Air travel brings people from many backgrounds into a shared space, which means basic courtesy helps keep flights comfortable for everyone. Recently, a major U.S. airline introduced a clearer rule addressing a common complaint from travelers: passengers playing music, videos, or games out loud on their phones without headphones. The behavior—sometimes jokingly called “barebeating” online—can quickly disturb the quiet environment many passengers expect during a flight.

As more travelers stream content on their devices thanks to improved in-flight internet, airlines are paying closer attention to how these small habits affect the overall cabin experience. To address the issue, United Airlines updated its Refusal of Transport policy. The guidelines now state that passengers who refuse to use headphones while playing audio or video may be considered disruptive. In serious cases, this could lead to a passenger being denied boarding or removed from a flight.

The rule places loud device use alongside other disruptive behaviors, such as ignoring crew instructions or boarding while intoxicated. Although headphones have always been expected etiquette on flights, the airline says the rule is now being emphasized as onboard internet services continue expanding. With faster connections available, more passengers are streaming movies, playing games, or listening to music during their trip.

Many travelers have welcomed the update, saying headphone use in shared spaces should already be standard practice. Flight attendants also note that reminding passengers to lower their device volume has become increasingly common. Ultimately, the message from airlines is simple: if you plan to enjoy entertainment on your phone or tablet during a flight, bring headphones so everyone around you can travel in comfort.
