While reporting its latest traffic volume figures today, Heathrow airport CEO, John Holland-Kaye, looked back on an "incredibly challenging" year for aviation. Holland-Kaye added: "The aviation industry is the cornerstone of the UK economy but is fighting for survival. We need a road map out of this lockdown, and a full waiver of business rates. This is an opportunity for the government to show leadership in creating a Common International Standard for pre-departure testing that will allow travel and trade to restart safely so that we can start to deliver the Prime Minister’s vision of a Global Britain.” As this infographic shows, the UK's biggest commercial transport hub saw decreases in passenger traffic of over 80 percent in 2020 when compared to 2019.
