The smartest move is to store your trimmer in your checked luggage rather than your carry-on, despite the temptation to have it handy. This not only maximises space and allays security worries, but it also gives you peace of mind and keeps you safe from any in-flight accidents. Therefore, do yourself a favour and allow your trimmer to travel in style—in your checked luggage—the next time you go on a trip. More: trimmer should be in check in luggage
