One way to help your child feel more at ease during their first flight is by making friends with other parents who are travelling with kids. When you board the plane, take the opportunity to strike up a conversation with nearby parents. Your child can then interact with their newfound friends, which can help combat any fear of flying they may have.
Having a buddy around their age can distract your child from their phobia and make the experience more enjoyable. They can share their excitement, talk about their destination, or play games together during the flight. The presence of another child going through the same experience can be reassuring and comforting
