The 19 year old had never travelled on a plane before finding fame with the group, and his pals in the group took the opportunity to play a prank on him during their first journey together.
Malik recalls, "I'd never been on a plane before, which is a bit sad and depressing - I'd never actually been anywhere outside of the U.K. before. So I was a bit nervous about it.
"The lads made me feel really (uncomfortable) because the first time we got up into the air Louis turned to me and goes: 'This is where the plane does a loop the loop, goes upside down'. I believed it, I was so gullible, the first time."
