They are the new are Recaro seats and are becoming the new norm around the world now, even full service carriers use these now.In Jan we flew the A321 from SYD to RAR. It was the most uncomfortable seat I have ever had on a flight and the plane was only around 60% full. The JQ seats feel like hard plastic and barely reclined. Awful for an overnight flight, especially one that arrives at 3.35 am at your departure point. However, a great destination, so it quickly made up for it. We flew back Jetstar via AKL on A320s which was a marginal improvement.
Qantas are taking the same seat albeit with clothing padding and a headrest on its A321s.
Bonza had the same seat as Jetstar but invested in a headrest which was half decent.
I feel like JQ could do with a headrest.
