The upgrade is very much needed. We flew back from MIA in J last week and both of our seats had issues. In particular, the touch pads for seat adjustment were virtually inoperable and one had to be manually placed in bed mode and manually re-set to seat mode. The crew also couldn’t get it high enough to trigger the green light for the landing position. The bulkhead window seat had 3 storage boxes, one of which kept springing open and the other two were very reluctant to open. The alignment between the footstool and seat panels had a distinct drop and, despite trying to improve the alignment, the combination of tired seat and poor touch controls made it impossible. The sooner they are refurbished the better. Does anyone have a good estimate of how long it will take to do all 12?
