Saw the Jets take on the Kings on December 29th, 2011. Our seats were in row 7; the last row in section 215.
215 gives you a pretty good view of the ice. It was hard to see the puck in the far left corner; and that will go for all people sitting in each of the four corners. By no means are the corners ever the most desirable seats to sit in at hockey and basketball games.

You can avoid that problem by sitting on the sidelines of the 300s. I usually sit up there for games and the view has always been great; you won't miss any of the action although it becomes hard to make out who the players are at times.
Jets games are also not for those with empty pockets so expect to spend some serious coin at this venue.
