Hi Steve,
None of the 747s have had a cabin refresh recently. Most have Prime (new First) and all have the standard 2006 Club seat and year 2000 WT+ and WT cabins with Rockwell Collins IFE. It's AVOD but is starting to show its age. Old doesn't always mean tired though. The 747 fleet is a mixed bag. Some aircraft are crying out for a spruce up and others have quite decent interiors. Just luck of the draw which one you'll get!
Most of the fleet will undergo a refresh starting next summer and this will take about a year I think.
