He hasn’t been convicted of anything yet.
The headline on this is pretty awful, honestly. He was arrested for battery on crew (throwing ice at them) and disruption of the flight, not for the homophobia.
This headline is a right wing pundit’s dream. “20 years in prison for saying a bad word! The left gone power mad” and so on. Of course, that’s not actually what happened. “So and so faces X years” has to be one of the worst boilerplate headline formats we have in this world. It doesn’t mean anything.
