Passengers of United Airlines will experience greater peace as the airline strengthens its enforcement of noise control regulations. The company has revised its Contract of Carriage, which details the Terms and Conditions for ticket holders, to permit the removal and possible banning of passengers who fail to use headphones for their music, films, and social networking.

In line with United’s Refusal of Transport rule, the airline is entitled to deny transportation or remove any passenger for designated reasons. Among these safety measures, which cover inappropriate attire or the possession of weapons, is the new stipulation requiring passengers to utilize headphones while engaging with audio or video material.

“We have always promoted the use of headphones when consumers are enjoying audio content — and our Wi-Fi guidelines already advise customers to wear headphones. It seemed appropriate to clarify this further by incorporating it into the contract of carriage,” commented United spokesman Josh Freed.

Most airlines have regulations encouraging passengers to use headphones during their flights. For instance, Southwest includes headphones as a requirement on its website FAQ, while Frontier features headphone stipulations in its baggage policy. United is the first to explicitly enforce this policy within its passenger contract.

Throughout the industry, there are rising accounts of passenger disturbances during flights, including violent confrontations with other passengers and airline personnel.
