, you should also consider Priority pass, I believe there are some $300 promos out there and you will get many more lounges.
I have Priority Pass and use it. There are three membership levels. Most of the time, you can find special enrollment offers. However, Priority Pass does not have lounges at SLC or CVG. Additionally, unless there are airside connectors, reaching a Priority Pass Lounge on another concourse or in another terminal is near impossible these days.
