India’s largest airline IndiGo briefly soared to the top of the global aviation market on Wednesday, momentarily surpassing US-based Delta Air Lines to become the world’s most valuable airline by market capitalisation, according to Bloomberg data.

IndiGo’s stock surged during the day, reaching a peak of Rs 5,265. According to the data, around 02.30 pm, its market capitalisation hit $23.24 billion, edging past Delta’s $23.18 billion. However, the lead was short-lived and by market close, IndiGo’s valuation slipped slightly to $23.16 billion, just below Delta’s.

The airline holds over 60% share in the Indian aviation market and is considered one of the most efficient low-cost carriers globally. The recent surge in share price is attributed to improving financial performance, despite past struggles, including a net loss of Rs 987 crore in Q2FY25.

Looking ahead, IndiGo aims to significantly expand its international presence, with plans to increase overseas operations from an estimated 28% of its available seat kilometers (ASK) in FY25 to 40% by FY30. The airline also intends to add about 50 aircraft in FY26 to its current fleet of 439, of which 50 are currently grounded.
