American doesn't seem to give us the secret Concierge level but United does for theirs, cant remember what it is called.

I would still sign up for all of them for the times you just can't make it happen. We also tend to have a bunch of scheduled flights on Southwest. Good thing with Southwest is the company buys business select so you gain miles pretty fast.

Very few hotels give points, some give stay credit. Get them all for the few times you can get points. Hotels will usually give you the benefits of your status but not always. I use my Marriott credit card for all my spending and thus usually have high tier status. Sometimes you get a free breakfast you otherwise would not get.
