JFK arrivals is brilliant.

You will be met at the door and escorted into the immigration hall. You'll be placed at the front of the line for the machines if needed, and then escorted to the front of the line if you need to see an officer. They will then escort you to baggage claim if needed and handle your bags for you, and take you to the front at customs. If you have a driver, they will coordinate the handoff with him, and if you need them to they even are able to get you to the front of the general taxi queue outside.

Just top notch.

I should also add that regarding the lounge at JFK, by comparison, the BA Concorde Room is leagues nicer. The bathrooms at the AF lounge are atrocious.
