When travelling with children, a well-packed carry-on can be a lifesaver for keeping them entertained during the flight. Start with a selection of their favourite books or colouring books, paired with some crayons or thin felt tips to minimise mess. Small puzzles or travel-sized games can also provide hours of distraction; look for magnetic versions that are easy to manage in the confines of an airplane seat.

Consider including a tablet loaded with family-friendly films, educational apps, and audiobooks, but don't forget to bring headphones so they won't disturb fellow passengers. A few small toys—perhaps a beloved action figure or stuffed animal—can offer comfort as well as entertainment.

Snacks are crucial too; pack a variety of their favourite nibbles to keep hunger at bay. A surprise treat can be a delightful distraction during the flight. Finally, remember to bring a little bit of their routine, whether it's a small blanket for comfort or a familiar sleep mask to encourage rest. With these essentials in their carry-on, you’ll be well-equipped to make the journey a pleasant experience for both you and your child.
