A video of two women playing loud music on a TUI Airways flight has gone viral, sparking debate on social media about plane etiquette. The women were seen singing out loud and playing music, while other passengers covered their ears. The video has received 15.5 million views on Twitter and many social media users agreed that the women were being inconsiderate to other passengers. The incident has also sparked discussion about expanding laws that govern behavior on flights. Last year, Delta Air Lines called for the expansion of the “no-fly list” to include people who have been convicted of federal charges related to onboard disruption, and to encourage other airlines to share their no-fly lists. So far, there haven’t been any new updates on Delta’s proposal.
