Sultan Abdul Halim Airport — Alor Satar, Malaysia

Functioning as Alor Setar's principal air connection, Sultan Abdul Halim Airport carries the code AOR and rests barely 15 feet above the flat coastal plain of Kedah state in northern Peninsular Malaysia, not far from the Thai border. A lone runway handles the domestic flights linking Alor Setar with Kuala Lumpur and other Malaysian cities. The name honors a former Sultan of Kedah, tying the facility to the state's royal history. As a medium-sized regional airport, AOR mostly supports residents and businesses within Kedah rather than international travelers, many of whom continue onward by road or a short domestic hop after landing.
