IndiGo's Market Share Plummets in December, Air India Group Surges

• IndiGo's domestic market share dropped sharply to 59.6% in December 2025 from 63.6% in November, a 400-basis-point decline.
• The decline was attributed to a scheduling crisis, software glitches, and issues with revised Flight Duty Time Limitations (FDTL) norms, leading to thousands of flight cancellations.
• The Air India Group capitalized on IndiGo's troubles, increasing its market share to 29.6% from 26.7%. Akasa Air and SpiceJet also saw modest gains.
• Overall domestic air traffic fell 4.1% year-on-year in December despite the peak travel season, reflecting the impact of widespread cancellations.
• Airlines received 29,212 passenger complaints in December 2025, with a complaint rate of 20.41 per 10,000 passengers, indicating significant service stress.

Why It Matters: IndiGo faced a significant market share drop in December due to operational issues, benefiting rivals like Air India Group.
