Nearly one-fifth — roughly 20% — of India's commercial airline fleet remains grounded as persistent supply-chain bottlenecks and global operational disruptions continue to keep airframes out of revenue service, credit rating agency ICRA has found.

The figure, cited in an assessment published by Trav Talk, places India's grounding rate at a level that materially affects domestic capacity even as passenger demand has returned to and in some periods exceeded pre-pandemic levels.

What does a one-fifth grounding rate imply?

ICRA's ratio means roughly one of every five aircraft in the Indian commercial fleet is parked rather than flying scheduled service. India operates one of the largest commercial aircraft fleets in Asia, with capacity spread across multiple scheduled carriers serving a domestic market that ranks third globally by passenger volume and continues to expand at a double-digit pace.

A grounding rate of this magnitude translates into hundreds of parked airframes when applied to the national fleet. The operational effect is a structural capacity shortage at a time when airlines have publicly committed to network expansion, and it puts pressure on both unit costs and the industry's growth trajectory.

Why are supply-chain issues still binding?

ICRA identifies two overlapping pressures behind the grounded fleet: continued parts and component shortages affecting major aircraft types, and disruption propagating from international events into Indian scheduling and operations. The two forces compound each other — even an airworthy aircraft cannot generate revenue if the operator cannot secure a slot, a crew rotation or a maintenance slot.

India's commercial fleet concentrates heavily on two narrowbody families — the Airbus A320 series and the Boeing 737 — both of which sit on multi-year global delivery backlogs. Component and engine lead times for these types have remained extended as manufacturers and engine makers work through accumulated order books, certification campaigns and ramp-up constraints. India is therefore exposed disproportionately when any single platform hits a reliability or supply problem.

What are the cost and capacity consequences?

Aircraft on the ground earn no revenue but continue to accrue financing, insurance, parking and depreciation costs. For Indian carriers, ICRA's framing suggests the financial hit is twofold: aircraft that cannot fly because required parts are unavailable, and operational disruption that prevents aircraft from being inducted into scheduled service even when technically available.

For passengers, the consequence is reduced frequency on high-demand domestic trunk routes and continued upward pressure on average fares during peak periods.

For lessors exposed to the Indian market, a higher-than-normal grounding rate tightens secondary-market availability for mid-life narrowbodies and affects residual-value assumptions on returned aircraft.

For the regulator, the data point is a reminder that fleet planning and airport infrastructure investment must keep pace with a fleet that cannot always fly at its certificated capacity.

What comes next?

ICRA's read ties the timing of fleet recovery to external supply conditions rather than to domestic demand. Indian operators will watch incremental improvements in component deliveries and stabilization of international operating conditions before revising fleet-utilization assumptions upward.

With new-aircraft delivery rates already slowing because of manufacturer and engine-maker constraints, the industry's near-term priority is operational rather than commercial: returning parked aircraft to scheduled service as quickly as the global supply chain permits, while preserving yields on a fleet running well below its certificated potential. Whether that ratio improves meaningfully in the coming year will depend less on Indian carriers and more on the pace at which global OEMs and engine suppliers restore a normal production cadence.
