Leh Kushok Bakula Rimpochee Airport — Leh, India

IXL is the code for Kushok Bakula Rimpochee Airport in Leh, high in the Ladakh region of northern India. Sitting at roughly 3,250 meters above sea level, it is one of the highest commercial airports in the world and a dramatic entry point into the Himalayas, ringed by snow-capped peaks. The airport is also a dual-use military airfield due to Ladakh's strategic border position, and flights in and out require careful navigation given the thin air and mountainous approach. IXL sees a strong seasonal surge in tourist traffic during Ladakh's short summer travel window, when visitors flock to Leh for trekking, monastery visits, and high-altitude lake tours before winter closes many road routes.
