We deployed a large multi-disciplinary team to cover the full-scope of the merger transaction followed up by the post-merger integration. In a single team, airline experts, strategy consultants and financial modellers worked together to build the business model of the new company, implement the integration road map and model its business plan including financial impacts from road map actions. Our work also covered fleet management issues: asset life-cycle management, fleet turnover optimisation and fleet-use diversification.
