This is a bit off topic but it is really sad for our wheelchair friends: many otherwise potty trained people have to wear diapers or, more likely, catheterize themselves when they fly, because the on board bathrooms are too small. I find this inexcusable. My own father has to sit in his dirty diaper when he flies because he needs an aide to change him and there is no room for two in these bathrooms. Forget the Mile High Club — this is an atrocity that people like our beloved JimRob here cannot fly comfortably.
In my mind I already solved the problem. Have the furthest rear restrooms face each other in the galley (like many do) and have some fold away doors that can, for a disabled passenger, seal the two bathrooms into one larger room, so that people can use them with an aide, or be able to be helped to the toilet if lower body disability. You would have two normal small bathrooms all the time until someone disabled needed a turn.
Unfortunately there are limits to accommodating people who have body issues that prevent them a comfortable ride....sometimes it's the size of the people who might otherwise be able to help that takes up the room where people might otherwise have the assistance needed. That' goes for those assisting as well.
When planes start making accommodations for some people then the others demand likewise for their particular needs...it becomes a circus and nobody is happy. People already complain about the size of the pillows for crying out loud!
State wise there are 'options' for travel other than flying. Vans can be suited well for the handi-capped as well as trains etc. It might mean more planning and longer but workable.
Yes, sad. My wife's elderly mother wears adult diapers, especially when we take her from the assisted living facility for trips. Once in a while, there is a distinct odor when I assist her into our vehicle, as she cannot get in on her own, and I realize she soiled herself. I didn't think about what the situation is when flying; hope airlines make it more bearable in the future.
