Q: I'm flying out thursday morning. I'm not very scared but it's just my curiosity. also, will I have to go through customs when I get there or will I be going through those before I leave detroit?
A: You go through customs when you arrive in the country you're going to. You will be handed a little form to fill out while on the plane. When you get off the airplane you'll pick up your luggage, then get in a line-up(don't worry, you won't get lost, everyone else off the plane will be doing the same), hand the little form over to the customs officer, answer a few questions, and that should be it unless there's something they don't like about the answers you give. Vancouver airport is only mildly confusing. It isn't a really big airport. I've seen better and I've seen worse. Arriving at it is simpler than leaving. Count on an hour from the time you get off the plane till you're out of the place; maybe less, maybe more, depends on how busy it is at customs. Have a good time. You've picked a good season to visit Vancouver. I've heard the weather is supposed to be dry until well into August.
