If you include this extra time on the tarmac, the average total elapsed time from gate to gate flying from Los Angeles, CA to Atlanta, GA is 4 hours, 14 minutes.
Knowing the above, and that it takes about 5 hours to fly from NYC area to Los Angeles (It takes a bit less going the other way as the wind blows from West to East.). And about 5 hours from Los Angeles to Hawaii (With the same caveat for flying back.). This puts the entire flight time at about 10 hours. Not including lay-overs and plane changes.
