norwegian heritage and salmon fishing economy depend heavily on PSG for both passenger travel and freight, given the absence of any road connections to the outside world.
