Sure, there are a lot of things like this you can do. It would eat up a minute of your time and cost a premium to buy a tiny packet of an individually-wrapped biscoff. Or you could spend ~$36 to buy a box of 300 biscoffs that occupy a space in your cupboard, and then every time you fly, you take one out of the box and put it in your carry-on, and resist the temptation to eat it unless you are 10km high.
