SpiceJet's share of India's domestic aviation market slipped to 0.6 per cent in September 2026, falling below regional carrier Star Air's 0.7 per cent for the first time, according to data released by the Directorate General of Civil Aviation (DGCA). The cash-strapped airline carried just 7.3 lakh passengers last month, a dramatic contraction from 59.2 lakh passengers in January, as financial pressures and grounded aircraft continued to erode its operational base.

A Year-Long Freefall in Market Share

SpiceJet's decline through 2026 has been steep and consistent. The airline commanded a 3.9 per cent market share in both January and February, before sliding to 1.2 per cent in August and reaching the historic low of 0.6 per cent in September. Passenger volumes have tracked the same downward curve, falling from 5.92 million in January to 7.3 lakh in September — a decline of over 87 per cent in nine months.

This is not a seasonal blip. Successive flight cancellations in recent months due to operational disruptions have affected scores of passengers, accelerating the erosion of consumer trust and bookings.

Star Air's Steady Climb in Context

By contrast, Star Air — a regional carrier with a far smaller overall footprint — held its market share at 0.6 per cent in January before inching up to 0.7 per cent by June and maintaining that level through September. The optics of a regional airline overtaking a once-major carrier on market share underscore how significantly SpiceJet's standing has deteriorated.

India's Domestic Aviation Market Under Pressure

The broader market also showed strain in September. India's domestic airlines collectively carried 11.823 million passengers last month, a decline of 6.49 per cent on an annual basis. High airfares, driven by elevated fuel costs and rupee depreciation, are weighing on demand. For the January–September period, domestic passenger traffic fell 0.82 per cent year-on-year to 122.35 million, compared with 123.37 million in the same period last year, the DGCA data showed.

Regulatory Action and Dark Pattern Penalty

SpiceJet's troubles extend beyond the tarmac. The Central Consumer Protection Authority (CCPA) imposed a penalty of ₹1 lakh on SpiceJet Limited in July for deploying deceptive design practices — commonly known as 'dark patterns' — on its flight booking platform. The airline was found to have automatically enrolled consumers into its loyalty programme and obtained consent for promotional communications through pre-selected options, violating consumer protection norms.

What Happens Next

With SpiceJet's market share now in single-digit fractions and its passenger base dramatically reduced, the airline faces an increasingly narrow window to stabilise operations and reassure travellers. Industry observers will watch whether fresh funding or a fleet recovery plan materialises before the peak winter travel season. Any further decline could put the airline's commercial viability into sharper question.
