I flew with Qatar Airways from Adelaide to Doha and then to London, and on the long-haul segments I noticed a headrest feature where the sides could be bent inward to support and “hold” your head in place, which made sleeping much easier.
I’m now planning a trip to London with Qantas. The long-haul legs will be Singapore to London (QF1 on an A380-800) and London to Perth (QF10 on a Boeing 787-9).
I’m wondering if Qantas aircraft have a similar adjustable headrest feature for economy seats, like the one I experienced on Qatar Airways.
