U.S. Airways merger: A strategic variance analysis of changes in post-merger performance

This case provides students the opportunity to apply strategic variance analysis (SVA) methodology in analyzing the performance changes realized in an airline merger. The U.S. Airways-America West merger provides an example of a complex, strategic action that simultaneously impacts firm size, unit pricing and costs, efficiency, and capacity for the combining airlines. This merger provides a rich example for the analysis since it combines U.S. Airways, a higher cost network airline that is geographically focused on the Eastern U.S., with America West, a low cost airline operating primarily along the Western U.S. The case includes merger and acquisition (M&A) theory discussing market power vs. efficiency motives for mergers and discusses the role of the U.S. Department of Justice and Federal Trade Commission in evaluating M&As and their impact on markets. The case asks students to serve as consultants applying the SVA methodology to the past U.S. Airways-America West merger and provide conclusions.
