Singapore announced on Tuesday it will open a segregated travel lane so "business, official, and high economic value travelers" can visit the city-state quarantine-free by staying in a designated "bubble" facility near the airport.

The facility, Connect@Changi, will feature guest rooms and conference rooms where visitors can meet with other people staying in the bubble. Travel lane visitors will be able to meet with Singapore residents in the bubble—but only with floor-to-ceiling dividers separating them.

The business travel lane is the latest attempt by Singapore's government to jump-start the country's all-important tourism and business travel sectors, which have cratered in the COVID-19 pandemic.

Tourism accounts for 4% of Singapore's gross domestic product—it generated $20 billion in 2019—and the city is normally a top spot for business conferences and trade shows.

Over 19 million international tourists—more than three times the population of the country—visited Singapore in all of 2019, according to the Singapore Tourism Analytics Network. Through October, just 2.7 million visitors had trickled across the border in 2020.

Singapore largely has its coronavirus outbreak under control; it has not logged more than 20 new daily cases since the end of September. But its small size—the island nation spans 280 square miles—means that unlike its geographically bigger Asian peers that have also tamed COVID-19, Singapore can't rely on domestic tourism to make up for the steep drop-off in international visitors.

"We don't have a big domestic tourism market unlike, say, the Chinese mainland or Hong Kong or Australia, and so the impact has been tremendous on our tourism industry," Keith Tan, chief executive of the Singapore Tourism Board, said during a Fortune Global Tech Forum virtual conversation earlier this month.

In desperate bids to revive tourism and business travel, Singapore has rolled out a series of schemes—with varying degrees of success.

Domestic tourism

In June, as Singapore was loosening stay-at-home orders and other COVID-19 restrictions, the Singapore Tourism Board started letting popular tourist attractions reopen in stages and began accepting applications from domestic tour operators to resume business.

The following month, the board launched SingapoRediscovers, a $34 million campaign to boost local tourism, offering residents "staycation" packages, tours, and discounted attractions. That campaign included a $75 voucher for every adult Singaporean to use on hotels and attractions. On Dec. 1, the first day the vouchers were redeemable, the designated booking platforms received $1.4 million in sales.

Singapore's flagship carrier, Singapore Airlines, has also staged creative attempts to boost revenue and get some of its planes back in the air. (In October, it recorded a 98.2% year-on-year decrease in passengers carried.)

The airline toyed with the idea of “flights to nowhere.” Passengers would board a plane that took off from Singapore's Changi Airport, fly around, and then land at Changi again. Airlines in Taiwan and Hong Kong have operated flights to nowhere, with some working better than others. The haze over Hong Kong on the day of the region's inaugural flight to nowhere was so thick that passengers couldn't see the city from the plane.

Singapore Airlines ultimately didn't follow through on the flights to nowhere idea, opting instead in October for a grounded experience that offered customers dinner and a movie on a double-decker A380 plane for $37 to $440. The airline also began offering tours of its training center and use of its flight simulator.

Singapore did allow the Royal Caribbean cruise line to launch "cruises to nowhere" from its harbor, but last week one ill-fated ship returned to port a day early after a passenger tested positive for the coronavirus, despite upgraded air filters, mandatory testing, and other safety protocols that officials had required of the operator. (It's still unclear when or where the passenger contracted the virus.)

Bubbles and lanes

In September, the city-state received the first passengers from Brunei and New Zealand under its Air Travel Pass program.

The scheme lets visitors—including leisure tourists—apply to travel to Singapore and do so without undergoing a 14-day quarantine. Since it launched the plan in September, Singapore has expanded the list of eligible regions to include Australia, China, Taiwan, and Vietnam. The scheme is unilateral, meaning Singaporeans who want to travel to those countries are still subject to existing coronavirus travel restrictions.

Singapore also runs reciprocal "green lane" programs with China, South Korea, Indonesia, Malaysia, Japan, Brunei, and Germany that let some corporate and diplomatic travelers skip quarantine on arrival if they test negative for COVID-19.

But Singapore still hasn't managed to open a travel bubble with another region that would allow tourists from both sides to travel back and forth without quarantining.

In late November, it very nearly pulled off a travel bubble with Hong Kong that would have let residents of each region travel quarantine-free to the other, but a fourth wave of coronavirus cases in Hong Kong thwarted the bubble and forced authorities to delay it until at least 2021.

Conference hopes

Singapore's various travel schemes provide an immediate boost to struggling hospitality businesses, but they are also attempts to establish Singapore as a place that is safe and open to visitors. Such a reputation would bolster the city-state's chances of playing host to global conferences and events as COVID-19 vaccines become available and the pandemic eases in 2021.

The "MICE industry"—meetings, incentives, conventions, and exhibitions—supported more than 34,000 jobs in Singapore and contributed $2.9 billion to the economy in 2019, according to the tourism board.

The World Economic Forum announced earlier this month that it would hold its annual meeting in Singapore instead of Davos, Switzerland. The gathering of business and political elites is scheduled for May. If it takes place successfully, it will be a boon for Singapore's economy and a clear indication that the city can host large global events without risking coronavirus transmission.

But Singapore no doubt is haunted by a worst-case conference scenario it experienced early in the pandemic.

In late January, when Singapore had the third-highest number of confirmed coronavirus infections in the world (which, at the time, meant 43 cases), a British man contracted COVID-19 while attending a business conference in Singapore. The man traveled back to Europe, where he infected several other people. The media dubbed the Singapore conference a "super-spreader event."

Singapore's current control over local coronavirus infections supports the city's argument that it can host global events like WEF's annual meeting next year. But its handling of the virus was far from perfect. Singapore's government said on Tuesday that half of the city's migrant workers have had COVID-19.

Authorities used serology tests to detect antibodies, indicating past infection, and found that 98,289 workers had them. The government is still completing serology tests for 65,000 more workers. The results indicate that Singapore's case count is far higher than the official tally of roughly 58,000.
