United Airlines Boeing B747 400 seat review by Michael McAdam #26098

I flew this plane before UA had begun its conversion to new seats. Not a moment too soon! The first class seat was a major disappointment. Yes, it did go fully flat and allowed me to catch a few hours of sleep on the way to Tokyo, but I had to concentrate on not fixating as to how filthy the seat was when I slept. The upholstery is showing its age and there are stains -- unidentifiable to the naked eye -- ground into the fabric. There were still crumbs around the seat that did not look particularly fresh. I don't think it was the result of a poor cleaning in BKK but rather poor maintenance all around.
