Since in your previous posts, you brought up US Airports as examples, it really has more to do with the nature of lounges at US Airports as to why each of those airports has limited to no PP lounges.

Most airport lounges in the US are operated by one of the US3 carriers (AA/DL/UA). Each of these airlines sells "memberships" that allow access only when flying that carrier or a partner. Each also has a credit card that provides roughly the same access. In the US, most PP holders have it because they have a different premium credit card that offers it as a perk. Accepting PP would mean they are competing against themselves. Why buy a membership to a lounge when you can get in via PP at a reduced price without access restrictions?

Some airports have non-US carrier lounges that at times accepted PP, usually limited hours when their own flights weren't operating or on a limited capacity basis. While some still take it, others either to your point didn't find the marginal revenue worth the marginal expense of operating the lounge extra hours or didn't find the extra revenue worth the abrasion of people showing up at non-PP hours and arguing to get in, or showing up at other locations and saying they should get in.

Lastly, some airports (particularly mid-size airports) have independent lounges (e.g. The Club/Aspire/Plaza Premium) that take PP, but many airports do not. LAX/EWR/DEN/DTW/DCA/PDX/PHX each don't have any to name a few, others like ORD only have one that is away from most travelers. Secondary airports sometimes encourage these independent lounges because they want premium customers or international airlines to operate but can't attract an airline lounge. Many airports in the US don't have any lounges whatsoever.

As far as a solution, at least in the US, there isn't one except lower expectations. PP is nice to have, but, in the US is not a good primary lounge card unless you happen to always fly at airports with PP lounges.

I appreciate your ground-level insight into lounge dynamics. But because PP is, as another poster here said, a way for (mostly independent) lounges to monetize unused capacity in off-peak periods, PP subscribers are like non-rev / standby airline passengers. When a lounge is full they're the lowest-priority candidates to get in. Rejection is such a common element of the PP experience, I think it's impossible to charge more without changing that. And I don't know how PP can possibly do that, as (A) it has no control over lounge access decisions, and (B) PP will happily sell an infinite number of memberships to a finite quantity of lounge floorspace.

Add the sad fact that lounges either disappear off the "available" list without warning, or are de facto unavailable to PP members despite PP's assurances to the contrary (looking at you, T5 ORD), and membership looks like a poor deal at $99 plus per-visit fees ... never mind some lofty multiple of that. If I'm going to pay $500 or $600 a year for lounge access, I'm going to need to see something definite in return, not a glorified lottery ticket.

The essential problem with PP isn't lounge crowding (although that's a problem everywhere). It's their inability to control administration of PP benefits. As Tom Waits said, the large print giveth, and the small print taketh away.

From an airports perspective, they have limited space for lounges as well.

Maybe the removal of the PP benefit from the Amex Hilton Aspire and Surpass cards is evidence of higher costs for the issuer. They did not discuss the why in my statements.
It's also possible that lounge overcrowding and denied entrance has reduced the perceived value to those customers. I moved from the Aspire to the Platinum card since I have been able to access lounges through that card and added a bunch more.

My guess is that Priority Pass wasn't worth it for the Aspire. Amex probably pays a flat fee per user to activate the card and many users were likely either not using it as they didn't fly that often and/or had another premium card with it like the Amex Plat/CSR/etc.

Clearly Hilton came to the conclusion that PP was not worth it for them. My guess would be that they wanted to keep all of the cash flows for themselves regardless of whether they thought the holders of the card might find PP useful. As a business decision I cannot disagree with it. As a holder of the Aspire card the fee raise coupled with the dropping of the PP perk caused me to switch to the Platinum card.

No trouble today at PVR despite the spring break crowds. It helps that the airport has two large VIP lounges that are both on PP program. So not completely useless outside USA.

Do anyone know the current status about the H&J lounge in MIA?

I've read access can be denied in the afternoon, do anyone know if we would be in the clear if we show up at 12pm?

Priority pass is useless
 

They are gone. Earlier they always provided a lounge with great food or reimbursement. Now it’s a scam. No food in the entire LAX airport!

Will be downgrading my CSR after july for this reason

Club at JAX was easy to get into yesterday as it was roughly half full at 1:30pm. Most seats have been refreshed and while it is still just soup and salad (and brownies) they have nicely upgraded the food offerings compared to when we were there last fall.

I haven't been to this club since I got my DL reserve card last fall. I was thinking of going this weekend and was wondering If they had made some changes . The last few times I visited this lounge it was depressing. Glad to hear that it is looking a bit better.

It is still a modest lounge. Some seating still needs refreshing. We found the people to be nice and the food has definitely moved up from barely there to reasonable. I have not been in the Delta lounge across the concourse, but I think these were necessary steps to be acceptable relative to that.

I am at the little JAX lounge now and you are right they have definitely done some improvements but the last seating row does need a little TLC. I've been coming to this lounge since it opened and it has gone through ups and down but glad to see it is slowly going back to how it used to be. The SC is OK, a little better than this one and Food offerings slightly better. I wouldn't definitely compare it to the ones in bigger airports but it is small and cozy. I still prefer being at the lounges over being at the gate.
