Cathay Pacific Business Class Lounge — Terminal 3, London Heathrow
The Cathay Pacific Business Class Lounge at Heathrow T3 is the larger of the two CX lounges on the upper level of the terminal, and the one most oneworld Sapphire and Business class passengers will use. It is a well-run, well-maintained room — quieter and more considered than most business class lounges at Heathrow, with a food offer that draws consistently positive reviews and showers that are among the better-kept in the terminal. It is not as exclusive as the First Class Lounge next door, but the quality differential is smaller than the tier names suggest, and for the majority of oneworld Sapphire members passing through T3 it represents a genuinely strong pre-departure option.
The lounge sits on the same upper floor as the First Class Lounge, accessible via the dedicated CX lounge lift from the T3 departure hall. It is a meaningfully larger space than the First Lounge, with a broader seating mix and a buffet-style food counter alongside the hot food offer. Access is via CX Business class ticket, oneworld Sapphire status, or Cathay Gold tier — a broader population than the First Lounge, but still a controlled and relatively calm environment compared with the independent contract lounges in the terminal.

The Lounge
The Business Class Lounge shares the calm, considered aesthetic of the First Lounge — dark tones, low lighting, generous seat spacing — but on a larger scale and with a slightly more practical layout geared towards a broader mix of travellers. The seating divides into a main lounge area, a dining section near the buffet, a bar counter, and a workspace zone. The finish is noticeably better than the independent contract lounges in T3 and has been well maintained since the lounge’s last refresh. It rarely feels crowded under normal CX T3 schedules, though peak long-haul morning departures can put pressure on the buffet area.
The noodle bar — the same made-to-order hot noodle counter found in the First Lounge — is present here too, and is the standout food feature. The overall atmosphere is quieter than the Virgin Clubhouse and more restrained than the Centurion Lounge, which makes it a good option for travellers who want to eat, work, or rest without distraction before a long-haul departure.
Food & Drink
The buffet covers hot and cold options rotating through breakfast, lunch and dinner service — a broader selection than the First Lounge’s à la carte menu, but with lower per-dish ambition. Quality is consistently above contract lounge standard: fresh, well-presented, and replenished reliably. The noodle bar is the highlight and operates throughout the day, producing made-to-order dishes that outperform anything on the buffet counter. Breakfast is the strongest meal period; lunch and dinner are solid rather than remarkable.
Drinks are fully complimentary including spirits, wine, beer and cocktails — the same policy as the First Lounge. The wine and Champagne selection is slightly less distinguished than the First Lounge but still above average for a business class product at a UK airport. Coffee is made to order at the bar. The overall drinks offer is better than the Centurion Lounge and comparable with the Virgin Clubhouse.
Showers
Shower suites are complimentary and shared with the First Class Lounge on the same floor — stocked with Bamford toiletries (geranium-scented) and widely considered the best shower facilities at any Heathrow terminal. The dark marble and gold fittings are exceptional. Book at reception on arrival. Towels and hairdryer provided.
Getting In
The most practically significant access route for UK readers is oneworld Sapphire via BA Silver status — a tier that at T5 gives access to the Galleries Club lounges only, with no upgrade path to Galleries First short of Gold. At T3, BA Silver unlocks the Cathay Pacific Business Lounge, which is a meaningfully better room than Galleries Club South or North at T5. This is worth knowing for BA Silver members who have T3 departures: the CX Business Lounge is the default option and it is a good one.
As with the First Lounge, access is tied to flying on a oneworld carrier from T3 — the status opens the lounge when you are departing on any oneworld flight, regardless of cabin, though confirming the specific cabin rule with the operating carrier is advisable if travelling in Economy. There is no day pass and no card-access route. If you are an Amex Platinum holder without oneworld status departing T3, the Centurion Lounge is your option — not the CX lounges.
BA Silver members departing T3 on any oneworld carrier — Cathay Pacific, Qantas, American Airlines, Iberia, Finnair — have access to the CX Business Lounge via oneworld Sapphire. This is a significantly better lounge than anything BA Silver unlocks at T5, and many Silver members are unaware the access applies at partner carrier lounges. Check that your oneworld Sapphire card or digital credential is accessible before you travel.
A strong business class lounge that punches above what BA Silver members are used to getting at T5. The noodle bar, complimentary showers, and calm atmosphere make it a genuinely comfortable pre-departure option, and the well-maintained finish sets it apart from the independent contract lounges in the same terminal. For BA Silver holders and oneworld Sapphire members passing through T3, this is the lounge to use — it is better than the Centurion Lounge for food and atmosphere, and better than most of what Priority Pass delivers in the terminal.
