IndiGo            - Airbus A320 - VT-IEW - 6E 398 - Delhi > Bagdogra
AirAsia India - Airbus A320 - VT-JRT - I5 768 - Bagdogra > Delhi

As both flights came near waypoint BODOG which is on airway Q18, AirAsia India flight which was cruising at altitude of FL360 (36,000ft) descends down to FL320 (32,000ft) at 08:05:29 UTC at speed of 458 KTS crossing the path of Bagdogra bound IndiGo flight which was cruising at FL330 (33,000ft) at speed of 463 KTS. 

While the air traffic control (ATC) Varanasi - had cleared the AirAsia India to descend to FL340 (34,000ft) and maintain it, however AirAsia flight continue to descend to FL320 which caused near miss with TCAS (Traffic Collision Avoidance System) alerts.
