1. They admitted fault for not delivering the scooter in the timely manner and in a condition other than the one they received it in (both a violation of federal law)
2. Possibly, but it was BCN and JFK. BCN is known for being good with mobility assistance and JFK is it's charming self but it's also my home airport and I've never had broken equipment on return there despite many flights. I've had other issues with AA and mobility equipment before, in hindsight should have resisted the irresistible fare I booked.
3. I don't have home insurance. Don't own my home. The issue is not cost of getting it fixed as it was a travel rental (I don't bring my full-time scooter to Europe because of size) and I was lucky that the rental company's mechanic was able to take care of it next day so I didn't get charged for that, it was my complete inability to get home without someone to assist me as I had zero mobility without a functioning power operated device. No one in my home means I had to hire someone to be there for me... Otherwise I'd still be sitting in a cab!
