Heathrow's £1.3bn Terminal 4 Overhaul and AI Investment

Heathrow Airport has announced a £1.3 billion upgrade programme, set to begin in 2026 and complete by 2031. The investment will include a new multi-storey car park for Terminal 4 and a major refurbishment of its check-in area.

Terminal 2 will receive a new baggage system capable of handling 31,000 bags per day, reducing misconnected luggage. Additionally, AI-powered cameras will be installed across aircraft stands by the end of next year to speed up turnaround times.

Heathrow CEO Thomas Woldbye said: “Passengers should expect that every time they travel through Heathrow their journey is better than the last. We’re the most punctual hub in Europe, almost 99 per cent of bags travelled on expected flights and 97 per cent of security queue times were below 5 minutes.”
