Phetchabun Airport — , Thailand

PHY is the code for Phetchabun Airport in Phetchabun Province, north-central Thailand, a mountainous agricultural region known for tamarind, coffee, and scenic national parks. The airport provides limited domestic connections to Bangkok, supporting travelers visiting Phetchabun's cooler highland attractions like Phu Thap Boek and Khao Kho, which have become popular weekend destinations for Thai tourists seeking relief from lowland heat. Service at PHY has historically been intermittent, with route availability depending on seasonal demand and airline decisions. The airport remains a small, regional facility with a single runway, primarily serving domestic tourism traffic rather than international travelers.
