Why do your nails before a flight when you can kill time on the plane and do them whilst you're on the way to your destination?
That's what one TikToker did, but her actions have caused quite the stir online.
The woman, named Sarah, took to her TikTok page to share a video of her giving herself a glam manicure on the plane, and she captioned it: "Had lots of time to kill."
"Paint my nails with me on a plane," she wrote over the video.
Sarah, who posts under the username @heluviee, could be seen using a nail tool to paint on a pink and green swirly pattern, and her UV nail lamp was plugged in and ready to cure her nail art.
By the time the plane landed in Barcelona, she had a perfect manicure - all ready for her holiday!

In the comments section, everyone was asking the same questions - whether the nail varnish smell was bothering other passengers, and how she was allowed to take the polish on the aircraft.
Some joked it seemed "illegal" to be able to do that on a plane.
"That's such a good use of that dead time! Does the smell not bother other passengers at all? That would be my only fear," one person wrote.
Sarah replied: "Gel doesn’t have that polish smell like regular polish! I was asking my fiance every 30 seconds if he could smell anything."
"Why does this feel illegal but I know it’s not", another added.
Sarah answered: "LMAOOO I felt like I was doing something illegal, had to fight the urge to hide everything whenever someone walked past."
She added: "Just to clarify for repeat comments- TSA let me through with this in my carry-on.
"Gel polishes made recently are non-flammable and don’t have a smell/fumes like regular polishes, and not a single flight attendant who walked past me commented.
"Regular polish definitely should NOT be used on planes, but gel does not carry the same hazards."
However, several people claiming to work as flight attendants warned that this would be a big "no-no" on a plane.
Someone replied: "From a flight crew advised. This is definitely not allowed.
"It’s flammable and it puts in danger your life as well as the other passengers.
"It’s not only about the nail polish but the machine you are using.
"You are aware we use oxygen inflight. Is not convenient to have things that could cause sparks or fire in any type, shape or form.
"It’s not safe for you and those around you."
While another flight attendant added: "Lol I’m a flight attendant this is a huge no-no - you’re not allowed to do this on a plane."
