Travel restrictions should be limited, temporary and aimed at slowing the import of new variants, rather than the impossible mission of stopping them
few, the mid-20th century was a golden age of air travel: there was plenty of room and the cabin crew were attentive. Back then foreign trips were glamorous and mass tourism was unknown. Sound familiar?is once again the preserve of a happy few. International tourist arrivals are down by 85% from pre-pandemic days. Nearly a third of the world’s borders remain closed. Many of the remainder are open only to those who have been vaccinated or can afford tests.
Most countries have land borders and voters. For them isolation was never feasible. Instead, they have adopted a confusing, illogical mess of rules. America bars travellers from Britain and the European Union, its closest allies and trade partners, and also two of the most vaccinated big places in the world, while admitting those from South-East Asia, where the Delta variant is rampant. Thailand bans entry from some countries and requires all other travellers to submit to a two-week quarantine.
There is a better way of regulating global travel. The first principle is to default to open borders. This does not mean a free-for-all, but any restrictions should be limited, temporary and aimed at slowing the import of new variants—rather than the impossible mission of stopping it altogether. Once such variants are established in the destination country, as Delta is pretty much everywhere, restrictions are redundant and should be scrapped.
