Let's hope the Platinum seating benefits "evolve" and improve as well. Many flights I took this year have been in almost full cabins with a handful of free seats, and it is frustrating to be one of the pax packed like sardines into the first 4-5 rows of Y, while further down the plane backpackers are stretching out enjoying the prized empty middle seats.
Allowing more silvers and golds free access to the coveted comfort seats is not going to improve this phenomenon.
