When will IAH do something about terminal D?
There are plans out there for the terminal to be modernized. This includes adding an upper floor to accommodate larger lounges for the European and ME carriers. I'm not sure when this work is scheduled to start however.
The bigger issue is that the more recent improvements at IAH, Terminal E, and Terminal B South were funded jointly by CO and later UA. The airport authority probably doesn't have the money to do significant work on D all by themselves. I wish it were otherwise, but that's just how it is. There"s also just not much room to expand D to the East because of a taxiway.
