I have a domestic-domestic connection at Dulles Airport in October with United, and my luggage will be checked through. I am travelling with one companion and our layover is scheduled to be 6h 45m in length - our plane lands in Washington at 3.20pm and our connection leaves at 10.05pm.
I was just wondering if there is any way to see a little of DC while we are connecting. I am aware that Sterling is quite a bit outside the city and I've never transited at IAD before but given the times of day and the length of the layover I thought a short trip *could* be viable.
Are there any feasible public transport options? If not, how much does a cab cost to Downtown for 2 and how long will it take.
