The retailer will open a 3,600 sq ft shop at the new terminal, on the top floor of the departure lounge. The plans include the creation of around 40 new jobs.
Andy Street, managing director, John Lewis said: “This new opening is a huge and exciting step forward in developing our international strategy, giving us access to one of the most concentrated, valuable and influential markets in the world. We recently made clear our ambition to further develop our online presence internationally in addition to increasing our international wholesale business. This opportunity at Heathrow perfectly complements and enhances these initiatives.”
