I’m doing an about-turn again – I’m staying put.
The risk of being stranded at a transit airport ( e.g. KUL, Malaysia ) isn’t one I want to take.
Also, if I had returned to NZ, I would have arrived after lockdown, and thus been forced to do 14 days self-isolation at the airport of arrival – Auckland.
This may come as a surprise, but Vietnam is safer than NZ when it comes to catching the lurgi – https://www.worldometers.info/coronavirus/.
I’m now busy scrambling about doing what I can to secure airline credits and refunds for the booked flights.
