LONDON- A British Airways (BA) flight departing from Chennai, India (MAA) to London Heathrow (LHR) was compelled to make a U-turn mid-air on Sunday, June 22, 2025, due to the sudden closure of Iranian airspace. The diversion came in response to escalating geopolitical tensions in the region following reported US military activity.
Flight BA36, carrying 206 passengers, took off from Chennai at 6:24 AM IST, nearly 50 minutes behind schedule, and had exited Indian airspace when pilots received notice about the restricted airspace over Iran.

The aircraft, en route to London Heathrow (LHR), was flying over the Arabian Sea when the crew was informed of the Iranian airspace closure, reportedly linked to US strikes on nuclear facilities within Iran. In response, the crew immediately opted to reroute the aircraft back to its origin.
According to airport sources, the pilots contacted Chennai Air Traffic Control (ATC) and executed a safe return, landing at Chennai International Airport (MAA) at 8:50 AM IST.
The aircraft was guided to a parking bay by 9:20 AM, where all passengers were safely disembarked.
British Airways later confirmed the decision to return was a precautionary measure in light of the volatile situation in Iranian airspace.
Passengers were accommodated within the terminal and provided with refreshments while the aircraft was refueled.

Airport authorities announced that the same aircraft, Boeing 787-9 Dreamliner, was scheduled to resume its journey at approximately 10:30 AM IST, using a revised flight path that circumvents Iranian territory.
The unexpected closure of Iranian airspace did not just affect BA36. Several international departures from Chennai (MAA) experienced cascading delays due to necessary route adjustments and air traffic congestion.
A Kuwait Airways (KU) flight bound for Kuwait City (KWI), originally set to leave at 3:30 AM, eventually departed at 5:40 AM.
Likewise, services to Doha (DOH), Dubai (DXB), Sharjah (SHJ), and Abu Dhabi (AUH) reported delays of up to one hour. Flights operated by Qatar Airways (QR) and Emirates (EK) were among those affected.

Flight operations are under active surveillance by both airline authorities and airport ATC teams as the situation in the Middle East evolves.
With Iran’s airspace deemed unstable, carriers are expected to continue adopting alternative routes in the coming days to ensure passenger safety.
The geopolitical unrest has led to real-time recalibrations of international flight schedules, emphasizing the aviation sector’s need to respond swiftly to developing security concerns.

A British Airways (BA) flight en route to Chennai International Airport (MAA) made a precautionary return to London Heathrow Airport (LHR) on June 15, 2025, due to a technical issue detected mid-flight.
The Boeing 787-8 Dreamliner operating Flight BA35 circled over the Strait of Dover before safely landing back at its origin. British Airways confirmed the return was a standard safety measure and not an emergency landing.
British Airways Flight BA35, a scheduled service from London Heathrow (LHR) to Chennai (MAA), took off at 1:16 PM local time on June 15, 2025. Shortly after departure, the flight crew identified a technical irregularity and opted to return as a precautionary measure.
The aircraft, a Boeing 787-8 registered G-ZBJG and 11 years in service, was observed via Flightradar24 circling over the Strait of Dover before heading back to London. The maneuver allowed time for systems assessment and ensured a safe re-approach to the airport.
British Airways clarified that the return followed routine operational procedures. There was no emergency declared, and the flight landed safely without incident. Passengers disembarked normally, and no injuries were reported.
Post-Landing Support
Upon return to Heathrow (LHR), ground staff immediately assisted passengers with rebooking and accommodation arrangements. The airline’s technical team began inspecting the aircraft to determine the cause of the anomaly.
British Airways emphasized that its flight crews are trained to respond conservatively to onboard alerts. Returning to base allows maintenance to intervene early and helps avoid potential risks or delays later in the journey.
The airline also reaffirmed its dedication to passenger safety, noting that such operational decisions are guided by strict internal and international aviation protocols.
Events like the BA35 return highlight standard airline safety culture. Precautionary returns are a key aspect of aviation safety management systems. They enable crews to respond quickly to potential system alerts while minimizing passenger impact.
