How do i reserve a ADA parking spot?

You can go directly and it will be cheaper

If there is no space in the main parking lot, there is also an airport parking lot next door. He parks you there and a little truck brings you to the airport

You have to do it on the CBX page and do it at least a few days before your trip

There is availability all the time so just show up and you will be taken care of without a hitch
