Assuming you would like tips for entertaining a 7 year old on a plane:
1. Bring along their favorite book or toy to keep them occupied during takeoff and landing.
2. Download some fun apps onto your phone or tablet that they can play during the flight.
3. Pack some healthy snacks and drinks to keep them fueled throughout the trip.
4. Bring along a travel pillow and blanket so they can get comfortable and take a nap if needed.
5) If you're traveling with another adult, take turns watching over the child so each of you can have a break at different points during the flight.
