Platinum Airport — Platinum, United States

Platinum Airport, coded PTU, serves the tiny Yup'ik community of Platinum on Alaska's remote southwestern coast along the Bering Sea. With no road connections to the rest of Alaska, PTU is the community's essential link for mail, cargo, medical evacuations, and passenger travel, typically served by small bush planes operated by regional Alaskan carriers. The village itself grew around a historic platinum mining operation in the early 20th century, giving both the settlement and the airport their name. Weather in this part of the Bering Sea coast is often harsh, making reliable air access through PTU critical for residents' access to healthcare, groceries, and connections to larger hub communities like Bethel.
