It's the beginning of the end for Qantas' superjumbo: so what's coming next?

Qantas' beloved double-decker plane is preparing for it's final descent in 2028, signalling the end of an era for mega-jets in Australia.

The national carrier is phasing out its fleet of 10 Airbus A380-800 aircraft four years early, but travel experts are reassuring Aussie passengers that this won't reduce seats available on major long-haul routes.

Australian Travel Industry Association (ATIA) chief executive Dean Long said the A380 earned its fans as a "gamechanger" plane.

But he said the incoming Airbus A350-1000s and Boeing 787-9 Dreamliners may be even more popular.

"The A350s and 787s replacing it are quieter again, with better cabin pressure and humidity, so most flyers will notice the upgrade rather than the loss," he said.

"Give it 12 months and today's A380 nostalgia will be next year's A350 loyalty."

Mr Long said the ATIA was not expecting fares to rise as a result of the fleet changes, saying the newer models are "being deployed specifically to maintain and grow capacity on key ports like London and Los Angeles".

Qantas has more than 160 next-generation aircraft on order, including ultra-long-haul planes to take over major international routes.

The A380 was popular for its spaciousness, but the newer A350s and 787s are quieter with better cabin pressure, meaning passengers step off the plane feeling fresher after a long-haul flight.

The next wave of Boeing 787-9 Dreamliners on order will feature sliding privacy doors and 80-inch lie-flat beds in Business Class.

In 2028, Qantas will receive the first of 16 new Airbus A321XLR aircraft, servicing domestic and short-haul routes.

These planes also offer a lie-flat bed, as well as sliding privacy doors and a 19-inch screen in Business Class seats.

Qantas is executing a fleet-wide "premiumisation" of their planes, shifting from 19 per cent density of premium seats to around 30 per cent by 2031.

Economy travellers will also benefit from the new fleet, with more spacious overhead lockers and larger screens.

Qantas chief executive Vanessa Hudson said the new aircraft will be more fuel efficient.

"That's not just good in terms of cost from a fuel perspective, but it's also an incredibly important part of delivering against our sustainability targets," she said.

"We're looking forward to seeing this new fleet evolve and change over time."
