To test that metric, Qantas, the flag carrier of Australia, is embarking on a new campaign called Project Sunrise, which will test the fortitude of crews and passengers during the ultra long haul flight. This is one of the first times in which long haul flights covering distances of over 10,000 miles have been a feasible prospect for commercial air service. Perhaps for that reason, Qantas has approached the prospect of offering long haul service between Sydney and New York (a distance of 10,000 miles) and Sydney and London (a distance of just over 11,000 miles) very carefully. To gather data, Qantas is outfitting test subjects with wearable devices to monitor sleep patterns, food and beverage consumption and movement throughout the long haul flight. After Project Sunrise at Qantas wraps up, we may know the answer.
