The flight was from Las Vegas in Nevada to Hawaii but was diverted to Los Angeles airport because of the passenger's antics.
He voluntarily left the flight when it landed in Los Angeles and caught another, Rob Pedregon, a spokesman for the Los Angeles airport police told AFP news agency. The employee informed the man there was a $12 fee for a blanket and he became angry.
Los Angeles Airport Police and the Federal Bureau of Investigation met the aircraft at the gate.
Though officials say no "credible threat" was made, the flight crew's discomfort led them to alert the captain.
He was allowed to book another flight to his destination. "Maybe they felt uncomfortable with it, which is well within their rights to divert the plane and refuse service", Pedregon said.
"You know, if I was a passenger on board that plane I would have paid the $12 dollars for him", he added.
The pilot was forced to divert to Los Angeles after the man's "threatening behavior". "I'm going to call the president", Enriques said.
Four hours later, the plane was back in the sky.
"(The crew) took offence to the statement that he made.
Passenger Claudia Rodriguez, a Dallas resident, said the airline did not provide much information during the incident.
A flight attendant told Enriques that the male passenger in 42A had threatened the pilot, not a flight attendant, Enriques told the Honolulu Star-Advertiser.
Speaking with CBS Los Angeles, traveller Eileen Berstrom said the incident was "ridiculous".
The flight departed Los Angeles a few hours later.
Even so, the airline stuck by its decision to reroute the flight.
