Summary
The UK government is set to evaluate two competing proposals for expanding Heathrow Airport, the country’s largest and busiest hub. Heathrow’s £49 billion plan includes a full-size 3,500-meter runway and relocation of the M25 highway, while the Arora Group’s under £25 billion proposal suggests a shorter 2,800-meter runway without relocating the M25. Both plans aim to commence operations by 2035. The expansion is expected to address capacity constraints and stimulate economic growth, though environmental concerns persist. The government has emphasized the use of sustainable aviation fuel (SAF) to align with net-zero emissions targets. Airlines, however, express concerns over potential fee increases. A decision is anticipated by the end of summer 2025.
