Qaisumah–Hafar Al-Batin International Airport — Qaisumah, Saudi Arabia

Shared between two communities in Saudi Arabia's northeast, Qaisumah–Hafar Al-Batin International Airport carries the code AQI and sits not far from the borders with Kuwait and Iraq. The field rises to 1,174 feet in elevation, and its single runway is split between civilian traffic and Royal Saudi Air Force use, a joint arrangement common at airports in this strategically sensitive border region. The area around Hafar Al-Batin drew international attention during the early 1990s Gulf War, when nearby military infrastructure supported coalition forces, and AQI's location reflects that long-standing defense role alongside its civilian passenger function today. Despite having only one runway, AQI carries large-airport status given the volume and strategic weight of traffic through this border-zone facility, with commercial flights linking Hafar Al-Batin to Riyadh, Dammam, and other Saudi cities for residents of this remote northeastern province. Few single-runway fields anywhere carry quite as much geopolitical weight as this one, given a frontier that saw real military significance within living memory.
