The seat armrest is a property of the seats (which are chosen by the airline) rather than a property of the aircraft, so you should blame your choice of airline rather than the perfectly fine 777. I often fly on Air France&#x27;s 777s between Osaka and Paris and the armrests go up fully.<p>In terms of comfort my best flight in coach was on a Korean Airline A380: spacious and quiet; my worst on a JetStar A330 in cattle-like configuration. But I won&#x27;t blame&#x2F;praise Airbus: even though quietness is certainly a quality of the aircraft, the seat layout is absolutely a choice of the airline, so I now avoid JetStar like the plague.
