For a commute of 70 miles, the true airspeed of the plane is not a
significant factor. Most of your time will be spent getting to/from
the airport, handling fueling, preflighting, etc.


A dozen or so years ago I was working temporarily in San Bernardino,
while living in Santa Barbara. I looked into using my plane for
commuting (and even tried it once). I concluded that it just wasn't
worth it over so short a distance (in spite of having to cross the
L.A. basin). The difference in door-to-door time was about half an
hour. One problem was that the S.B. airport was 15 miles in the wrong
direction from my house. Another was that I was going East in the
morning and West in the evening (sun in the face both ways). Now, if I
had lived on (or near) one airport and worked on (or near) another, it
would have been a different matter.
