Priority Pass membership with no stated visit cap, plus the Amex lounges. About 17 UK lounge visits a year covers the £650 a year fee, valued at the £38.86 average walk-in price across the 35 Priority Pass lounges we have verified.
Priority Pass covers 43 of the 55 UK lounges we list, across 19 airports. See every one of them, with prices.
At Heathrow specifically, American Express’s own lounge page lists Platinum Card entry at the Centurion Lounge in Terminal 3, the Plaza Premium lounges in Terminals 2, 4 and 5, and the Blush Lounge in Terminal 4 — and Priority Pass entry at the No1 Lounge in Terminal 3 and Club Aspire in Terminal 5. Entry at the Terminal 3 and Terminal 5 lounges is from three hours before departure, a limit Amex waives for Platinum cardholders with a confirmed connection. A second Centurion Lounge has been announced for Terminal 5, due in 2028.
What American Express actually says
Quoted from the card’s own product page on americanexpress.com, checked 8 October 2026. We quote rather than paraphrase because the difference between “access” and “discounted access” is the whole story on this page.
Complimentary access to over 1,550 airport lounges across more than 140 countries worldwide.
The main Cardmember and the Platinum Supplementary Cardmember may bring up to one guest into the lounge at no cost.
Any additional guests will be charged a fee at the prevailing rate to his or her American Express Platinum Card.
8 complimentary lounge pre-booking entitlements to use per calendar year, between 1 January 2026 to 31 December 2027.
Representative example as published by American Express: 685.3% APR variable, with a purchase rate of 29.1% p.a. variable, on an assumed credit limit of £1,200. Fee: £650 a year. Figures change — check the issuer’s own page before acting on anything here.
What the benefits list does not tell you
The pre-booking cap is the real limit, not the visits
Amex does not publish a cap on how many times you can walk into a Priority Pass lounge. What it does cap is pre-booking a UK lounge: eight entitlements a calendar year for 2026 and 2027, up from four in 2025. At a busy UK airport at 06:00 that distinction matters — Priority Pass entry is subject to availability, and the thing that guarantees you a seat is the booking you have already made. Nine early flights out of the UK in a year and the ninth is a queue.
One guest free, then full price
You and a Platinum supplementary cardholder each get one guest in free. Anyone beyond that is charged to your card at the lounge’s prevailing rate. A family of four is one cardholder, one free guest and two paid entries — which is how a “free lounge” card ends up costing £50 at the door.
Amex lounges are not Priority Pass lounges
At Heathrow the card gets you into the Centurion Lounge in Terminal 3 on the card itself, and into the Plaza Premium lounges in T2, T4 and T5 and the Blush Lounge in T4 on the card too. The No1 Lounge in T3 and Club Aspire in T5 are entered on the Priority Pass card instead. Different routes in, different guest rules, same wallet.
Before you count on it
Check the lounge, not just the card
Every one of these cards works through a lounge network, and networks drop lounges. The question that actually matters is whether your airport’s lounge is in it on the day you fly — our Priority Pass list and DragonPass list both go lounge by lounge.
Availability is not the same as access
Priority Pass entry is subject to space. At a UK airport at 06:00 the lounge can be full regardless of what your card says, which is why pre-booking entitlements are worth more than they look.
Compare it against just paying
The average walk-in price across the 35 UK Priority Pass lounges we have verified is £38.86, and the cheapest departures lounge is £27. If you fly twice a year, paying at the door is usually cheaper than any annual fee on this site.
Or buy the membership directly
You do not need a credit card to hold Priority Pass — you can buy it outright, and our break-even calculator works out whether that beats paying per visit for the way you actually fly.
Frequently asked
Does Amex Platinum give unlimited lounge access in the UK?
American Express does not publish a cap on visits, and describes the benefit as complimentary access to over 1,550 lounges worldwide. What is capped is pre-booking a UK Priority Pass lounge — eight entitlements per calendar year for 2026 and 2027. Entry without a pre-booking is subject to availability.
How many UK lounges does Amex Platinum get you into?
Priority Pass covers 43 of the 55 UK lounges we list, across 19 airports. On top of that the card itself opens the American Express Centurion Lounge at Heathrow Terminal 3.
Can I bring my family into a lounge on Amex Platinum?
One guest free, per cardholder. The main cardholder and a Platinum supplementary cardholder each get one free guest; any further guests are charged to the card at the lounge’s prevailing rate.
Is the £650 fee worth it for lounges alone?
On lounge value alone you would need about 17 UK visits a year to cover it, using the £38.86 average walk-in price across the Priority Pass lounges we have verified. Almost nobody buys this card for the lounges alone, and we are not in a position to value the rest of it.
