IndiGo experienced intermittent issues with its core reservation platform on August 19 and August 21, 2026, preventing some users from booking flights and displaying a 'no data available' message. The airline issued a public statement acknowledging the problems, attributing them to its Navitaire system, and directing customers to its contact center. IndiGo operates over 2,200 daily flights and held a 67.4 percent domestic market share in July.
