Why your Centurion Lounge has a waitlist now, and the airports where it usually doesn't

If you have walked up to a US Centurion Lounge in the last two years and been told to scan a QR code and wait for a text, you are not unlucky. That is now the normal way in at the busiest locations. The waitlist exists because American Express has sold far more lounge access than it has lounge seats, and the rules it has changed since then trim the edges without touching the core problem.

How the waitlist works

The queue lives in the Amex app. Under your card's benefits you pick the lounge, and if there is space you get a QR code to show at the desk. If there isn't, you join the waitlist and get a text or email when it is your turn. You then have about 10 minutes to show up. Miss that window and you start again from the back. There is no advance reservation and the alert doesn't promise a time, so you can't plan around it. Amex rolled this out across US Centurion Lounges from late 2024, and AwardWallet's guide, updated in April 2026, says you can join from up to three hours before departure, from anywhere in the airport. Being on the list doesn't always mean skipping the physical line either: early reports described people holding a valid code and still queuing behind walk-ups at the front desk.

The important detail for this piece: the digital waitlist is a US feature. International Centurion Lounges, including Hong Kong and Tokyo Haneda, don't use it.

Why the lounges are this full

Three things stacked up.

More cardholders. Amex raised the US Platinum fee to $895 in its September 2025 refresh, and demand went up, not down. On the October 2025 earnings call, CEO Stephen Squeri said new Platinum acquisitions were "running at twice the level before the refresh." Every one of those accounts comes with Centurion access. By the April 2026 call Amex was still describing strong new-customer acquisition, alongside plans for new or bigger lounges in Las Vegas, Boston, Charlotte, Dallas-Fort Worth and New Delhi. More seats are coming, but they are trailing the cards.

Access rules that only nibble. The Centurion access page today allows entry within three hours of departure, or within five hours of a connecting flight. That five-hour connection limit, plus a rule that guests must be on your flight, took effect on 8 July 2026. Before that, connecting passengers could arrive as early as they liked and a guest only needed a boarding pass for any flight. Those changes stop the day-long camper and the friend who tags along, which helps at the margins. They don't cap how many eligible cardholders can turn up at 5pm on a Thursday. Our explainer on the 3-hour rule covers how this compares with other networks.

Guest fees that didn't thin the room much. Free guests ended for US Platinum in February 2023. Guests now cost $50, or $30 for children aged 2 to 17, and come free again once you spend $75,000 on the card in a year. The fee kept some extra bodies out, but the spend waiver means the heaviest users, who are also the most frequent visitors, still bring two people in. The details are in our guest policy guide.

Where you will wait

Las Vegas is the clearest case. Most departures from LAS are leisure travelers, a huge share of them carry Platinum cards, and they all funnel through the D gates. NerdWallet's reviewer joined the waitlist on a Tuesday in early December, about as quiet as Vegas gets, and still waited 20 minutes before a second line at the desk. The 2020 expansion to roughly 13,400 square feet didn't end it. In March 2026 Amex opened Sidecar a short walk away. It has 33 seats and only takes you within 90 minutes of departure. I see it as a smart pressure valve with too few seats to fix anything, and it has no reservation system of its own.

JFK Terminal 4 depends on the clock. A July 2026 review on Exit Row Please found no line in the morning, which the writer said was the first time they had seen that. They warned that the lounge gets crowded after about 2pm and worst between 4pm and 8pm, when T4's evening long-haul bank goes out. If you're on a morning flight, go. If you're on the 7pm to Europe, join the queue from the security line.

LAX Tom Bradley is busy most of the day, and its layout makes it worse. Travel Codex's reviewer called the space always crowded and pointed to the long, narrow floor plan. My advice: don't change terminals to get there.

Where you usually won't

Hong Kong has no app waitlist, but don't read that as empty. It is a 250-seat lounge with four showers and the site rates it 4.7 overall, and it still had a crowd at the door at opening in a 2024 MileLion review. What's different is the mix of people: far fewer local cardholders at any given hour than at a US hub, so the peaks are shorter. If you arrive mid-morning or mid-afternoon you will generally walk in.

Tokyo Haneda is real and on the site: the Centurion Lounge at Haneda opened on 16 July 2025 in Terminal 3 near gate 114. Our record lists 122 seats and hours of 08:00 to 22:00. There's no app queue here either. A Roame reviewer who visited in its first week found it calm compared with US locations, though One Mile at a Time noted a reader who found it packed in the same week. With 122 seats it can fill quickly when a few US-bound departures line up, so I'd call it usually calm, not guaranteed. We have only two ratings on file for it so far (3.5 overall).

What the site's readers say

I wanted to back this up with reader check-ins and comments from Lounge Frog itself. Right now there are none on these six lounge pages. The wait patterns above come from published reviews and Amex's own access rules. If you've waited, or walked straight in, at any of them, leave a check-in or a comment on the lounge page. That's the data that will make the next version of this piece better.
