Prayagraj Airport — Allahabad, India

IXD is the code for Prayagraj Airport, serving the city long known as Allahabad in Uttar Pradesh before its 2018 renaming to Prayagraj. The airport shares its runway with an Indian Air Force base, a common arrangement at many Indian civil enclaves. It gains particular importance during the Kumbh Mela and Magh Mela festivals, when pilgrim traffic to the sacred confluence of the Ganges and Yamuna rivers surges dramatically and additional flights are added. Outside festival periods it operates a modest schedule of domestic flights to cities like Delhi and Mumbai, primarily serving business travelers, students at the city's universities, and regional pilgrims visiting Prayagraj's religious sites year-round.
