‘Any proposal that puts recovery at risk should be discounted’ / Montreal, 26 February 2021 – In a letter to the editor in response to the Leader entitled ‘Time to end duty-free’ (27/02/21) published in The Economist this week, Airports Council International (ACI) World Director General Luis Felipe de Oliveira wrote:“In an increasingly competitive and sophisticated market, the revenue generated by tax free sales are an integral part of airports’ non-aeronautical revenues. These activities not only contribute to the health and vibrancy of the airport business and support millions of jobs, but they also underpin the development of infrastructure to facilitate growth in crucial global connectivity.
