The US immigration and customs pre-clearance at Canadian airports is news for me, and I think that's just terrific. Great idea to allow for such procedures, and that definitely allows me to be more relaxed about the connection.
After checking in for your flight, you go through US passport control prior to security screening. After security, you will be in a secure area of the airport where the gates are used exclusively for departures to the USA. It's a nice system that generally makes things more efficient for the airlines, for passengers, and for US CBP
. My experience (as a US citizen) is that entering the US via Canadian pre-clearance ports is pretty easy. I've heard many people on this board and elsewhere say that flying from Europe to the US via YYZ
or other Canadian airports is easier that making the same connection at American ports like JFK
. Certain Canadian airports allow you to bypass Canadian immigration and go straight to the USA pre-clearance area. I've only done it once--making a KL
connection at YVR
--and it was pretty slick.
