Flight operations at Delhi’s Indira Gandhi International Airport (IGIA) returned to normal late Saturday night after an Air Traffic Control flight-planning software failure triggered delays and cancellations across more than 900 services beginning Friday afternoon. The Airports Authority of India said engineers installed a patched update and performed redundancy checks before clearing the backlog.
Business travellers bore the brunt, with carriers like Vistara and IndiGo reporting aircraft and crew out of position well into Sunday. Several Monday-morning departures have been retimed; corporate travel desks should proactively reissue e-tickets to avoid no-show penalties.

The incident has reignited debate over aviation IT resilience just weeks after a Parliamentary Standing Committee flagged outdated systems at metro airports. Industry groups are calling for a dedicated contingency-operations centre and real-time NOTAM alerts for travel managers.
International connectors—especially to Singapore, London and Dubai—are now operating on schedule, but baggage throughput remains slower than average as ground handlers clear piled-up containers. Passengers transiting Delhi early next week should allow longer minimum-connection times until airlines stabilise rosters.
