As I've mentioned before, I work at an airport. I'm in communications, which means I monitor security cameras, alarms, dispatch police, medical, and fire, as well as customer service and other things.
Before I get into my post, I just wanted to mention to those with autistic children, who plan to travel, check with your airport. We have a program at ours for autistic children and their parents who are planning to travel. The family comes to the airport and is given a tour and things are explained. They practice going through security, and actually going onto a plane and sit in a seat and then the plane is explained. It has been very successful. (Kudo's to Southwest as they are the airline that works with the program).
Our airport is small. We service about 3 million a year, so you can imagine larger airports. If you have a disability that isn't obvious, you need to inform people, and people will help.
I've had to dispatch police many times to take care of someone who is headed to rehab, alone, and decides to tie one on before heading there, and then flips out. How is the person checking them in supposed to know that? The police here only restrain if the person is violent. In most cases, they work hard to contact someone to come pick them up, and stay with them until someone does.
The ones that get me angry, are the people who put their elderly parents on planes who have Alzheimer's, alone! Then panic when the person doesn't get to their destination. They blame the airline for losing them. Did they inform the airline when they checked them in? No. But, I'm the one who gets the call. Airlines cannot give out information on passengers, due to privacy laws. Even if you say you are the daughter, on the phone, what proof do you have. So I have to call the LEO to talk to the airlines to try and locate these passengers, while being yelled at by the adult children.
I could go on, but wont'. I see this guy as a SS and do not find fault with the airlines at all for his issues.
