BILKULONLINE Delhi, July 8: Tata Group airlines have concluded the harmonisation of the operating procedures across its key functions, including harmonisation of the supporting manuals across all four carriers, reaching an important milestone in the merger of four airlines into two. Over the last 18 months, a team of more than 100 members have worked to align on the best practices and adopting common operating procedures. The result of this will be two separate manuals for the full-service carrier and the low-cost carrier. "This is an important milestone in the merger of the Tata Group airlines and we are grateful for the support received from the Ministry of Civil Aviation in terms of timely clearances for the merger process. We are also grateful to DGCA for their continuous guidance, systematic review and approval of the harmonized operating manuals. DGCA has guided our teams with a safety-first change management approach which is congruent with the safety-first priorities of the TATA Group.
