The Sun reports that the former Suits actress, 36, wrote on her now-closed website The Tig that hand sanitiser is something she packs in her hand luggage for every plane journey, without fail.

She explained: “I’m no germophobe, but when I get on a plane I always use some quick hand wipes or a travel sanitiser spray to wipe it all down: that includes the little TV, the service tray, and all the buttons around your seat.”

The future Royal admitted that her habit can make her look a bit odd to her fellow passengers, but she reckons it’s worth it to avoid getting sick.

“Sure, the person next to you may give you a side eye, but at the end of the flight, you’ll be the one whistling Dixie with nary a sniffle,” Markle said.

She’s got a point, as studies have shown that more than one in five people who travel on planes suffer from a cold or the flu after the flight.

According to research by Skyscanner, the tray table is the dirtiest place on a plane, followed by the overhead air vent, the toilet flush button and the seatbelt buckle.

Markle also recommended taking probiotics while on the go to boost your immune system.

“Always travel with a high strain probiotic, and hydrate like you’re dying of thirst — because even if you’re not, for your body — the thirst is real,” she said.

“This dynamic duo of probiotics and agua will keep your gut health in check and honestly stave off jet lag if you’re globetrotting on your travels.”

Prince Harry and Meghan Markle are inviting 2600 people to their wedding, with 1200 being members of the public.

They will have access to the grounds of Windsor Castle on the big day in May.
