IndiGo briefly became the world's largest airline in terms of market capitalisation on Wednesday, but slipped again to the second spot as the stock of US-based Delta Air Lines Inc. soared after the Wall Street opened.
Earlier on Wednesday, IndiGo's parent entity InterGlobe Aviation Ltd., with a $23.15 billion market cap, had become the largest among its international peers.
The first position was reclaimed by Delta Air Lines, whose market cap surged to $24.42 billion after the US markets opened, as per Bloomberg data.
Delta Airlines' stock surged over 9% in trade on Wednesday, and the company was also the top gainer in the S&P 500 index. This led to the company regaining its leading position among the other airlines.
