In an interview with the Press Association news agency, (chief executive of Heathrow) John Holland-Kaye said: "It's just physically impossible to socially distance with any volume of passengers in an airport." He said a "better solution" is needed to make air travel safe. "The constraint is not about how many people you can fit on a plane, it will be how many people you can get through an airport safely."
In a separate interview, with the BBC, Mr Holland-Kaye said that until a coronavirus vaccine could be developed, airports would have to introduce measures to minimise infection once lockdowns started to ease. "This might include some kind of health screening as you come into the terminal so that if you have a high temperature, you may not be allowed to fly," he said. "As you go through the airport, you will probably be wearing a face mask, as people from Asia have been doing ever since Sars (virus) came out."
