I lost my mother 15 years ago at the age of 92. I have a video of her last plane ride when she was 91.5 years old. She had a blast. She was hard of hearing but with the head set on she could hear better during flight than anytime on the ground. Over the years she rode with me several times and always enjoyed it.
Take your mom for a plane ride in smooth air. She most likely will enjoy it, mine always did.

I wish I could do it again.
Here's to MOMS everywhere.
