> To be honest, I'm confused by the amount of air travel that is still going on. If locking down large swathes of most countries is on the cards, why is there any air travel happening?

I think essentially all the data we have indicates that there is a surprisingly low rate covid transmission on airplanes and airports. (You can be worried that the data is being provided by airline companies who are biased, but at this point I think you have to postulate a pretty big conspiracy in order to explain the consistent signal.) Assuming that's true, it means:

1. Your concern should be with any method of travel, not air travel per se.

2. Your concern should be with travel between areas with very different rates of covid (or of different variants), not travel in general. If an infected person in country A swaps places (through flight) with an infected person in country B, nothing has changed regarding covid transmission.

Absolutely. But the article (via footnote 12) is talking about how there are variants of Indian origin being detected in the UK. There is the paragraph:

> Two more cases of the Variant of Concern VOC-21JAN-02 (P.1) have been identified in England – one in the West Midlands and one in Haringey, London.

When the varient crosses a border, it is highly likely it will cross by plane or boat. The worst case outcome is mass lockdowns. I have some faith that it is easier to detect COVID on sea voyages because it is slower and I assume less volume of people, but air travel is a different story. What are the risk-rewards of this air travel?

In 2020 I faced things like being forbidden from leaving my home & my parents potentially dying (they didn't). These were issues faced on a mass scale. I'd like to know how important all this globetrotting is relative to those pain points.

I suppose I'm open to shutting down passenger travel by boat if the numbers are there.

The U.S. was extremely slow to restrict travel from India. Are many people traveling to the U.S. from India via car, bus, train, or boat? Flights are the concern because that's how people travel between continents.
