With the right items at your fingertips, you can breeze through security, stay comfortable on the plane, and have your essentials ready upon landing. This guide covers everything you need to know about what to pack in your carry-on bag, from travel documents to comfort items, while adhering to airline regulations like British Airways carry-on bag rules.

Packing a carry-on effectively isn’t just about what you bring; it’s also about how you pack it. Here are some of the best carry-on packing tips to maximise space and keep your bag organised.
