Nice metrics and visualizations! The kind of graph you used for the destination matrix doesn't always feel very useful, but in this case it worked really well.

One thing I immediately thought to check after seeing your hours graph was what percentage of the year you were in flight (or in a plane, I guess). For your peak year (2024), it worked out to be about 8.7% of the year! It probably even higher if you just count your waking hours, but I don't know your sleep habits or how many of your flights you might have slept during.
