It wasn't until my mid 20s in July 2006 I flew DSM-PHX on a US CRJ900. The flight wasn't bad at all (had exit row) except for right after take off we took what felt like a hard left and I felt a little queasy. After getting a couple more flights under my belt that rarely happens now though a couple years later on a flight from OMA to PHX that had constant turbulence from climb out to landing was the closest I've ever come to losing it. Another 20 or so minutes and things wouldn't have ended well.
