The man accused of slapping a crying 19-month-old on a plane earlier this year has pleaded guilty to assault in federal court.
Joe Rickey Hundley is facing six months in prison.
Hundley's attorney has said Hundley was in distress and grieving during the flight after learning the day before that his son was in a coma.
He was headed to Atlanta to decide whether or not to take his son off life support.
Hundley, who's also accused of using a racial slur in the incident, will be sentenced in January.
