Here's the senerio. I have a conference in Orlando and I'm bringing my 82 yr DM, and adult DD to the conference hotel a few days before we all transfer to OKW. They will fly alone, and will need support. Mom will need a wheelchair, and my DD has intelectual disabilities. How and when do I order a wheelchair for my mother, and will she and my DD be seated together on the plane, then "retrieved from the first leg to get them to the next gate? There will be no problems on the return trip, as I'll be with them. I've never had to do this, and mom has never had to use a wheelchair to get to the plane before. Thanks for all the help!
