A California man who wanted more nuts and other in-flight snacks was behind a Chicago-bound United Airlines flight that was forced to divert to Northern Ireland .
Almost 300 United Airlines passengers slept on an airport floor overnight after their flight from Rome to Chicago was diverted to offload a disruptive passenger late Saturday.
Their ordeal began when Flight UA971 made an unscheduled landing in Belfast, Northern Ireland, where a passenger was arrested.
The Boeing 777 landed at 6.59 p.m. local time (1.59 p.m. ET) Saturday and was refueled but flight crew reached FAA working hour limits before the journey could resume.
