IAD was the best I have EVER seen it yesterday for a UA connecting pax.
We touched down at 3.16pm and cleared INS, collected bgs, gone through customs, passed the bags back to be cheked through to PHX, gone through security again and finally ploncked my fat ... in the RCC by 4pm. I was Very impressed.
In contrast to House, I have found that ORD can be hell at the wrong time of day. You knoe you have trouble when on final and can see another ac on final especially if they are an foreign carrier as you know which ever plane taxis faster gets to dump 300 pax in front of you.
