Sultan Azlan Shah Airport — Ipoh, Malaysia

IPH honors Sultan Azlan Shah, a former Malaysian king who also served as the hereditary ruler of Perak state and earlier built a reputation as a respected jurist before ascending the throne. The airport serves Ipoh, a city built on tin-mining wealth in the nineteenth and twentieth centuries and now better known for limestone hills riddled with cave temples and a food culture that includes a distinctive style of milky white coffee served throughout Malaysia. Scheduled flights connect IPH mainly to Kuala Lumpur and other Malaysian points, with budget carriers periodically adding seasonal routes to neighboring countries such as Singapore and Thailand as demand allows. Surrounded by karst limestone formations that draw rock climbers and cave explorers, the region around the airport has increasingly promoted adventure tourism alongside its more traditional appeal as a heritage and culinary destination for domestic Malaysian travelers.
