Former Alaska Airlines pilot Joseph David Emerson was sentenced to time served and three years of supervised release on the federal charge of interfering with a flight crew.

Emerson previously reached a plea deal in state court in September 2025, where he pleaded no contest to 83 counts of endangering another person and one count of endangering an aircraft. For those state charges, he received:
Five years of probation
Credit for the 50 days he spent in jail
664 hours of community service
Approximately $60,000 in restitution, primarily to the airline
