A common myth that flying “big jets” is more”fun” or “passion”; it’s called work for a reason. Fun flying is acro, fighters (not on a war), float planes, etc. Any jet is flown in accordance with strict standards, by the numbers, is watched thru FOQA programs and is regulated by Uncle Sam to the point you can’t start up without a government employee giving you permission.
The people, the trips depending on the people, the travel can be fun; watching an autopilot fly they the dark is work.
