what is cost of parking?

Depends on when you get there and which parking lot

I just paid $35 for what I assume was considered five days in Long-Term Parking Lot 2. I arrived Tuesday morning about 7:30 am and left on Saturday about 4:00 pm. That, of course, would be $7 per day.

Google clt parking. There are low cost lots that will take you to the terminal.

It depends on what time you get there my mom paid for free parking and you have to ask someone what is the actual cost of parking

There are many options, look on the website in the parking section.
