An EVA Air business-class passenger left others shocked when he resorted to using a drinking glass to scratch his scalp during a flight. The incident happened on a flight from Taiwan on September 24, and captured the attention of fellow travellers.

The passenger, seated on a Boeing 787 Dreamliner, chose to use the rim of a glass for relief from an itchy scalp. The peculiar grooming technique was recorded by a horrified passenger sitting behind him, as reported by Viral Press.

The witness found the sight unsettling, expressing that the premium cabin experience took an unexpected turn. ‘This is disgusting. It’s a cup, not a massage comb,’ remarked the astonished observer.

The passenger videoing the event lost his appetite for the upcoming meal, commenting, ‘No one wants to eat your dandruff. I’m really going to vomit,’ according to Viral Press.

The EVA Air flight landed safely, reported by NewsFlare.

EVA Air, founded in 1989 and based in Taiwan, seems to be gaining attention for unfortunate passenger conduct. Texas etiquette expert Diane Gottsman spoke to Fox News Digital about the inappropriateness of using objects for personal grooming in public. ‘Using a glass to scratch [one’s] head is completely inappropriate,’ she stated.

She elaborated, ‘Any time you see someone scratching themselves with an object, or even with their fingers in public, it’s unappealing and somewhat alarming.’

Public behavior on planes has been a growing concern among travelers. In March 2026, another passenger faced criticism for resting feet on a window, sparking a Reddit discussion.

One user, experiencing discomfort, commented, ‘First time experiencing the feet in my face in five years. Travel monthly. In first class, and this lady put her feet on my arm rest. I shoved them off. And five minutes later, she has them up on her window. At least she has socks on. But come on, people! It’s a 4.5 hour flight.’

Gottsman emphasized the importance of respecting public settings. ‘When you’re in your home, you are in a private space. [But] when you are out in public, there are different standards because you are around other people and must be aware of your surroundings and the comfort level of others.’
