Ranted and rated, here is our expert guide to the London loungescape for Oneworld flyers at Heathrow T3.

Terminal 3 of London’s Heathrow Airport is home to most Oneworld airlines flying into and out of the British capital – a roster which includes American Airlines, Cathay Pacific, Finnair, Japan Airlines and Qantas.
Even British Airways, which has its own busy hub at Terminal 5, maintains a schedule of European and longer-range international flights departing from T3.
(However, Malaysia Airlines, Qatar Airways, Royal Air Maroc and forthcoming Oneworld member Oman Air all fly exclusively out of T4.)
As a result, Heathrow T3 is thronged with passengers on Oneworld airlines who are either travelling in business class or holding lounge-worthy Oneworld Sapphire status.
And they’ve got four business class lounges to choose from: American Airlines, British Airways, Cathay Pacific and Qantas each offer a T3 foothold.
With that in mind, here’s the Executive Traveller cheat-sheet for choosing the best Oneworld business class lounges at London Heathrow Terminal 3.
London Heathrow T3 Oneworld lounge access
So here’s something that savvy travellers and frequent flyers know, but many others remain unaware of: depending on your class of travel or frequent flyer status, in most cases you can use the lounge of any Oneworld member airline, not just that airline’s own.
For example, business class or Oneworld Sapphire passengers flying on American Airlines or British Airways from T3 don’t have to make a beeline for the AA or BA business class lounges. They’re fully entitled to visit T3’s Cathay Pacific or Qantas lounges (and indeed, they should).
The same goes for airlines which don’t have their own lounge at T3, such as Finnair and JAL. Even if airline check-in staff direct you to the Qantas lounge, you’re not actually obliged to head there: you can visit any of the other Oneworld business class lounges at T3.
Indeed, should you have the time or the inclination, you can sample all of T3’s Oneworld business class lounges, as they’re located within a few minutes’ walk on one another.
So who’s allowed into London Heathrow T3’s Oneworld lounges?
Business class passengers on any Oneworld airlines departing from T3, and at the time of writing those are:
- American Airlines
- British Airways
- Cathay Pacific
- Finnair
- Japan Airlines
- Royal Jordanian
- SriLankan Airlines
- Qantas
Premium economy and economy passengers holding Oneworld Sapphire frequent flyer status with any Oneworld member airline, including
- American Airlines AAdvantage Platinum
- British Airways Executive Club Silver
- Cathay Pacific Gold
- Finnair Plus Gold
- Japan Airlines Global Club / Mileage Bank Sapphire, Global Club Crystal and Global Club
- Malaysia Airlines Enrich Gold
- Royal Jordanian Gold Sparrow
- SriLankan Airlines FlySmiLes Gold
- Qantas Frequent Flyer Gold
- Qatar Airways Privilege Club Gold
Those frequent flyers can also bring one guest into the lounge, provided that guest is travelling on a Oneworld member airline flight (however, business class travellers have no guest privileges).
Now that we’ve got your Oneworld lounge access sorted, which Oneworld lounge at London Heathrow T3 should you visit?
1. Cathay Pacific Business Class Lounge
Location: Lounge C, near Gate 11 (open 5:30am to 9pm)
The Cathay Pacific Business Lounge is easily the best Oneworld business class lounge at Heathrow T3.
Superb food and drinks, spacious well-appointed showers, plenty of room and comfortable seating options plus tarmac views make this the go-to for Oneworld business class passengers and frequent flyers.
Essentially a scaled-back version of Hong Kong’s The Pier Business Lounge, you can tuck into freshly-prepared Asian delights from The Noodle Bar...
... or an array of hot and cold food from the buffet (our picks on a recent visit: honey sriracha chicken wings and carrot, beetroot and edamame salad), while a ‘pantry’ area tempts with light bites and sweet treats.
Further along is a tended bar with wines, spirits, Champagne and cocktails plus treats such as bubble tea.
Cathay’s London lounge boasts a wide variety of seating where you can maker yourself at home.
The far end of the lounge has a cosy ‘den’ area to one side, with a cluster of work-friendly booths by the window.
So stow your cabin bag in one of the luggage lockers near the shower area, relax, and make yourself at home.
Our recommendation: no matter which Oneworld airline you’re travelling with (and especially if that airline directs you to the American Airlines or British Airways lounges), the Cathay lounge should be your first port of call, and it’s probably the only lounge you need to visit.
2. Qantas London Lounge
Location: Lounge B (open 8am to 9pm)
Conveniently located next door to the Cathay Pacific lounge, Qantas’ London outpost elegantly channels a ‘British private club’ vibe across its two floors.
The upper level contains an eye-catching circular bar, while the ground floor is largely given over the à la carte dining room and and a well-stocked gin bar.
And those are the two drawcards at Qantas’ London lounge, even for short-term visitors popping in from another lounge.
![Stick to the ground floor of the Qantas lounge for à la carte dining and the globe-trotting gin bar.](https://www.executivetraveller.com/photos/view/size:960,540/66beb3372b1c46c18141b8d0dd799465-qantas-london-heathrow-lhr-t3-lounge-review-11.jpg)
Evenings are the best time to visit, as the à la carte service begins around 6pm (ahead of the 9pm departure of QF2 to Sydney via Singapore).
Most diners will opt for the ‘signature’ salt and pepper squid with green chili dipping sauce and aioli, although it’s not up to the same delectable standard as its siblings at Qantas’ first class lounges in Australia.
Also on the dinner menu for mains during our visit:
- Heirloom tomato, watermelon, chilli salt, mint and basil salad
- Salad of green tea noodles with poached chicken, cucumber, mint, red cabbage, tofu and sesame dressing
- Japanese pumpkin chicken curry pot pie with cabbage slaw
- Lasagna with tomato sugo and shaved parmesan
You can bookend your dinner by sampling choice tipples at the Gin Bar, which range from British classics and modern hometown heroes like Copper House and Sipsmith to world-class Aussie contenders including Four Pillars and Brookie’s.
3. British Airways Galleries Club Lounge
Location: Lounge F (open 5am to 10pm)
While a recent refresh uplifted BA’s T3 business class lounge, it can still be incredibly crowded and noisy, especially in evening peak times.
There’s little reason to steer your way here instead of the Cathay or Qantas lounges, although BA’s T3 lounge does have a decent buffet spread (just part of this is shown below) plus a selection of self-pour spirits, if that’s your thing.
(But if you prefer Champagne over Prosecco, Cathay is again your go-to with Laytons, while Qantas pours Petaluma Croser sparkling.)
At least younger flyers can be kept briefly entertained by the PlayStation 5 console in the Kids Zone room plus an ice-cream and popcorn stand.
4. American Airlines Admirals Club
Location: Lounge H (below the Virgin Atlantic Clubhouse; open 5am to 7.30pm)
There’s no reason to visit American Airlines’ LHR T3 Admirals Club unless you’re a member of the paid Admirals Club lounge program or hold an American Airlines credit card with lounge privileges, in which case this is your only lounge option at Heathrow.
This is not a patch on American Airlines’ Flagship international business class lounges in the US.
Sad and tired, old and cold, it’s more like a hospital waiting room from the 1980s, while the buffet is an cursory exercise in getting away with as little as possible.
In short: no. Just no.

Can't argue with any of this and LOL at the honest description of the AA lounge, this is basically like a very old school Qantas Club in that it's only for 'Club' members, any AA passenger in business class or who has OneWorld Sapphire status visit the AA lounge needs to have their head read.

Great review! And I love the description of the AA lounge food, just brilliant “a cursory exercise in getting away with as little as possible”! Too funny.
But overall you have nailed the business class oneworld T3 lounges. How about for us OWE fliers, you also include a comparison of the First class options, in Cathay First and BA Galleries First. Could even at a stretch include The Qantas Lounge given that Qantas likes to see this as a quasi first lounge and offers real champagne and a reserves seat to First and OWE/P1/CL customers.
These guys popped up a great review of the Cathy First lounge food only yesterday and have a BA First review too

But while a great and detailed review of the food, it would be good to have an Exec traveller holistic comparison, including the seats, views, service, showers, drinks etc.
Is that something you guys can do?

This is a very helpful review as we are flying out of T3 in a week or so.
If our Qantas upgrade comes through we will see how these are in the morning... if not, there are the lounges through Amex :)
Thanks again for a helpful and interesting review.

Flew out of T3 with JAL in July and did a bit of lounge hopping with a visit to the Qantas, Cathay and American lounges and agree with your review. The AA lounge reminded me of the cafeteria on a European ferry service but I wanted to check one out as I hadn't been to one before. Was going to go to the BA lounge but time ran out and I had been to the T5 one last year.

Prior to Qantas opening their lounge passengers were sent to the BA lounge.. this was really z grade when it came to the food offerings, eg last time I was there a chilli con carnie (minus the chilli), and an awefull beef stew mince based). Wines offered had a largely South African base.. and most were very good. This lounge when compared to BA's offering in Terminal 5 was really a low grade.
