Just traveled on the "new" J with new fabric. Definitely better than the old fabric in terms of comfort, but I was on KPH, and the fabric was already looking worn out. I don't know how long the specific plane's been using this fabric, but i'm guessing at max for a year. I can't imagine how it'll be another year or two down the road...
