This document provides a strategic analysis of Virgin Group and Virgin Atlantic airline. It analyzes Virgin Group's corporate strategy as a portfolio of autonomous business units. It then examines Virgin Atlantic's business strategy using Barney's VRIN framework, finding that Virgin Atlantic has a sustainable competitive advantage through its valuable customer service and rare cabin crew, as well as its imperfectly imitable and non-substitutable Virgin brand. An external analysis using Porter's five forces model shows the airline industry faces high intensity rivalry and powerful buyers, though barriers to entry are also high. The document evaluates Virgin Atlantic's strengths in customer experience and the Virgin brand, but also weaknesses in facing strong competition.
