Some airlines give passengers a simple vanity bag with a basic toothbrush, toothpaste, socks, ear plugs, eye mask, foldable brush/comb, lip balm etc.
If you’re a frequent flier or do lots of business trips and don’t use them, why not offer them to a refuge centre or homeless shelter. People often arrive with none of their personal belongings, so these make an ideal starter kit. These basic items can make a huge difference to how they feel when they are already in crisis.
Here are some ideas of who to ask if they’d like them: Crisis
Shelter
Centre Point
Salvation Army
Refuge
