Drunk airline passenger Michael Fellows caused havoc aboard a flight from Norway to Newcastle.
Fellows put the Eastern Airways flight in danger by lighting up a cigarette and ignoring the instructions of crew members.
Newcastle Crown Court heard Fellows had been working in Norway and had not consumed much alcohol because it was £15 a pint.
So once he was on his way home he decided to make up for lost time and had a bottle of vodka with him on the plane.
Now Fellows, 43, has been warned he may face a custodial sentence after he admitted endangering the safety of an aircraft and being drunk on an aircraft.
Judge Jeremy Freedman told him: “I regard it as a serious offence and you must appreciate it could well be met by a custodial sentence.”
Fellows will be sentenced later this month and was granted bail in the meantime.
Full details of the offences were not outlined during the brief hearing.
However Fellows admitted endangering flight 4802 and other passengers on March 14 this year.
His bad behaviour included smoking on the plane, interfering with crew members, behaving in a disorderly manner and ignoring instructions from staff.
Fellows also admitted a second charge of being drunk on the same flight.
His barrister said he had just finished a ten week stint working in Norway and was not able to drink much due to the prices.
Sentence was acjourned while pre-sentence reports are compiled on Fellows.
