DON'T be tempted to whack on a pair of flip flops when settling into a long flight, according to experts.
An ex-flight attendant has warned that while this may be comfier, it is also much more dangerous.
Tony Kuna, who used to work as as a member of the cabin crew, explained that it could cause problems if there is an emergency during a flight.
He wrote on Quora: “During an emergency, all sorts of debris and unpleasant ground surfaces will block your way towards the exit, as well as outside the aircraft."
“If your feet [aren’t] properly covered, you'll have a hard time making your way to safety."

Tony added: "Imagine destroying your bare feet as your run down the aisle covered with broken glass, fires and metal shards.

CNN aviation analyst Mary Schiavo's main recommendation when travelling is also to always avoid wearing flip flops.
She said: "Please wear sensible shoes and leave them on until after take-off.
"I see people boarding with flip flops and I think if you have to get up and run and you fall down or you can't run, you're not only going to hurt yourself, you're going to hurt dozens of other people on this plane.
"So get some shoes."
And aviation expert Christine Negroni previously told Sun Online Travel: "The riskiest time on a flight is during landing and I think it should be a rule to have shoes on during this time.
