Over 15 wheelchairs being used. One person in a chair and a party of 5 accompanying for early boarding.
The easy solution to that is to not allow more than one person to accompany the person in the wheelchair. My DIL needs wheelchair assistance d/t peripheral neuropathy. She can walk short distances, but anything further than that is difficult and painful for her. When we flew with my son and DIL from CLT to SXM last November, they only allowed her husband to accompany her through the boarding process. We met them at the gates on both ends, which was fine with us.
Also, my DIL would have been one you’d see walking up and down the plane aisle during flight. It helps her if she moves a little, rather than not at all, which causes her severe cramping. You might not know that to look at her. So don’t judge people you see walking; it doesn’t mean they don’t need wheelchair assistance in certain circumstances.
