Just enjoy the CCR, have a nice meal, get to the gate and enjoy the devil out of the left turn!!! As you enter the aircraft, they'll ask for your boarding pass and will escort you to your seats and that's a good time to say something about being excited to be in F for the first time. Ask the crew to take a minute to show you the handsets, etc. and that will also clue them that you are on your first, first trip. Now, I made that mistake (turning left, flying first) once about 15 years ago and it's very addictive!!!! Haven't turned right since.
