IndiGo flight from Mumbai-Phuket diverted to Chennai amid security threat

An IndiGo flight from Mumbai to Thailand's Phuket was diverted to Chennai in the wake of a security threat aboard the plane, a statement by the airlines said on Friday.

The flight will undergo necessary security checks before being allowed to take off, it added. However, what kind of security threat the flight experienced onboard, the commercial airline did not specify.

"IndiGo flight 6E 1089 operating from Mumbai to Phuket on 19 September 2025 was diverted to Chennai due to a security threat noticed onboard. As per the established protocol, relevant authorities were informed immediately and the flight will undergo necessary



security checks in Chennai," an official statement said.

Due to a night curfew in place at the Phuket airport, the resumption of the journey has been scheduled accordingly.

"We are making all efforts to minimise inconvenience to customers, including offering them refreshments and sharing regular updates with them. As always, the safety and security of our customers, crew and aircraft is our topmost priority," IndiGo said.

This came just days after an IndiGo flight carrying 151 passengers, including Samajwadi Party MP Dimple Yadav, was forced to abort takeoff after failing to lift off properly at Lucknow airport.
