CLT is way, way, way, way better than LGA/EWR/JFK.
I really like the rental car setup and new access roads: from I-85, you just turn onto Little Rock Road and it's a pretty straight shot right up to the rental car dropoff, which is right in front of the main terminal, and with TSA Pre-Check, you're through security in minutes. Since it takes just minutes from I-85 until you're through security that way, it's like a small-town airport!
