I did my first RT yesterday, STL-DAL-STL. The trip down was uneventful. I went to the ladies' room, then came back to the gate, showed my passport and got my boarding pass. No comment from the GA. When I reboarded one of the FAs noticed I had just been on the flight down. I told her I was Mileage running, and she just laughed.
The trip back to STL had more kids than a day care center, I was very grateful for my Bose headphones. It was a WN like crowd. I am losing my resolve not tu upgrade on these runs.
Today I meet aviationkiwi and friends in the STL AC for my second trip. Same itinerary.
