Chaudhary Charan Singh International Airport — Lucknow, India

Serving Lucknow, the capital of Uttar Pradesh and India's most populous state, LKO carries the name of Chaudhary Charan Singh, a farmers' rights advocate who briefly served as India's prime minister in the late 1970s. The airport underwent substantial expansion in the 2010s, including a new integrated terminal designed with motifs referencing the region's Awadhi architectural heritage, reflecting Lucknow's long reputation as a center of Mughal and Nawabi-era culture, cuisine, and courtly manners. Rising traffic reflects Uttar Pradesh's enormous population base and growing middle class, as well as Lucknow's role as an administrative, educational, and commercial center for a state of more than 200 million people. LKO connects the city to major Indian metros including Delhi, Mumbai, and Bengaluru, alongside international routes to the Gulf region that serve a substantial community of Uttar Pradesh natives working abroad.
