American Airlines | Transportation | 136900 | $54.2B | United States | Mercer | Mercer HR Consulting | HRO (HR Outsourcing) | 2007 | n/a |
In 2007 American Airlines implemented Mercer HR Consulting under a $217 million, 7.5 year Business Transformation Outsourcing agreement with IBM to transform and manage many of the airline's human resource functions. The engagement was scoped to enhance HR services for American Airlines employees in the United States and Canada, covering more than 88,000 employees and centralizing transactional HR administration and service delivery.
Mercer HR Consulting, operating within the HRO (HR Outsourcing) category, was configured to deliver health and benefit administration, pension plan administration, compensation administration, and employee communication consulting services. IBM provided standardized HR process automation, human resources information technology support, and call center support, while Mercer provided administrative processing and consulting, enabling integrated case management and end to end benefits and compensation workflows.
The operational integration model paired IBM automated service platforms and call center infrastructure with Mercer’s administration modules to create a consolidated outsourced HR service layer for U.S. and Canadian operations. Deployment architecture centralized HR inquiries through IBM supported service centers, and established data and process handoffs so Mercer could manage benefit, pension and compensation data flows alongside advisory services.
Governance and workflow restructuring shifted transactional processing to the outsourcing partners, allowing American Airlines HR leadership to focus on strategic workforce imperatives. The contract created joint operational governance between American Airlines, IBM and Mercer, standardizing HR processes and instituting vendor managed workflows supported by ongoing process and technology investments.
The announcement explicitly cited expected outcomes including a more integrated and improved employee experience, reduced costs, improved operational efficiency, and access to innovative solutions, with the engagement contractually set at $217 million over 7.5 years. Mercer HR Consulting is named as the administrative and consulting provider within the HRO (HR Outsourcing) arrangement, delivering the core benefits, pension and compensation administration capabilities.

In 2016, Overseas Shipholding Group engaged Mercer HR Consulting within a HRO (HR Outsourcing) arrangement to support post‑separation employee matters under a transition services agreement with International Seaways in the United States. The SEC filing documents Mercer (Mercer (US) Inc.) as a third party benefits and HR technology vendor assigned to employee and benefits administration responsibilities in the TSA, establishing the implementation year and contractual scope.
Mercer HR Consulting is identified as supporting benefits administration and payroll support, with module usage inferred from the TSA listing of Mercer as a technology and third party vendor for benefits and HR services and from the contract timing noted in the SEC filing. Functional capabilities in scope align to benefits administration workflows and payroll processing support, enabling continuity of employee pay and benefits administration during the post‑separation transition.
Operational coverage is the US region under the TSA, with primary business functions impacted including human resources, payroll operations, and benefits administration for separated employee populations. Governance and delivery were structured through the transition services agreement, assigning Mercer defined responsibilities for HR and benefits elements as documented in the SEC filing, and positioning Mercer HR Consulting as the outsourced provider for those HR outsourcing services.
