This week's episode takes on the complex task of reconnecting global air travel with Dirk Singer, Research Director of SimpliFlying, an aviation marketing and solutions firm founded by Canada-based Singaporean Shashank Nigam. From his London base, Dirk discusses the white-hot aviation, airline, airport, travel and tourism issues that are confounding policymakers in Europe, North, Central and South America, the Middle East, Africa and Asia Pacific. Will vaccines eliminate the need for quarantines - and, if so, when? Can Green Zone travel actually work? How will vaccine passports be issued and accepted worldwide? What is a Vaccine Hierarchy and why does it matter? What are the specific challenges for intercontinental air hubs like Singapore, Hong Kong and Dubai? Will European borders reopen this summer? What is the 50:50 Trigger? And, will the lessons of COVID-19 enable airlines to future-proof themselves against 'the next pandemic'? Fascinating stuff.
