An Indigo Airbus A320-200N, registration VT-ISV performing flight 6E-246 from Bangalore to Bhubaneswar (India), was cleared for takeoff from Bangalore's runway 09L and departed.

An Indigo Airbus A320-200N, registration VT-ITD performing flight 6E-455 from Bangalore to Kolkata (India), was cleared for takeoff from runway 09R and departed at the same time.

The separation between the two aircraft was lost after departure.

On May 30th 2022 India's DGCA reported that 6E-455 had been cleared for takeoff from the southern runway after south tower had properly coordinated with approach control. 6E-246 was cleared for takeoff by north tower, however without coordination with approach or south tower. The aircraft were on a converging heading, which approach control resolved by sending the aircraft onto diverging headings. The minimum separation was 100 feet vertical and 0.9nm horizontal (runways are just over 1.0nm apart). The north tower controller was dismissed, the occurrence was rated a serious incident and is being investigated by India's AIB.
