Andrea Wallace, 46, found the perfect way to bring as many liquids as she wanted on to the plane without being limited by weight or restricted to 100ml or less.
The mum-of-one shared how she ordered toiletries to click-and-collect from Boots - picking up her items AFTER check-in and security.
Andrea tried out the hack - recommended to her by a friend - before she headed off on her summer holiday to Antigua, the Caribbean, this year.
She stocked up on nappies for her five-month-old son, bottles of shampoo, conditioner, mouthwash, deodorant, suncream and aftersun.
Andrea, a fitness instructor, from Croydon, south London, said: "I heard the hack and thought it was a good idea - I would be saving on space as well as weight."
