I find the facilities (space, recent renovation) of the AC often to be superior to similar OW J lounges elsewhere. If I'm looking for quiet space with decent coffee, non-flaky wifi and consistently available showers, then the AC does well.

While other OW competition do offer free food, it's often limited. You have to pay for most food at the AC, but at least it's available. I've been to a number of JL lounges where the food selection was truly awful, and the only alternative is to head back to the terminal.

And the AAngels are a cut above anything I've seen in any other OW J lounge. Agents in other lounges are rarely proactive, and often seem put-upon if I ask anything about my reservation that is more complicated than a seat change.
