Luggage weight doesn’t count for allowance when it is on your person or in your hand luggage.
When it comes to flying, people often think of the weight of their bags. But actually, when it comes to carrying luggage on you (or in hand luggage), it does not matter how heavy or light you are. Luggage weight doesn’t count for allowance when it’s on you!
If needed, wear or carry your heaviest outer layer (like a jacket) is always wise for often-freezing plane cabins.
