Adding: "It’s also a choke-risk in turbulence or bumpy landings. Wiggling your lower jaw and doing some big fake yawns sorts your ears out more safely."
Speaking about excessive gas, which can also be caused by chewing gum, Ben said: "Excessive gas is never fun on a plane, especially for the people sitting next to you.
"So why get more bloated and put extra oxygen into your system?"
He added: "Cutting out fizzy water (and saying no to Champagne, if you’re lucky enough to be offered it) makes everyone more comfortable."
