The last couple of times through GE at Washington IAD things have seemed slow because the CBP agent needs your passport and asks questions. There’s a new setup - the check is right after the kiosks and before you claim any checked luggage. Previously one could go straight to customs checker at exit from kiosk, with rarely a question asked (except about food). Now it’s more like the regular check for non-GE folks.

Any ideas why? Is this occurring in other airports too?
