With several daily flights from Qantas, Cathay Pacific, American Airlines and British Airways, London Heathrow Airport's Terminal 3 is something of a de facto hub for Oneworld carriers.
And as it happens, most of those airlines are working on new or radically revamped lounges which will progressively open from mid-year to early 2017.
In August we'll see fresh first class and business class lounges for Cathay Pacific.

The combined lounges will also be around 30% larger than before, with a footprint extending the space previously occupied by Singapore Airlines’ SilverKris lounge, which has now shifted into Heathrow’s Star Alliance T2 hub.
Watch for a Pier-style a la carte dining room and cocktail bar in the London first class lounge, and a 'sit and slurp' Noodle Bar (below) in the business lounge.
Towards the end of the UK summer American Airlines will cut the red white and blue ribbon on its made-over Arrivals Lounge.
Part of the US carrier's US$3 billion overhaul of its premium lounge network, passengers will enjoy new private showers and dressing areas with a valet pressing service...
... plus "an improved food and beverage service."
However, a spokesman for American Airlines tells Australian Business Traveller that there are currently no plans for AA's T3 departures lounges (below) to be refurbished, given that they were "most recently refreshed in 2010".
Of course, for Aussie travellers the main drawcard will be the all-new Qantas London Lounge.
Slated to open in March 2017, the split-level lounge will be conveniently nestled between the Cathay Pacific and British Airways lounges.
Head upstairs for the wine and cocktail bar, plenty of relaxed seating and views across the tarmac.
Stay downstairs for the "Rockpool menu and dining experience", which will use a seasonal menu to showcase British and European produce.
The 230-seat lounge will adopt the same integrated 'premium passenger' approach as its Singapore and Hong Kong siblings, rather than offer separate first and business class zones as seen in Los Angeles.
However, it's expected that additional services – such as free clothes pressing, first dibs on shower bookings and some 'off-list' wines and champagne – will be available to travellers in first class along with members of the exclusive Chairman's Lounge and Platinum One frequent flyers.
