A travel bubble between Hong Kong and Singapore, originally slated to begin on 22 November, has now been postponed amid a spike in infections in Hong Kong. The air travel bubble, meant to boost tourism for both cities, will be delayed by at least two weeks, Hong Kong’s minister of commerce and economic development, Edward Yau, said at a news conference.

The arrangement is meant to allow travellers between the two cities to enter without quarantine as long as they complete coronavirus tests before and after arriving at their destinations and fly on designated flights. Hong Kong reported 43 new coronavirus cases on 21 November, including 13 untraceable local infections.

“For any scheme to be successful, they must fulfil the condition of securing public health and also make sure that both sides would be comfortable and feel safe about the scheme,” Yau said. “In light of the situation in Hong Kong, I think it’s the responsible way to put this back for a while, and then sort of relaunch it at a suitable juncture.”

The plan will be revisited in December, he added.

Under the initial agreement, the travel bubble was to be suspended if the number of untraceable local infections in either Singapore or Hong Kong exceeded five on a seven-day moving average. The current average in Hong Kong is nearly four, prompting Yau and Singapore’s minister for transport Ong Ye Kung to postpone the inaugural flight.

Hong Kong has confirmed a total of 5,561 cases, including 108 deaths. Singapore has reported 58,148 cases, but only 28 fatalities.

Prior to the postponement, Singapore had said that travellers arriving from Hong Kong via the bubble would be required to take a coronavirus test on arrival. Originally, only people landing in Hong Kong were to be required to be tested.
