IndiGo Confirms continued Operational Stability Ahead of Holiday Season; Back to Flying Over 1 Million Customers Every 3 Days

National, 24 December 2025: IndiGo, after having fully stabilized its operations since 09 December 2025, has been steadily adding capacity, within government guidelines. We have been consistently operating 2,100- 2,200 flights and carrying over 1 million customers every 3 days. We have been flying to and from all 138 operational destinations across our network while maintaining the IndiGo standards of ontime performance. With this, we are pleased to confirm that we are fully prepared to cater to the surge in demand during this holiday season.

In recent days, the aviation sector experienced industry-wide disruptions due to dense fog, particularly across northern India. Like all airlines, we were impacted too; however, the operations were effectively managed, under the circumstances, to maintain operational stability. With forecasts indicating a harsher winter ahead, we remain committed to ensuring reliability and minimizing disruptions across our network to ensure least inconvenience to our customers.

Looking ahead, we are all set to welcome our and India’s first Airbus A321XLR which will redefine medium-to-long haul flying for travellers in India and the subcontinent. We look forward to using these aircraft to connect Delhi and Mumbai with Athens starting 23 January 2026, as previously announced. We are also evaluating additional domestic and international destinations in line with our fleet expansion plans and will share further updates in due course.

We thank our customers for their faith in us. As always, we remain committed to giving wings to the nation and connecting India with key destinations around the world. – IndiGo spokesperson
