Airports that house a Boots include Heathrow Airport, Gatwick Airport, London City Airport, London Stansted Airport, London Luton Airport, Manchester Airport, Birmingham Airport and Leeds Bradford Airport.

Her hack is to avoid taking toiletries altogether and to plan ahead, provided you’re staying in a hotel.

“If you’re staying at a hotel, take a look at its website to see if there are any mentions of the toiletries provided in the bathroom.
“If not, send an email and ask, then you don’t need to take those products with you.”
