Some parenting plans require the parents to fly the children back and forth between two distant places.  What some people do not realize before they start shopping for the cheapest fare is the fact that different airlines charge different fees for minor children to fly without an adult chaperone.  This chart has the unaccompanied minor fee each way for all major domestic airlines in the United States.  It is accurate as of November 27, 2017.

As you can see, Alaska and Southwest are the least expensive.  Unfortunately, Alaska’s service is a little limited for the Sacramento area, and Southwest often has connections between origin and destination cities.
