Did president nixon take commerical airline flight while president

Question

Did President Nixon take an unannounced commercial flight while in office?

Answer 1

Good question.  I don't believe he did, but there are pictures of him hobnobbing with what you think are ordinary passengers inside an airline cabin.  Those were actually reporters in their area of Air Force One.  

Answer 2

Yes, he did. In 1973 he took a commercial flight from D.C. to Los Angeles. But, Air Forse One flew behind the plane.
