Caroline flew home today after her short jaunt to Dallas. The Phoenix Sky Harbor International Airport has been undergoing some renovations, two of the upgrades are outstanding. The first you cannot see in my photo, it is the paging and announcement system – it is crystal clear, you can actually understand what is being said! The other upgrade is shown above, the old CRTs with poor readability that were high overhead are gone and have been replaced with these large flat screens at eye level that make reading incoming and outgoing flights a breeze.
