Air India recorded a 20% revenue growth in March-April and is now focussing on increasing flying hours of each aircraft to add more trips. This comes as a boost to the airline which was put on the block by the government, as it was looking to divest its 76% share in the carrier. The airline is now focussing on improving operational efficiency in domestic and international sectors. Air India’s chairman Pradeep Singh Kharola said the airline benefitted from overall growth in the aviation market and the 20% revenue increase amounted to roughly Rs 3,000 crore. Kharola said that the new Tel Aviv route of the carrier is giving good returns and pinned high hopes of 70% revenue from the international routes.
