For a bit more clarity - there are no tolls if you are going straight from the beltway to Dulles Airport. If you use the non-Dulles lanes (you want to get to stuff between beltway and Dulles), you have to pay tolls.
So just watch the signs and be sure to take the left Dulles-only exit immediately after you get onto the access road.
So if I'm going to the airport, get in the two left, seperated lanes for no toll and do the same on the way out? It was a bit confusing for the first time.

No, only one lane makes the cutover, as you can see here. It's not a special lane on the tollway, its a separate roadway. Leaving, take the exit from the airport that's labeled for the Beltway, the left lane here.......
