Struck by the global health crisis, international tourist arrivals to Europe dropped 70% in 2020 over 2019, and it now holds a 58% share of international tourist arrivals worldwide, with Asia Pacific remaining closed to tourism. In early 2021, travel restrictions have been tightened and lockdowns reintroduced across Europe as destinations suffer a third wave of infections.
Despite distribution challenges, the roll-out of vaccines has provided some grounds for optimism for 2021 projections and, together with improved testing regimes, is expected to stimulate consumer confidence and hasten the easing of movement restrictions. Nevertheless, a return to typical international travel demand patterns will be gradual and apparent towards the second half of the year, with 2019 levels only reached fully by 2023.
