Live flight status information, gate updates and details on arrivals and departures is being made available via voice-based Amazon Alexa.
Users of Alexa devices will be able to access information on around 1,300 aircraft movements a day by 84 airlines.
The Alexa Skill draws on the data within Heathrow’s own flight information data hub, which collates all flight schedule information.
Heathrow’s new Skill has to understand queries related to multiple carriers and interpret alphanumeric codes.
Travellers will now be able to use Alexa alongside the Heathrow website and mobile application to access consistent flight data 24 hours a day.
The airport’s digital manager Stephen Glenfield said: “Delivering detailed flight information directly to customers within their homes is another fantastic milestone in improving our digital experience.
“Launching the first airport-specific Alexa Skill in the UK ensures easy access to the latest flight information, helping passengers to plan their journey more effectively and improve their experience from start to finish”
