[This article will be updated as the COVID-19 situation and travel information changes between Singapore and Hong Kong. Last updated on 17 May 2021.]

The much-anticipated travel bubble between Singapore and Hong Kong has been put on hold. Both governments agree that this step in necessary to protect travellers’ and public health after Singapore experienced a recent spike in unlinked COVID-19 cases.

The quarantine-free travel bubble was supposed to start on 26 May 2021 but is now being delayed for the second time. In November 2020, the first attempt at launching the travel bubble was unsuccessful when Hong Kong experienced a surge in COVID-19 cases.

On 26 April 2021, when the travel bubble was announced again, there had only been a handful of locally-transmitted infections in Singapore since November 2020. In the recent weeks, however, the number of daily infections have increased.

Singapore’s government and people have been swift in managing the spread of COVID-19 in the past year, with its highest daily average reported in April last year. Meanwhile, the [email protected] facility is also an important effort by Singapore to reopen its borders for business travel in a safe and controlled manner. [email protected] is the first facility of its kind in the world and the first phase of the development opened in February 2021.

Are you looking to travel to Singapore from Hong Kong, or the other way round soon? Here is all you need to know about the Air Travel Bubble (ATB) arrangement.

Who is eligible to enter Singapore from Hong Kong?

Under the Air Travel Bubble (ATB) arrangement, foreigners who are short-term visitors may seek entry into Singapore by applying for an Air Travel Pass (ATP). If you are a Singaporean Citizen, Permanent Resident (PR) or Long-term Pass holder, you are not required to apply for an ATP.

Singaporean citizens and residents may enter via the returning citizen and PR lanes. Long-term Pass holders, however, should seek entry approval depending on their pass type (Work Pass Holder, Student’s Pass or the SC/PR Familial Ties Lane).

Under the Air Travel Bubble (ATB) agreement, only those who have remained in Singapore or Hong Kong in the last 14 days before travel are eligible. This 14-day period does not include compulsory quarantine in Hong Kong or Stay-Home Notice in Singapore. 

Travellers are also required to monitor their health status before departure to Singapore. You should not travel to Singapore if you:

  • Have symptoms of COVID 19 – which include a fever above 37.5°C, cough, sore throat, loss of taste and smell, and other symptoms
  • Are diagnosed or suspected to have COVID-19 in the last 21 days before departing to Singapore
  • Had close contact with anyone with COVID-19 in the last 14 days before departing to Singapore 

What is the criteria for suspension of the Air Travel Bubble?

If the 7-day moving average of daily unlinked cases in Singapore or Hong Kong exceed 5, the air travel bubble will be suspended for at least 14 days, says the Civil Aviation Authority of Singapore. The suspension will take effect in 2 days. The air travel bubble can resume the next day if:

  • The 7-day moving average of daily unlinked cases in both countries do not exceed 5; and
  • There are 3 consecutive days where the daily number of unlinked local cases does not exceed 3 in both countries (the 7-day moving average of daily number of unlinked cases on the last day of the 3 days does not exceed 5)

How to apply for an Air Travel Pass to Singapore?

If you are a foreigner planning a short-term visit to Singapore, you can apply for an ATP here at no charge. Applications must be submitted between 7 and 30 days before your intended date of entry into Singapore. 

Once your ATP application is approved, you will receive an Entry Approval Letter via email. Your ATP is valid for single entry into Singapore anytime from your intended date of entry and up to 7 calendar days after.

For visitors who require a visa for travel to Singapore, you must separately obtain a valid visa after your ATP is approved and before boarding your flight to Singapore. You may check the validity of your visa here
