He asked for a blanket and was told it would cost $12, the officer said.
Witnesses said he took offence at the price and said he should be allowed to have it for free as it was cold, the NY Daily News reported.
A Hawaiian Airlines flight from Las Vegas to Honolulu was diverted to Los Angeles on Wednesday when a passenger became irate after being told he had to pay $12 for a blanket.
"We had an unruly passenger on board, so the pilot elected to divert to LAX", said Hawaiian Airlines spokesman Alex Da Silva. However, a flight attendant said it was the pilot that the passenger made threatening remarks about.
The man voluntarily abandoned his flight and caught another one.
The man asked to speak with Hawaiian's corporate headquarters and, during that call, he told a company representative, "I would like to take somebody behind the woodshed for this", Pedregon told The Post.
Los Angeles Airport Police and the Federal Bureau of Investigation met the aircraft at a gate on Los Angeles. It landed in Los Angeles at 10:23 a.m.
"(The crew) took offense to the statement that he made.
Hawaiian Airlines spokeswoman Alison Croyle said, "We don't know the demeanor of the passenger, what was said, or the tone".
Croyle said the airline offers complimentary blankets in all cabins on worldwide flights and on certain red-eye flights.
The flight departed Los Angeles a few hours later.
Data from the Flight Radar 24 website shows that the diverted flight later continued on to Honolulu following its unscheduled LA stop.
Even so, the airline stuck by its decision to reroute the flight.
