Markus Svensson, Qantas regional general manager UK, Europe, Middle East and Africa said the pop-up also celebrates the exciting new era for Qantas in the UK, including its new non-stop London to Perth flights.
Svensson said: "Australia Day is all about celebrating the best of Australia, no matter where you are in the world. When London to Perth flights launch next year, UK travellers will be able to experience Australia firsthand with our non-stop services. But today, Qantas and Heathrow are bringing the Aussie summer to them."
Jonathan Coen, Heathrow’s customer services Director said: "We are delighted to give passengers a ‘warm’ Aussie welcome to Terminal 3 on this chilly January day. We have had a fantastic year working with Qantas celebrating our birthday and hearing all the exciting stories from passengers travelling with us. Here’s to the next 70 years of stories."
