By Nahrain John @karryontravel28 Mar 2018First Class, Business Class, Premium Economy Class, Economy Class and quite possibly, sometime in the near future, travellers could find themselves hanging out in, ‘Exercise Class’. Qantas is considering a completely different look for the interior of its ultra long-haul aircraft that could reduce passenger fatigue and provide sufficient space for stretching out on non-stop 20-hour flights, The Australian Business Traveller reported. Chief Executive Alan Joyce told media after touching down in the London on the first direct flight from Perth, that the carrier may utilise in-flight freight areas to introduce either a dedicated ‘exercise class’ or a ‘sleep class’. As the names suggest, an ‘exercise class’ would be for guests to carry out their DVT prevention movements, and the ‘sleep class’ would be for sleeping. “We are looking at do we need and should we have four classes? Is there a new class that’s needed on the aircraft?” Alan Joyce, Qantas Chief Executive The airline is working with aircraft manufacturers, Airbus and Boeing, to design the perfect ultra long-haul aircraft, but Joyce recently admitted to encountering a few challenges along the way. Qantas CEO Alan Joyce arriving in London on the first direct flight from Perth. Among the dilemmas is ensuring the aircraft can operate as far as Sydney-London or Melbourne-New York, while also being practical enough to be used on regular routes such as Sydney to Singapore and Sydney to Hong Kong. “It can’t be too heavy, it can’t be specialised too much so it’s not feasible elsewhere. That’s going to be a challenge,” Alan Joyce, Qantas Chief Executive Meanwhile, Qantas revealed earlier this year that it plans to invest more money in new aircraft, including the delivery of four Airbus A321NEOs.
