The $6 billion fix: how Sydney Airport's new terminal link will change the way you fly

Sydney Airport has just locked in the architects behind London Heathrow and JFK to lead a massive $6 billion overhaul.

The centerpiece? A landmark link between T2 and T3 designed to create a "seamless" journey for 72 million passengers each year.

Here is exactly what the master plan means for your future flights - and those dreaded connection times.

Sydney Airport will look very different in 2045 to what it does today.

A huge expansion will have regional, domestic and international flights brought under one roof.

T2 and T3 domestic terminals are being combined into one mega-terminal which will cater for both local and overseas flights.

This means there will be two areas you can catch an international flight from - T1 or the expanded, new "super terminal" which will take in T2 and T3 - so the chances of having to catch a shuttle bus, taxi or train between the T1 and the T2/T3 areas will be minimised.

Twelve new swing gates will support both domestic and international operations. A swing gate is a flexible gate that can be used for either domestic or international flights, depending on scheduling requirements.

The new super terminal will be something to behold. No more being dropped off at the wrong terminal and dashing across the carpark between the two, or walking across to T2 for some fast food, only to realise you need to dash back to T3 for your flight.

Under the new design, you will be able to walk behind a security screen between the two terminals - you won't have to exit and enter security a second time.

T2 is also being upgraded with some cult food options, with 14 food and beverage outlets on the horizon, including an Icebergs outlet inspired by the iconic Bondi venue, as well as Lotus Dumpling Bar, cult ramen bar RaRa, and retro burger joint Slim's Quality Burgers.

It won't just be the swanky new super terminal coming on board in the years ahead. A number of upgrades will be undertaken to cater for the airport's projected growth.

If you think Sydney Airport is already busy, think again. The 72.6 million people expected yearly through the terminals by 2045 is a 75 increase on the passengers today.

There will also be new freight areas, hangars and ground transport facilities, as well as a new link road. Airfield upgrades will include new taxiways.

And sustainability is reportedly a big factor in Sydney Airport's decision-making process.

Airfield upgrades will allow the airport o accommodate new and improved aircraft that are quieter and more efficient, to help reduce the airport's carbon footprint and its noise impact on its neighbours.

The airport will also work to improve decarbonisation and climate resilience, which includes a focus on sustainable aviation fuel.
