Airlines should not charge extra money to assign seats for children under 12 years old.

Airlines charge extra fee for assigned seat for children, other wise children get random separate seats from parents. There should be a law to protect children to sit next to possible criminals or sex offenders. We should not pay extra to protect our kids. Extra fees that are charged by airlines are getting out of control.
Assigned seat for children under 12 should be free and automatic next to their parents.
