Navigating DFW Airport from North Entrance to Terminal E Parking to Departure

Good evening, I've never flown and don't ever plan on it honestly. I'm just mainly curious honestly. So you got printed out a ticket at that machine and like I don't believe I ever saw you do anything else with it nor did it seem you had to pay? I'm just confused on how a person pays for their parking? All of the paid for parking areas I've ever been in which have been like 2 or 3 you paid at a booth when you first enter the paid parking area and either a machine or person took the payment either cash or card depending on what you want to pay with.

How much is parking per day?

Where did you go to

Do you know where the rideshare area is at ? I’ll be landing at DFW in a couple weeks and plan on taking an Uber

Horrible terminal to drive to and from. The toll road is awful. Upon approach drivers are rude and wont let you in to change lanes. If someone gets to the booth in the wrong toll lane there is no one who can help
Today there were 6 cars.backed up behind a driver. No one would back up nor was there an employee to help
DFW airport driving is a nightmare.

I will be leaving my car in the long term terminal parking! I bought my parking tickets, but I am just confused on how to get there after they scan my QR CODE. Please help. Did you also park your car in the long terminal parking?
