Port Hedland International Airport — Port Hedland, Australia

Few airports anywhere exist as directly in service of a single export industry as Port Hedland International Airport, coded PHE, which sits beside one of the largest bulk shipping ports on the planet by tonnage, moving vast quantities of iron ore mined across Western Australia's Pilbara region toward steel mills in Asia. Mining companies including BHP and Fortescue Metals Group operate extensive fly-in fly-out arrangements through PHE, shuttling workers between the remote town and cities like Perth on rotating schedules that keep the airport busy with charter and scheduled flights alike despite Port Hedland's small permanent population. Summer temperatures here regularly climb into extreme heat, and the surrounding landscape consists of red desert plains punctuated by mining infrastructure and salt operations. Beyond its economic role, PHE also supports emergency and medical evacuation flights for the sparsely populated communities scattered across this remote stretch of coastline.
