"An unidentified person had called Vistara's call centre in Gurgaon in the morning today and claimed that the explosives have been planted on the Ahmedabad flight," Manoj Gangal, Director of the Ahmedabad's Sardar Vallabhbhai Patel International (SVPI) Airport, said.
The call centre then informed the local Vistara office here about the threat call, Gangal said.
"On receiving information, a Bomb Threat Assessment Committee (BTAC) was convened immediately at the SVPI Airport. The committee viewed the call as 'non specific' but advised for a complete security drill," said Gangal in a statement.
"After thorough checks, flight number UK 976 was cleared for operation at 2:15 pm today," said Gangal.
The Ahmedabad-Delhi flight, originally scheduled to depart at 10:55am, took off at 3:27pm today.
