If any U.S. airline tried this, they'd be hit with 75 lawsuits before the plane even landed.  But apparently, in Iceland, ANYTHING GOES.

A photo has been circulating around of a passenger who was DRUNK and OUT-OF-CONTROL on an Iceland Air flight . . . so the crew DUCT TAPED him to his seat.

The plane was actually headed from Iceland to JFK Airport in New York, and when it landed, the guy was arrested.
