the new boarding pass showed 25F - which I didn't notice untill the attendent read it. My original boarding pass, which I printed out 24 hours before departure time clearly showed seat 1A.....for which I paid the upgrade fee. I will watch for activity on my credit card.

If I was a "bad guy", I could have taken out the pilot since he and I were face to face with no one else around. Poor security if you ask me.

I think Frontiers gate attendants at Greenville need some additional training
