This report provides a comprehensive analysis of the London Heathrow Airport (LHR) expansion plans. It begins with a timeline analysis of the expansion plans since 1993, detailing key decisions and events, along with media analysis. The report then utilizes an airport analysis audit tool to assess situational and terminal factors, including passenger numbers, air traffic movements, and terminal layouts. Furthermore, it identifies and justifies the most significant planning challenges impacting LHR, such as legal challenges, environmental concerns, and stakeholder approval. A detailed stakeholder analysis of four primary stakeholder groups—local and national government, environmentalists, the local community, and capital investment groups—is presented. Finally, the report presents balanced arguments for and against the expansion plans and concludes with a justified decision regarding the expansion plans.
