The Singapore-Hong Kong Air Travel Bubble kicks off on Sunday 22 November, but concerns are resurfacing across Asia about volatile new COVID-19 waves. Soon after the ATB was launched, Asia's media was rife with speculation about which other countries might launch travel bubbles - either with or without Singapore and Hong Kong. But they seem no nearer to fruition. This week, Gary and Hannah scan the region for signs of travel bubble activity, and report the latest from Australia and New Zealand where hopes for a two-way bubble in 2020 are starting to recede. Plus, there's news of a 'private' travel bubble between Qatar and Maldives, and an assessment of the long-mooted ASEAN Travel Corridor. Will it ever happen?
