I flew Premium Select last week, AMS to BOS. I usually fly premium economy. The seat was nice, the food seemed a little better, but the difference for me was the noise canceling headphones that allowed me to actually watch a movie and be able to hear it…ear buds never work. My seat mate made lots of trips to the galley for alcoholic drinks and snacks. I paid for the upgrade with miles, but doubt I would do it again.
