British Airways’ offering gives travellers information at a glance, by simply swiping the watch face to receive notifications of departure time and flight status.
A further swipe will deliver more detailed information including flight number, route, weather and connecting flights.
Other advantages proffered to Watch wearers include check-in and gate notifications, as well as welcome messages and wi-fi codes for those arriving at the lounges within Heathrow Terminal 5.
Sara Dunham, British Airways’ head of marketing, retail and direct channels, said:
“We’re excited to be one of the first apps available for Apple Watch.
We know our customers love innovation and we love making travel through the airport as quick and easy as possible for them, so this is the perfect combination.
With a quick look at their wrist, the glance screen will deliver them everything they need to know about their upcoming flight.”
A sister app will also be launched by Avios, the travel rewards currency offered by BA, allowing particiapants to easily keep tabs on their balance.
