British Airways says AI tools have saved over 400,000 minutes of delay at Heathrow
British Airways says AI tools for stand allocation and weather rerouting have saved more than 400,000 minutes of delay, and a disruption tool has modelled 163 scenarios. In the first quarter of 2025, 86% of its Heathrow (LHR) flights left on time, a record. The figures are the airline's own.

British Airways operates up to 800 flights a day at Heathrow, by its own count. In 2023 it began a £7bn investment programme, including £100m for operational resilience, 600 extra operational roles at Heathrow and more than 100 data scientists, the airline said in May 2025.
Its AI work at the airport goes back to 2019, when it trialled Assaia's camera monitoring of turnarounds at Terminal 5.

The work behind the evidence
01 / Deployed
Four tools for the day of operation
The operational problem
At a full hub, a late arrival, a poor stand choice or a band of weather can cascade into missed connections and late departures across the day.
What the evidence reports
British Airways said on 14 May 2025 that a stand allocation tool assigns arriving aircraft at LHR using live analysis of passengers' onward connections, saving 160,000 minutes of delay. A weather tool reroutes aircraft around poor weather in coordination with European air traffic flow centres, preventing 243,000 minutes of delay. A predictive tool flags routes likely to face delays, and the Runway tool uses schedule, passenger and crew data to recommend responses to disruption; it modelled 163 scenarios across 2024 and 2025. Chief executive Sean Doyle said: "The tech colleagues have at their fingertips has been a real gamechanger for performance."
Operational significance
These tools sit where delay is created and recovered, in stand planning, routing and disruption response, and BA attaches minutes saved to each.
Evidence still needed
The figures are British Airways' own and have not been independently verified. BA has not said how the minutes saved are calculated or how much of the punctuality record the tools account for, alongside extra staff and other investment.

02 / Pilot
An early camera trial at Terminal 5
The operational problem
Turnaround tasks such as cleaning and catering were checked manually, so a task running late was often noticed only when the departure slipped.
What the evidence reports
Airport Technology reported in November 2019 that British Airways was trialling Assaia's system on three stands at Terminal 5, with four cameras. Neural networks compared the planned schedule with live footage of 18 turnaround activities and alerted managers by smartwatch when an issue could delay departure. Raghbir Pattar, director of airports, said efficient turnarounds were critical for an operation of up to 800 daily flights.
Operational significance
The trial was an early airline test of computer vision on the turnaround, a use that has since spread to many airports.
Evidence still needed
The trial has ended. British Airways has not published its results or said whether the system was adopted.

15below passenger notifications at British Airways · Deployed · limited scope
During the Heathrow shutdown, British Airways alone sent more than 120,000 notifications through the 15below platform between midnight and 8am, 15below wrote in a blog post on 25 March 2025.

Editorial assessment
British Airways has put AI into the daily running of its Heathrow operation, and has published more operational figures for it than most airlines.
An independent measure of the tools' contribution, separate from the wider £7bn programme, would show how much of the record is down to AI.
