Cathay Pacific Lounge: The Best Lounge at Heathrow T3
The Cathay Pacific First and Business Class lounge at T3 consistently gets mentioned as one of the better airline lounges in Europe, and for good reason.
The dining room operates like a restaurant: seasonal menu, table service, a wine list that holds up against city-centre options. The noodle bar (made to order) is a particular draw. Shower suites are spacious and stocked with Bamford products. First Class and Business Class sections are separate; both are good, but the First area is quieter.
Access requires a Cathay Pacific or Cathay Dragon Business or First Class ticket, or oneworld Emerald/Sapphire status.
American Airlines Admirals Club
American Airlines operates an Admirals Club at T3, with a dedicated First Class section for premium passengers. Access to the main Admirals Club is for Business Class passengers, Concierge Key holders, and Executive Platinum members; the First Class section is restricted to First Class ticket holders.
Full dining, a well-stocked bar, comfortable seating. Less refined than the Cathay lounge, but a solid option for transatlantic Business Class passengers.
Plaza Premium Lounge Terminal 3: The Independent Option
The Plaza Premium Lounge at T3 is the main independent option at the terminal, open to anyone via day pass, Priority Pass, or Curo package.
Hot food buffet, open bar, showers, and reliable Wi-Fi. During off-peak hours it is quiet enough to work in. This is where Curo walks T3 Gold package clients who do not have an eligible airline lounge.
No. 1 Traveller Lounge Terminal 3
No. 1 Traveller has a lounge at T3, smaller than their T5 space but the same format: buffet, bar, showers, comfortable seating. Day passes from around £35, also covered by Priority Pass and Curo packages.
How to Access a T3 Lounge Without Business Class
Both independent lounges at T3 (No. 1 Traveller and Plaza Premium) accept:
1. Day passes — typically £35–50, bookable in advance or at the door
2. Priority Pass, Lounge Key, or Dragonpass — covers Plaza Premium
3. Curo Gold or Platinum package — includes T3 lounge access with fast-track security and meet & greet
Curo selects the appropriate lounge for your specific flight and walks you there directly from fast-track security. New to the service? See what airport meet and greet includes, or browse the full Heathrow concierge page.
