I noticed when I was at the airport this weekend that they have started the next round of improvements starting with Concourse B (United & Southwest) and then moving over to Concourse A (American, Continental, Delta). I've always disliked the low ceilings in the concourses so this will be a major improvement with the skylights. I really like what they have done with the security area in the main terminal and hopefully the same finishes will be used in the concourses. I know the bathrooms have needed some work for a long time.
