Domestic air passenger volume grew 64.61 per cent to 10.35 million in September over the same period last year, according to data released by the aviation safety regulator Directorate General of Civil Aviation (DGCA) on Wednesday.

Indian domestic carriers (excluding newly launched Akasa Air) had flown a total of 7.66 million passengers on the local routes, the data showed.

Akasa Air commenced its flight services on domestic routes from August 7 this year.

The average passenger load factor of these carriers stood at 77.5 per cent against 72.5 per cent PLF delivered in August 2022, the DGCA data show.
