The Amex Centurion Lounge Network: A Guide for UK Cardholders

Most airport lounge access works on a simple principle: hold the right airline status or fly in the right cabin, and the door opens. American Express Centurion Lounges work differently. They are owned and operated by a credit card company, not an airline — and that distinction shapes everything about them, from who gets in to how the food is funded. For UK holders of the American Express Platinum Card, they represent one of the most tangible benefits the card delivers. Understanding how the network actually works — and where the gotchas are — is worth doing before you turn up at the entrance expecting to walk straight through.

The network launched in Las Vegas in 2013, built partly out of necessity: American Express had spent years bundling lounge access via contracts with major US airlines, and those arrangements began to unravel. Rather than keep negotiating with carriers, Amex decided to build its own rooms. The result is now a global operation with around 30 locations, a serious culinary programme in the US, and an expansion pipeline that includes Amsterdam, Newark and Boston. For European cardholders, this matters most at Heathrow Terminal 3 — currently the only UK location — though that is beginning to change.

What Cards Get You In

Despite the name, you do not need an American Express Centurion (Black) card to enter. The Centurion branding is applied to the lounge network as a whole; in practice, access is granted to holders of the following UK-issued cards:

To get in, you need three things: your Platinum card, a same-day boarding pass for any departing flight, and a government-issued ID. You do not need to be flying with any particular airline, and there is no requirement to be flying in business or first class. Access is limited to within three hours of your scheduled departure, unless you are connecting — in which case the three-hour window does not apply.

Where Are They?

The network spans around 30 locations, with the majority in the United States. For UK readers, the practically relevant locations are:

Stockholm operates what Amex describes as an ‘American Express Lounge by Pontus’ — a restaurant concept rather than a conventional lounge. Meals are complimentary for cardholders, making it genuinely good value, but it is a different experience from a full Centurion Lounge.

What to Expect Inside

Centurion Lounges are consistently among the best-equipped in their airports, particularly in the US where the competition from airline lounges tends to be weaker. The standard offer across the network includes complimentary food and drink (including full bar service and cocktails), showers, Wi-Fi, and a mix of work-focused and relaxation seating. Newer US locations have pushed further: the JFK lounge includes an Equinox Body Lab offering complimentary treatments, and the culinary programme across the US network was overhauled in 2025 in partnership with a group of high-profile chefs, with seasonal menus varying by location.

The Heathrow T3 lounge is the one most relevant to UK cardholders. It sits in a terminal with an unusually strong lounge line-up — Cathay Pacific operates two lounges there, Virgin Atlantic’s Clubhouse is consistently considered one of the best business class lounges in Europe, and Qantas has both First and Business offerings. The Centurion Lounge competes in demanding company, which means the standard it has to meet to feel worthwhile is higher than at most airports.

The Overcrowding Problem — and How Amex Is Responding

Centurion Lounges in the US became victims of their own success. As the Platinum card grew in popularity and its fee became more broadly acceptable, cardholder numbers increased sharply — and the lounges, designed for a smaller membership base, began to fill. Queues at peak times became common at popular locations. Amex has responded on two fronts: restricting access (removing free guest access for most US cardholders in 2023, introducing the three-hour pre-departure window) and expanding the physical footprint.

The expansion pipeline is significant. Salt Lake City opened in 2025. Newark opens in 2026 at 17,000 square feet — the largest in the network. Amsterdam opens in 2026, roughly 6,000 square feet. Boston follows in 2027 at around 20,000 square feet. A new concept called Sidecar — a smaller cocktail bar and small plates venue aimed at cardholders with tighter connections — opens in Las Vegas in 2026. This is Amex acknowledging that a full-service lounge experience is not always what a 45-minute layover demands.

Centurion Lounge vs the Rest of Your Platinum Access

The Centurion Lounge network is only one part of what the Amex Platinum lounge benefit covers. The card also comes with full Priority Pass membership, giving unlimited drop-in access to the global Priority Pass network. On top of that, UK cardholders receive 8 pre-booking entitlements per year (from 2026) specifically for participating UK Priority Pass lounges — useful for securing a spot in advance at busy UK airports. The card additionally grants access to Plaza Premium lounges and selected Lufthansa lounges (when flying on a Lufthansa Group carrier). In the UK, this matters because Heathrow T5 has no Centurion Lounge — your Platinum card accesses the Plaza Premium lounge and the Aspire Lounge in T5 instead. If you are routing through T3, you have the Centurion Lounge. If you are on a BA flight from T5, you are in a different tier of the product entirely.

Understanding which lounge your card actually opens at your departure terminal — before you reach the airport — is worth doing. Amex’s lounge finder at americanexpress.com will show you exactly what is available at each terminal, which cards are accepted, and current opening hours.
