Absolutely...I remember my first time alone. It was waaaaaay back in 1994, and I flew DL IAH-DFW-BTR to take some CLEP exams at LSU, where I was accepted to attend college at the time..before I moved on to Texas A&M. It was great, and I felt like I was a high roller at 17.
The best part was that I smiled and acted dumb (which I was....errr....still am) to the DL agent in BTR, and she upgraded me to FC for the BTR-DFW segment! Talk about beginner's luck as a non-elite! Only other time this happened to me was on MSY-IAH on the flight that I qualified for CO silver for the first time back in 2001.
Ah, memories!
