When it comes to flying, the experience can be an absolute nightmare for some people.
The idea of being trapped up in the air is terrifying and every little bump and rattle you feel during a plane journey could prove unnerving.
If you are someone who's afraid of flying then there's one thing you certainly shouldn't be doing while on a plane - according to a pilot.
And that's focusing on the facial expressions of flight attendants and trying to interpret what they might be thinking or whether something is wrong.

Writing in his book, Cockpit Confidential, pilot Patrick Smith reveals that trying to read a flight attendant's expression is pointless.
This, he claims, is because it's so easy to misinterpret the situation.
He wrote: "That glazed look in the flight attendant's eyes is probably one of exhaustion, not fear.
"Nervous flyers are prone to envision some silently impending disaster, with distressed crew members pacing the aisles and whispering to each other in secret."

He continued: "In reality, passengers will be told about any emergency or serious malfunction."
The expert also made the reader aware that members of the crew will not alert passengers of minor malfunctions if they pose no threat to safety as it could cause people to panic.
"Being blunt about every little problem invites unnecessary worry, not to mention embellishment," added Mr Smith.

As well as this top tip, a frequent flyer also recently shared their advice for booking seats on a plane.
Writing for escape.com.au , John Burfitt revealed he always opts to purchase the 'worst' seat on a plane when he travels.
Where is this seat you ask? The window seat at the very back, located right near the toilets.
He realised at the back of the plane no one would be behind him so he wouldn't spend the flight being kicked in the back.
Other benefits of selecting this seat include never getting hit by the trolley, not being bumped by passengers as they pass in the aisle and being able to lean into the corner wall to doze off.
