We flew, as a family, for the first time in 2.5 years. Darus traveled a lot when he was younger, but ever since he's been mobile, it's been quite challenging to contain him on a plane. Also, most people just do not understand Darus' inabilities to attend and/or pay attention. We're constantly given looks and stares of, "why can you not control your child?", which can be quite discouraging.
Darus has made a lot of progress though this past year and we were willing to try again, and I'm glad we did! We had a really wonderful time visiting my family and friends in Wisconsin and Michigan.
I'm also very thankful to Love that Max for her helpful post regarding airline hotlines to specifically help/cater to people with disabilities. Thank you @Delta for making our trip as smooth as possible!
