Famously--or infamously, depending on who you ask--Saarinen introduced the concept of mobile lounges at Dulles, and these vehicles are still going strong today. (There are plans to move to an underground system at some point in the future.) The vehicles shuttle passengers from the main terminal to jetways to prevent exposure to the weather and jet fumes.
The main terminal was recognized by the American Institute of Architects in 1966 for both design concept and for the suspended catenary roof which allows for a totally open area with no visible columns or supports. (The roof is similar in technical concept to the Gateway Arch, believe it or not.)
Although more and more flights from the airport have increased traffic, congestion and security lines, the Saarinen designed terminal is still going strong. Hopefully future terminal buildings will be completed with the same type of passion and attention design.
