Just wanted to add a quick update since I'm in the lounge right now:

- Even though I'm flying out of the B gates (southwest), TSA told me to just go to the first-class security line in the D-gates and tell them that you are going to the amex lounge and they will check your B-gate boarding pass and send you through security as normal. You do have to exit the D gates and re-enter security at the B gates when done. I suppose pre-check would work here too if you are registered.

- Cent card holder is free and can take two additional guests in, all at no charge.

- Internet is smoking fast - speedtest.com says 90mbit download speed

- They were out of the Centurion gift that they were giving out, which I guess was a small cosmetics-type case? They said they had just run out today and would be having a new gift soon.

- The drinks were made well, fairly top-shelf liquor and after testing two to be sure, strong.
