This has air travel fanatics and architecture junkies understandably upset, but we recently traveled through T3 and found the experience of the place to be insufferable. Large international flights should not be leaving out of this terminal. Delta usually only has one or two agents staffing the check-in desks, and the before-security area is so small that the terminal regularly becomes a mess of people waiting in lines going all directions. We have seen the line for security go out the door; good thing it was a sunny, warm day! And have you seen the ceiling? It leaks constantly, from many areas. If you weren't familiar with the history of the structure, you might wonder why Delta was operating out of such a inefficient and deteriorating space.
So although it saddens us to see it go, we understand that it might be time to have a fresh start with Terminal 3. After all, JFK will always have TWA's T5 and there's still the old Terminal 2 that once had Braniff, Northwest and Northeast, not to mention Terminal 6 of National Airlines and Terminal 7 of BOAC.
