At the Nashville international airport they have accessible parking for handicap autos with either hangers or permanent handicap tags. All you do is send in the paperwork and they send you the sticker and membership card in the mail.
When we come to St Maarten for 3 weeks it is over $700.00 and we never have to pay a penny.
Free to all that join the program.
Also the handicap parking is always close to the main terminal.
You should check to see if your airport offers this if you have a handicap hanger.
