Despite its size, the A350-1000ULR will carry only 238 passengers, giving it the lowest seating density of any Airbus A350. The four-cabin layout includes six enclosed First suites, 52 Business suites, 40 Premium Economy seats and 140 Economy seats.
Qantas has also developed a dedicated Wellbeing Zone between the Premium Economy and Economy cabins, where passengers can use stretch handles, follow guided movement programmes and access a hydration station during the flight. Cabin lighting, meal timings and seating layouts have been developed using research into sleep and circadian rhythms, aimed at helping passengers manage the physical effects of spending almost an entire day in the air.
