Booked one a few weeks ago for my family connecting in ATL. It was sort of funny as they had no idea (still don't) but I was watching when we hit the ground and I saw the Porsche outside of our original gate, all of a sudden they switched the gate from A to F, I watched the car shoot from A terminal to F, then they decided to go back to the original gate at A so watched her chase the plane back to the original gate. By the time she met us on the jetway, we had a pretty good laugh about it. Drove us to F SkyClub, escorted us from the tarmac up an elevator to the main terminal level right up to the SC. There were no Reserved sections available, which she apologized for, but sat us upstairs. They came back to get us a couple hours later and brought us to our next gate, walked us up the jet bridge steps from outside, and proceeded to just have us board the plane. They had our boarding passed and the VIP Staff walked up the jetway and scanned our BPs for us.
Speaking to her on the way to the SC, she said that ATL has 8-Pcars. She was a previous CSR, there is another guy there who was a previous DL Mechanic who took us just outside of a A350-900 and gave us lesson on the plane and info on the engines that are used on it. Very cool experience.
