My three-year-old son, Jack, was as excited as he could be to visit his grandma and grandpa in Florida, especially since it meant taking his first trip on an airplane.

We'd just boarded and got buckled in when Jack looked around the plane and frowned. "What is it?" I asked, wondering if he was nervous.

He then asked me, a bit worried, "Are ALL these people going to Grandma's house too?"
