Some very strange patterns to be seen
It is difficult to make much sense of the graph without having some calibration with respect to days of the week and time.
Sure; the bit I notice is how the weekly periodicity, which was constant since 2012, disappeared. Obviously due to different working patterns.
Yes, this is clear and your analysis makes very good sense.
In August (when Covid-19 numbers were low), the periodicity seems to have returned for a short time, then it disappeared again.
It seems to be up slightly on recent months. I am pleased, looking at how few people are doing any flying at all…
We are still not really seeing the usual weekday/weekend pattern which was so constant for the previous ~8 years.
The weekly cyclic activity is sort of returning, but clearly much less pronounced
The improvement continues, according to the undisputable economic barometer here
The weekday/weekend difference remains small, however.
I reckon there has been a permanent change in general activity, but what? It still looks like many are working at home
The above is 31 Jan 2020, up to today.
I don’t think those who read EuroGA are ever going to get back to the office
