It's never welcome news when a travel company is hacked – but especially not when it handles bookings, check-in systems, and other IT needs for around 140 airlines worldwide.

As carriers like Qantas, Cathay Pacific, Japan Air Lines and Malaysia Airlines all work to find out how much of their information was taken, what does this say about the state of cyber security in the industry, and could the airlines have even done anything to prevent it?

On this week's Australian Aviation Podcast, Jake and David examine the fallout of the Amadeus data breach, what it means for passengers and the impacted airlines, and what carriers should be doing to make sure their data is safe with third-party systems.

Plus, the next steps in Alliance's turnaround plan, more details about Vietjet's tilt at Australia, and will business jets be shut out of Sydney at night?

It had once seemed like it would never happen – but after decades of waiting, at long last, Western Sydney International Airport is open for business, with the first passenger flights taking off on Sunday and international services beginning on Monday.

Amid all the hype and celebrations, CEO Simon Hickey has forecast 10 million passengers per year by the mid-2030s and said WSI could supplant Kingsford Smith as Sydney's main airport. Is he right, or is it just wishful thinking?

On this week's Australian Aviation Podcast, Jake and Hannah recap the trials and triumphs of Western Sydney Airport's grand opening, ask what's next for Australia's newest international gateway, and declare an undying blood feud on a certain Jetstar A320.

Plus, how will Lim Kim Hai pay for his admitted wrongdoing as Rex's executive director – and are his fellow directors off the hook?

What began with a bang now ends with a whimper – Joshua Wander, former CEO of Bonza financier 777 Partners, has pleaded guilty in the US to a half-billion-dollar fraud scheme, thus ending the sorry tale of what once seemed a promising new contender in Australia's aviation market.

Wander now faces a maximum of 40 years in prison after the collapse of the 777 Partners "house of cards" – cold comfort, perhaps, to everyone left out of work and out of pocket by its role in the demise of the airline it had once bankrolled.

On this week's Australian Aviation Podcast, Jake, David and Hannah take a magnifying glass to the financial skulduggery of 777 Partners as we close the book on the Bonza saga.

Plus, with a global asset freeze slapped on the low-cost carrier, are Vietjet's plans for Australian expansion over before they began?
