Narrative:
Two Boeing 787-8 Dreamliner aircraft were reportedly involved in an airprox event north of Delhi-Indira Gandhi International Airport in India.
Air India flight AI142 from Paris, a Boeing 787 registered VT-AND, and Air India flight AI154 from Vienna, a Boeing 787 registered VT-ANI, were involved in the occurrence.
One flight was at 22,000 feet and slightly ahead of the other, which was at 21,000 feet. Delhi ATC instructed the flight at 22,000 feet to descend, which meant crossing the level of the aircraft slightly behind it. The traffic collision avoidance system (TCAS) activated on both aircraft. A Traffic Advisory (TA) was almost immediately followed by a Resolution Advisory (RA).
The crew of the plane above immediately initiated a climb the one below responded by descending.

An AAI official reported to the Times of India that the incident occurred when the controller used the wrong call sign when issuing instructions to desend. The controller involved has been derostered from ATC duties and a preliminary inquiry has started.
