Well not really if he was let go the first time to commit the same offence a second time. All these losers should be deported at first offence and banded for life.
Well of course he should face a lifetime ban. So should every passenger who is abusive or aggressive to staff or other passengers.
People's behaviour is getting worse on flights and rarely do they face any real consequences.
Good luck trying to change the rude habits of that bunch of arrogant, ignorant, belligerent pigs. And the government wonders why they have difficulty attracting “quality tourists”.
