Refund-related complaints against airlines rise sharply in 2025, reaching a four-year high, government data cited in multiple reports shows. The increase is described as three times higher than in 2024, with complaints concentrated in the period following a December operational disruption by IndiGo. Authorities track complaints related to refunds, including delays and issues affecting reimbursement, and the latest figures indicate a sustained jump rather than a one-off spike. The reports link the timing of the surge to the December disruption, which led to disrupted operations and subsequent customer requests for refunds. While the data highlights the overall increase in refund complaints across the airline sector, the outlet reporting emphasizes IndiGo’s December disruption as a key trigger for the rise. The government figures do not indicate the resolution outcomes for individual cases, but they show a clear change in complaint volumes year-on-year and a peak following the disruption. The reports cite these trends as evidence of a broader customer-service pressure related to refund handling during the disrupted period.
