Business dried up to almost nothing. Now, with vaccination campaigns beginning to pick up speed, plans around travel bubbles falling in place and discussions around vaccination certificates proliferating, there is hope for a big rebound that will supercharge the moribund industry. The year 2019 saw almost 2 billion international tourism departures around the world. But that number evaporated in 2020, even for domestic travel. The World Economic Forum estimates the travel industry lost $1.3 trillion in 2020. According to the United Nations World Tourism Organization, or UNWTO, 1 billion fewer international arrivals were recorded in 2020 than in 2019, a plummet of 74 percent. Even during the global crisis of 2009, the decline was just 4 percent. Malaysia recorded just 4.22 million tourist arrivals in 2020, down from 26.1 million in 2019, while tourism revenues fell 85 percent. Thailand lost 40 million tourists and experienced the worst economic downturn since the Asian financial crisis of 1997. Foreign arrivals in Vietnam fell 79 percent to just 3.8 million, according to the General Statistics Office. The plunging numbers have forced the industry to adapt. Singapore's Blue Sky Escapes is a good example of how the adaptation is playing out. Blue Sky specialized in outbound journeys but had to shift its offerings as COVID-19 hit in February 2020.
