However, after a thorough search of the Guwahati-bound flight AI-729, with 114 passengers on board, the call was found to be a hoax, airport officials said.
A woman has been arrested in this connection, police said.
At around 8.20 a.m. the Air India check-in counter received an anonymous call from a woman informing of a possible blast in the flight scheduled to take off at 9.45 a.m. Boarding to the plane was immediately suspended and the aircraft taken to an isolation bay for checking.
However, nothing threatening was found and the flight finally took off at 11.45 a.m. after a 115-minute delay.
This is the second hoax call to the city airport within 13 days, the previous one being received on September 7.
