Which lounge you can use depends on your flight more than your card. The same Amex Platinum opens 11 of Atlanta’s 13 lounges on a Delta flight and 2 of O’Hare’s 14 on a United one. Priority Pass, the name most people know, opens nothing at Denver or Newark.
So ask three questions in order: which airline is operating this flight, what fare or cabin am I in, and what’s in my terminal past security. The card comes fourth.
Lounge finders list what exists. For the numbers here I read the airport, airline and lounge pages for 161 airports, up to November 6, 2026, and restated the rules by flight. Of those 161, 82 have no lounge at all. The other 79 have 422 between them.
Priority Pass opens 123 of those 422
At the big US hubs, the count is short, and where they sit matters more than how many there are.
| Airport | Lounges | Priority Pass | Where they are |
|---|---|---|---|
| Denver | 8 | 0 | |
| Newark | 6 | 0 | |
| Los Angeles | 17 | 1 | Tom Bradley International |
| Atlanta | 13 | 2 | Both in Concourse F |
| O’Hare | 14 | 2 | Both in Terminal 5 |
| Dallas-Fort Worth | 20 | 2 | Terminals D and E |
| JFK | 19 | 8 | Terminals 1 and 4 |
Atlanta’s two are a train ride away from most domestic gates, which is fine on a long layover and silly on a short one. O’Hare’s two are in Terminal 5, and United and American leave from Terminals 1, 2 and 3, so expect to go through security again. JFK has the longest list, and none of it is in Terminal 5, where JetBlue flies. A JetBlue passenger holding Priority Pass at JFK has eight lounges and no way to reach them without leaving security.
Some memberships cap your visits, and space isn’t guaranteed at any of them.
Amex Platinum, flight by flight
The Platinum card is the best example of a card that changes with your ticket.
| Your flight | What opens | Count |
|---|---|---|
| Delta, Atlanta, not Basic | Sky Clubs, Centurion, Priority Pass | 11 of 13 |
| American, Dallas-Fort Worth | Centurion in D, The Club in D, Plaza Premium in E | 3 of 20 |
| United, Denver | The Centurion Lounge only | 1 of 8 |
| United, O’Hare | Two in Terminal 5 | 2 of 14 |
On Delta, three conditions sit on top. The flight must be operated by Delta and can’t be Basic Economy. You get 10 visits per Medallion Year unless you spend $75,000 on the card in a calendar year. And you can enter only within 3 hours of departure, or during a layover. A flight booked on Delta but flown by a partner may not count.
Centurion has a 3-hour limit too. Priority Pass through the card needs enrolling first, so sort that out at home and not at the door.
Status has more traps than cards
Airline status looks simple and isn’t. These are the ones that catch people.
| Status | The catch |
|---|---|
| United Premier Gold | United Clubs in the US need an international Star Alliance flight. A domestic United flight doesn’t count |
| AAdvantage or Atmos oneworld Sapphire or Emerald | Lounge access through status needs an international flight, and North America and the Caribbean don’t count |
| Delta Gold, Platinum, Diamond Medallion | Sky Clubs need Delta One, Premium Select internationally, or Delta First to Mexico, Canada or Central America. Partner lounges work in any cabin |
First class is a trap of its own. Domestic first on American, Delta, United and Alaska doesn’t get you into most lounges. International business does, on many airlines, though American’s rule leaves out Canada, the Caribbean and most of Mexico.
How I’d decide
If you fly one airline from one hub, a club membership or that airline’s card gets you more than a general lounge card.
If you fly a mix of airlines through big hubs, check the table above for your home airport before paying for anything. A card with a long lounge list and none in your terminal is a card you’ll stop thinking about.
If your connection is under an hour, don’t plan on a lounge at all. The train and the line at the desk will eat it, and you’ll be working out when boarding really starts over a biscuit. On a long delay it’s a different story: stay near the gate until the new time holds, then go.
These rules change often
These are facts restated from public pages on the date above, and rules change often. Hours are as listed by each source. Some American and United pages were harder to confirm than others, so check the door rule on your airline’s site before you count on it. United Polaris lounges aren’t covered, because the rule depends on a ticket detail I couldn’t source. Other airports are at the lounge access page, and the rest of the morning is in when to leave for the airport.
Tell Skycap what you carry and it lists the lounges past security that you can use on this flight, with what gets you in. A lounge it couldn’t confirm says so. How it works at the airport
