 An intoxicated passenger threatened to hang himself in the airplane bathroom on Christmas day. 

 A man flying to New York on Christmas locked himself in a Jet­Blue plane bathroom and threatened to hang himself, authorities said.

The passenger, 37, was drunk and said he would use his belt to commit suicide on Flight 168 from Oakland.

The plane landed at JFK Airport at 7:20 a.m., and Port Authority cops took the uninjured man off the flight 20 minutes later, a spokesman said.
