New Delhi, Aug. 19 -- As many as 5,706 flights were cancelled by Indian carriers due to regulatory issues and geopolitical issues this year till June 30, the civil aviation ministry informed Rajya Sabha on Monday. In a written response to Congress MPs Phulo Devi Netam and Ranjeet Ranjan, Minister of State (MoS) for civil aviation Murlidhar Mohol revealed the airline-wise flight cancellations and or reschedulings in 2025, noting that IndiGo recorded the maximum cancellations. According to the data provided by the ministry, domestic airlines carried 7.34% more passengers between January and June 2025 compared to the same period last year. The total number of departures till June 30 stood at 356,811 for IndiGo, 161,204 for the Air India Group (including Air India Express), 24,447 for Akasa Air, 10,141 for Alliance Air, and 19,476 for SpiceJet.

The Air India Group cancelled 1,468 flights in this period, while Akasa reported 64, Alliance Air 499, and SpiceJet 401. These disruptions not only inconvenienced passengers, but also imposed financial strain on carriers, the MoS said. "Airlines incur costs due to delays and cancellations, including additional fuel, crew overtime, maintenance, airport fees, and rebooking expenses. Further, Airlines are required to provide refunds or compensation to passengers for cancellations or significant delays," Mohol said in the reply. The DGCA mandates that airlines provide refunds or compensation under rules titled "Facilities to be provided to passengers by airlines due to denied boarding, cancellation of flights and delays in flights"....
