IndiGo’s scheduling and rostering flexibility is reduced immediately, limiting the airline’s ability to use extended duty-time leeway to absorb delays and recover disrupted rotations. Any renewed operational stress now has to be managed through cancellations, aircraft swaps, reserve crew, or timetable reductions rather than regulatory relief. The end of the monitored exemption period also raises the compliance bar for crew-duty breaches, increasing the risk of enforcement action if disruptions push operations outside statutory limits.
