Billionaire Gautam Adani-led Adani Group is mulling to enter the airport ground handling services business to diversify its aviation sector bid. Adani Group’s airport arm, Adani Airport Holdings (AAHL), is “evaluating” bids for ground handling services for two of the airports operated by it, including Mumbai and Ahmedabad, Bloomberg reported. The development comes at a time when Turkey’s Celebi Aviation’s operations at Indian airports have been halted after the Narendra Modi-led government revoked its security clearance license, citing national security-related issues.
