He demanded an explanation from the airline saying how such things were happening.

Sources said Naidu was going to Hyderabad to attend a meeting on the 'Swachh Bharat' campaign. The flight was scheduled to depart at 1.45pm but due to the non-availability of the pilot it could take off only at 2.30 pm.

Soon after Naidu's tweets, Air India expressed regret for the inconvenience caused on Twitter.

Civil Aviation Minister Ashok Gajapathi Raju said he had asked Air India to conduct an inquiry and take action.
