Gustavus Airport — Gustavus, United States

GST identifies Gustavus Airport in Gustavus, Alaska, the primary air gateway to Glacier Bay National Park and Preserve. Because there are no roads connecting Gustavus to Juneau or other Alaskan communities, GST is essential infrastructure, handling scheduled flights from Juneau along with seasonal traffic tied to cruise ship visitors and park tourism. The airport features a long paved runway, a legacy of its construction during World War II as a military airfield. Summer months bring a noticeable spike in activity as visitors arrive to access glacier tours, kayaking, and wildlife viewing in the surrounding preserve, while winter traffic drops significantly with the smaller resident population.
