Our first impressions were that it was a nice enough terminal, nothing to write home about, but adequate. However, the dust and dirt in every nook, cranny, underside of cement beams, window sill, blind and air vent became hard to ignore. My techs at work have to deal with HIA's (Hospital Acquired Infections) but now I know there must be AIA's (Airport Acquired Infections), because I'm sure the air conditioning is carrying germs, viruses and bugs all over the terminal. It looked like the maintenance crew went on strike in 2012 and never returned. We've never been so thankful to have as short a layover as we had.
In the future we will avoid DFW at all costs because we value our health. I highly recommend our friends, family and followers do the same, if you want to avoid getting sick. All you bloggers and vloggers who publish Top 10 and Worst 10 lists: if you have one for airports, DFW has to be one of the "Worst." But, you might not want to visit to confirm, I'm just sayin'.
