The Lounges
The BA Galleries operation at T3 is two lounges in one building: Galleries Club for Business class and Silver/Sapphire passengers, Galleries First for First class and Gold/Emerald. Both share an entrance lobby, corridor, toilets, showers and spa — only the main seating areas are separated. The combined footprint is the largest of any lounge at T3, which in practice means it is rarely as crowded as the equivalent lounges at T5, where BA’s volume of traffic is much higher. This is the lounge’s single most consistent advantage: more space, more seats, and more natural light than most of the competition in the terminal.
The design is recognisably BA — muted tones, corporate art, the same general aesthetic as the Galleries lounges at T5 — but housed in an older building that limits the floor-to-ceiling windows found at T5 South. Windows run along one side of the lounge and let in reasonable natural light. The room was last refreshed in 2023 and holds up acceptably, though it reads as functional rather than aspirational. The quiet end of the lounge — furthest from the entrance — is consistently the least busy and the most practical for work or a longer stay.
Food & Drink
Food is ordered via QR code at each table or through the BA app — the table service model that replaced the buffet and has been retained as the permanent format. The menu covers breakfast through to dinner and rotates across the day. Hot dishes, salads, cold plates and pastries are all available depending on the time of visit. Quality is consistently reported as adequate and occasionally better — BA’s Heathrow lounges are known for strong curry and hot lunch dishes in particular, and T3 follows the same format as T5. The à la carte dining room at the far end of the First lounge is available only to BA First ticket holders; Emerald members on partner airlines use the main lounge food service.
Champagne is available in both sections but requires asking a member of staff — it is not self-serve. The bar is self-pour for wine, beer and spirits. The overall drinks offer is adequate rather than distinguished; the Qantas and Cathay lounges both offer more considered bar programmes.
Showers
Showers are complimentary and shared between both lounge sections, accessible via a corridor off the main entrance lobby. Elemis toiletries are provided. The facilities are functional and clean but lack the premium finish of the Cathay Pacific or Qantas showers — BA’s T3 shower rooms are consistent with the T5 experience: competent but uninspiring. Pre-booking via the BA app is the recommended approach; first-come, first-served on the day at reception.
Getting In
You do not need to be flying BA to use these lounges. Any oneworld Business class ticket entitles you to the Galleries Club; any oneworld First class ticket or Emerald status on a qualifying oneworld departure from T3 entitles you to Galleries First. This covers departures on Cathay Pacific, Qantas, American Airlines, Iberia, Finnair, Royal Jordanian and any other oneworld carrier operating from T3. In practice, most oneworld Emerald members at T3 use the Cathay Pacific First or Qantas lounges instead — but the BA lounges are the early-morning fallback option from 5am if those rooms are not yet open.
BA Silver members on a oneworld Sapphire redemption have three Sapphire-eligible lounges at T3: the Cathay Business Lounge, the Qantas Lounge, and this one. The BA Galleries Club is the weakest of the three on food, bar and atmosphere — but it opens at 5am alongside the AA Admirals Club, before Cathay (5:30am) and Qantas (6am). For very early morning Sapphire departures it is the only option with reasonable food service from opening.
The weakest of the oneworld lounge options at T3 for Emerald and Sapphire holders, but a solid and spacious fallback — particularly for early morning departures before the Cathay and Qantas lounges open. The QR-code ordering system and table service are a genuine improvement on a self-serve buffet for a quieter visit. The separate First dining room is a meaningful benefit for BA First passengers. For everyone else with Emerald access at T3, head to Cathay or Qantas first and treat this as your backup.
