I wish I had the data! Likewise, collecting the number of passengers carried would be a nice cumulative statistic at the end of my career (I guess I can start recording this when I become a Captain?)
You could (probably) pull the ADSB data for a "representative" flight on given routes and use that to at least get close - probably would still be useful for things like radiation exposure mentioned elsewhere.
Otherwise, maybe you can get Claude to vibe code you a mobile app that runs in the background and collects all the interesting data (GPS, cabin alt, etc)
