The travel industry is suffering its worst shock since 9/11 because of coronavirus

It's one of the largest industries in the world, with US$5.7t in revenue. It is responsible for an estimated 319m jobs, or roughly one in 10 people working on the planet. And no sector is more at risk from the novel coronavirus. The travel industry has already taken a huge hit due to travel restrictions and cancelled trips for both business and pleasure, but that's just the beginning. It could be the worst crisis for the industry since the September 11 terrorist attacks on the US, according to some experts. "It's on the front line of the fallout," said Mark Zandi, chief economist with Moody's Analytics. "It's the most directly and immediately impacted." "If you measure the entirely of the impact of travel, it is bigger than any other industry around the world. No other industry can say it supports 1 in 10 jobs," said Adam Sacks, president of Tourism Economics. "It's partly because it's such a diverse industry. It includes a lot of things you don't think of. Besides airlines and hotels, it's part of retail, part of restaurants, parts of technology."<br/>
