Heathrow unveils £1.3 billion terminal upgrade and AI-powered turnaround system

Heathrow unveils £1.3 billion terminal upgrade and AI-powered turnaround system
Heathrow Airport has announced a £1.3 billion capital programme starting in 2026 that will modernise Terminals 2 and 4 and introduce AI-driven apron management designed to cut aircraft turnaround times. The five-year plan—part of a wider £49 billion vision—includes a high-capacity baggage system in Terminal 2 capable of processing 31,000 bags per day and a new multi-storey car park for Terminal 4.

A network of machine-vision cameras will feed real-time data to operations control, enabling Heathrow to meet its target of 80 percent on-time departures by 2029. Accessibility features such as dedicated security lanes and a ‘Tailored Travel Guide’ app will support passengers with reduced mobility—an important consideration as regulators push airports to improve inclusivity.

For corporate travel buyers, the upgrade promises shorter connection times and reduced mis-baggage risk once live. However, construction work (phased through 2031) may temporarily restrict some airside routes and parking capacity; travel managers should monitor Heathrow NOTAMs when scheduling tight connections.

The announcement comes amid intensifying competition: Stansted has secured approval to lift its passenger cap to 51 million annually, and Gatwick’s second-runway project is advancing. Heathrow’s management insists the investment will safeguard the hub’s status as the UK’s global gateway, supporting an estimated 10,000 supply-chain jobs.
