Lifuka Island Airport — Lifuka, Tonga

HPA refers to Lifuka Island Airport, a small airstrip in the Ha'apai island group of Tonga in the South Pacific. This airport is the primary air link for Lifuka and surrounding islands, which otherwise depend heavily on boat transport across Tonga's scattered archipelago. Real Tonga and other small regional carriers operate limited flights connecting HPA to the capital Nuku'alofa on Tongatapu. The Ha'apai group is known for pristine, less-touristed beaches and traditional Tongan village life, and the airport plays a critical role in supplying goods, medical access, and occasional tourism to this remote part of the kingdom.
