Funny you should mention North America. I’ve been flying mainly UK/EU area, and there is traffic over busy areas, but not as dense as I’d have expected. I did a couple of flights in North America, and suddenly encountered much more. The LIkes of SFO was really busy, Phoenix too. This was on XBox with Live traffic ON. Maybe flightjs in US are still running at a more normal higher frequency in US in the covid era, where as we definitely have a reduction here.
