Qantas has announced that they will be changing one of their most popular flight paths.
In addition, the QF 2/1 service will from March 25 next year use an Airbus A380 while Qantas' second daily Sydney-London service will continue to use an A330.
Qantas Group Chief Executive Officer, Alan Joyce told the media via a teleconference that the changes will also help the airline's freight business.
Joyce adds, however, that passengers travelling to other European destinations will still be served via the Dubai hub through codeshares on Emirates' services.
Qantas had already announced that it was replacing its Melbourne to Dubai to London service with its ultra-long-haul Melbourne to Perth to London Boeing 787 Dreamliner flights.
"Customers of both airlines will continue to benefit from the power of our joint network, from our respective products, and reciprocal frequent flyer benefits".
"We get a network into Europe that we can operate comfortably, we know that's valuable, our customers love it".
Customers with existing bookings impacted by the changes will be re-accommodated onto the airlines' new services or will be given the option to change their flights.
Qantas does not disclose the commercial arrangement of its partnership with Emirates, which analysts have said was not as successful as originally anticipated five years ago.
The changes mean passengers in Australia will be able to fly to Europe via either Singapore or Perth on Qantas.
The key change to the partnership will see Qantas's daily A380 service to London re-routed via Singapore.
"Emirates altogether get 1.6 million passengers from Qantas on their entire network".
Australian aviation firm Qantas Airways announced it will add services to Changi Airport starting 25 Mar to 27 Oct 2018, the northern summer season.
The choice of three hub options between UK/Europe and Australia - Dubai, Perth and Singapore.
For Emirates' customers, the partnership opens up access to over 60 Australian destinations that Emirates does not serve, and for Qantas' customers, it gives access to over 40 cities in Europe, the Middle East and North America, not served by Qantas.
