Global airlines urged the G7 rich nations on Wednesday to agree to use more flexible data-based methods when deciding whether to keep borders closed in response to COVID-19, rather than maintaining blanket rules that disrupt travel. The head of the International Air Transport Association, Willie Walsh, told an online briefing governments across the world should let airlines and travellers assess the risks of travel based on freely available data. The former British Airways head also said he was confident Europe could begin to return to normal travel in the second half of the year.
