An IndiGo flight en route from Pune to Hyderabad was diverted to Vijayawada on Sunday due to airspace congestion over Hyderabad, aviation officials confirm. Flight 6E‑6473 departed Pune at 08:43 am but, unable to land at Rajiv Gandhi International Airport immediately, made an unscheduled touchdown in Vijayawada before eventually reaching Hyderabad at 12:38 pm.
Sources within the aviation industry explain that intense traffic over Hyderabad airspace—likely compounded by peak-hour commercial flights and regional aircraft movements—left no immediate landing window for the Pune-originating flight. By diverting to Vijayawada, the airline ensured safe custody of passengers and aircraft, securing a deviation which prioritised safety and operational integrity. Officials emphasise that such diversions, while inconvenient, are routine in managing dynamic air traffic and unexpected congestion. An aviation authority representative noted that “airspace coordination across sectors is an evolving challenge as India’s aviation sector expands,” citing growing fleet sizes and increased flight frequency as underlying factors.
While the IndiGo flight’s diversion attracted attention locally, the incident also echoes a broader trend of growing pressure on Indian airspace—a result of a post-pandemic resurgence in air travel, surge in domestic connectivity, and evolving international schedules. Authorities are working on modernising airspace design, integrating radar coverage, and optimising flight paths across key corridors to support this rapid growth. Passenger impact was kept modest, with IndiGo providing assistance and timely updates. Ground staff in Vijayawada facilitated transfers, meals, and accommodation where necessary, reflecting the airline’s service protocols during unscheduled landings.
In a related occurrence on the same day, Air India faced its own diversion challenge. Flight AI357, operating from Tokyo’s Haneda to Delhi, registered elevated cabin temperatures mid-air, prompting a precautionary diversion to Kolkata. The aircraft landed safely and underwent inspection, with ground teams arranging alternative travel for passengers while conducting technical clearance. In a statement, an Air India spokesperson said: “Air India flight AI357, operating from Haneda to Delhi on 29 June 2025, made a precautionary diversion to Kolkata due to persistent warm temperatures experienced in the cabin. The aircraft landed safely in Kolkata and is currently undergoing checks… Our ground colleagues in Kolkata are providing all necessary support to passengers to minimise the inconvenience… Alternative arrangements are being made to fly our passengers to Delhi at the earliest. We regret the inconvenience caused to our passengers.”
Both diversions underscore the operational fallback protocols that airlines and regulators employ—prioritising passenger welfare and aircraft safety over schedule adherence. Analysts highlight that while airlines increasingly face capacity constraints in Indian airports, the root solution lies in modernising both airside and ground infrastructure. According to an aviation policymaker, “India’s aviation network is at a tipping point. We need advanced air traffic management systems, larger terminal capacities, and better coordination across airports to prevent such diversions.” Efforts are underway: the Airports Authority of India (AAI) is upgrading regional airports like Vijayawada with enhanced radar systems and additional runway capacity. Simultaneously, Hyderabad’s Rajiv Gandhi International Airport is expanding its infrastructure with a third runway and new satellite terminals, though the timeline extends to 2026–27.
Still, expanding physical infrastructure may not be enough. Industry experts advocate for integrated digital traffic flow management systems, which use real-time analytics to optimise take-off and landing slots across adjacent airports. They suggest that shared dispatch agreements and satellite-based navigation could reduce diversions caused by congestion. From the passenger perspective, such occurrences highlight the need for better communication. While airlines typically issue advisories and updates via mobile apps and announcements, real-time notifications during diversions can reduce confusion and anxiety.
A frequent flyer who experienced the Pune‑Hyderabad diversion remarked, “It was unsettling to realise we were landing in Vijayawada instead of Hyderabad. But once the airline explained the situation and started making new arrangements, the stress reduced.” Diversions, though operational, also involve ecological implications. Additional routing increases fuel burn and emissions—variables that airlines are increasingly under pressure to minimise in light of urban equity goals and carbon reduction targets. An air transport sustainability expert observed, “Each diversion increases carbon footprint. With more flights being rerouted, these emissions add up. Airlines must balance safety with greener route planning.”
IndiGo and Air India have both reaffirmed their commitment to environmental stewardship, citing ongoing fleet upgrades to more efficient aircraft and investments in sustainable fuels. The IndiGo flight involved in the diversion was operated on an Airbus A320neo-family aircraft noted for its fuel efficiency, helping offset some diversion-related emissions. The twin incidents of Sunday highlight a complex interplay of safety protocols, infrastructure limitations, service expectations, and environmental considerations. Rather than rare occurrences, such diversions may become routine unless systemic interventions are undertaken. India’s aviation stakeholders are urging coordinated planning at national and regional levels. Such coordination could involve decoupling peak-time slots, building satellite holding areas, and improving real-time slot management through digital platforms.
Passengers, too, will need to adapt—familiarising themselves with standard airline policies on diversions, compensation frameworks, and communication channels. As India strives towards equitable, sustainable, and resilient air travel systems, transparent management of such disruptions will be critical to public trust. In summary, the Pune‑Hyderabad flight diversion demonstrates both the strength and fragility of India’s aviation ecosystem. With bustling airspace and growing passenger volumes, these are early warning signals pointing to necessary modernization. Effective responses—spanning technology, infrastructure, and passenger engagement—are essential to sustain a safe, efficient, and climate-conscious future for air travel.
