"Imagine needing an airline to tell you to use headphones and have basic courtesy and respect for other people in public
There are a lot of clueless people out there.
A major U.S. airline is warning they can now be kicked off for “barebeating” – one of the most annoying in-flight habits. Anyone who travels frequently has likely encountered at least one nightmare passenger. There are the people who cut security lines (“gate lice”), travelers who refuse to calm a screaming child during a long flight, and the particularly unpleasant offenders who stretch their feet into someone else’s space between the seats.
Yet another behavior has increasingly become one of the most complained-about annoyances in the air – passengers playing music, videos, or games out loud on their phones.
The habit has even earned its own nickname: “barebeating.” The term refers to people who listen to audio directly from their device without headphones, forcing everyone around them to hear it.While it may not be as shocking as some other in-flight behavior, it can quickly ruin a quiet cabin environment.
