A long-delayed travel bubble between Hong Kong and Singapore will begin on May 26 as the two cities move to re-establish overseas travel links and lift the hurdle of quarantine for visiting foreigners.

The bubble between the two Asian financial hubs had been slated to begin last November but was suspended after a spike in coronavirus cases in Hong Kong.

The scheme will start with one flight a day into each city, with up to 200 travellers on each flight, Hong Kong’s Commerce Secretary Edward Yau and Singapore’s Transport Minister Ong Ye Kung said at simultaneous press events on Monday.

Those wanting to travel from either city must test negative for COVID-19 before departure and on arrival.

Hong Kong residents can also only fly to Singapore at least 14 days after they have had two doses of COVID-19 vaccine.

Travellers won’t have to quarantine and there will be no restrictions on the purpose of travel.

However if the seven-day moving average of the daily number of unlinked local COVID-19 cases is more than five for either Singapore or Hong Kong the scheme will be suspended, Mr Yau and Mr Ong said.

“The relaunch … signifies that gradual resumption of cross-border travel is achievable through mutual collaborations among different places,” Mr Yau said.

For Hong Kong, which has banned non-residents since March 2020, the deal with Singapore is its first bilateral resumption of travel ties with another city.

Singapore already has some pacts on essential business and official travel, and has opened unilaterally to general visitors from countries including Brunei Darussalam, China and New Zealand.

Singapore has also been discussing an air travel bubble with Australia.

Both Hong Kong and Singapore have brought the local virus situation largely under control compared with other developed cities.

New cases, however, have inched up in the past week, with Hong Kong reporting local transmission of a COVID-19 variant with the N501Y mutated strain and Singapore investigating possible COVID-19 reinfection cases at a migrant worker dormitory.

The dormitories were at the centre of Singapore’s outbreak in 2020, with thousands of cases.
