It’s said that you don’t know a man until you walk a mile in his shoes. And you also don’t know what it’s like for older people to travel until you accompany one on a trip.

After flying with my elderly father from Washington, D.C. to L.A. in July, I began to realize that a companion has important tasks that can make a journey easier for older people. I booked non-stop tickets on JetBlue to avoid tiring, confusing connections, and we flew directly into small, manageable Long Beach Airport. Even though my father could walk, I arranged with the airline for wheelchair assistance, which meant we got on board first.

When I took him back to the airport for his return flight to Washington, I got permission from JetBlue to wait with him at the gate instead of saying goodbye at the security checkpoint. I wished he’d had a first-class seat and access to a comfortable airline club. Better yet, I wish I had flown with him both ways. As I watched the attendant wheel him to the lift that took him from the tarmac（飞机跑道）to the plane, I felt like an anxious mom sending her child to school for the first time.

Things can go awry on a plane trip. And then there is the horrifying story about Joe and Margie. When they landed at Dallas-Fort Worth International Airport, a wheelchair attendant met them to help with a connection. But somehow Margie, who had Alzheimer’s disease, disappeared.

I didn’t need to worry about my father wandering away. At 82, his mind was sharper than mine. But his hearing was poor, so I worried about what would happen if he missed an important announcement. Fortunately, everything went just fine. Careful planning made the trip successful.

Next time I travel with a senior, I’ll know better. I hope there will be a next time.
