A Florida man (isn't it always a Florida man) was busted and banned for life for vaping on a Spirit Airlines flight this week. 

He was spotted by a flight attended chuffing at his seat, asked to stop, then went and set off the smoke detector in the lavatory.

He was stopped but not arrested by a deputy upon landing in New Orleans.
