Whether it's clipping toenails or completing a ten-step skincare routine, a plane is not the place to do your "body maintenance".

That's the warning from Irish Independent journalist Kirsty Blake Knox, who was speaking to Lunchtime Live about her dos and don'ts when travelling internationally.

"There are horror stories of people clipping their toenails and bleaching their eyebrows on flights," she said.

"You just have got to be conscious of people's personal space ... I don't think anyone should be that laid back and comfortable on a flight."

Ms Blake Knox said passengers should be more aware of the people around them.

"Think about the passenger next to you or what their response would be if they turned around to see someone wearing a sheet facemask – which I kind of think almost looks like a Freddy Krueger," she said.

"Any sort of body maintenance is a no."

One listener, Kathy, said she "hadn't been scared off by the facemask scenario yet" but took issue with parents who allow their children to listen to devices out loud.

"You're listening to Mickey Mouse for three hours across the water at full blast on the loudspeaker," she said.

In some situations, some children may have to go without headphones, according to Ms Blake Knox.

"Our one-year-old, she just won't wear them, she hates them," she said. "It's the lesser of two evils – which would you rather hear, Mickey Mouse or a baby crying for 45 minutes or an hour?"

Kathy said the issue lies with the volume of the devices.

"It's full throttle – you're thinking these kids are going to be deaf by the time they're eight," she said.

The ideal state for parents is for their children to be "quietly content" but this is not always possible, according to Ms Blake Knox.

"Anytime I've been on a flight and my kids start getting upset, I'm not laid back about that," she said. "I'm the most stressed person there."

"The parents are the people who are going to be most worried about that, who feel the most societal pressure to get them to calm down."

One listener, Caroline said she finds people have little awareness about personal space when travelling.

"A lady in front of me draped her long hair over my headrest – I was just amazed by the lack of awareness," she said.

"She was encroaching on my personal space, and she didn't seem to be one bit bothered about it.

"There is a general lack of awareness with people travelling, they just don't realise what they're doing or the consequences of those kinds of actions on people in such a tiny little space like a plane."
