Bought a ticket at the counter earlier this week. The DEN-LAX airfare portion was $3.72 r/t hah! $32.40 w/ taxes. The ticket agent said she had seen the fares earlier in the morning and bought one herself. She didn't seem to understand why the prices were cheaper at the airport so I explained the CIC. She applauded me for being clever.
She gave me a seat without me asking. It was a window in the way back, I almost certainly would have gotten a better seat if I just waited until checkin. At least it wasn't a middle, then I think I would have been forced to pay to move out to another seat, gah!
