It's sad, I know, but my experiences flying to another country have been limited to once, when I was 14..... we will not get into how long ago that was :evillaugh When flying from Canada to LAS, from a Canadian International Airport, do they do customs screening here in Canada? Or is it done at the first point of entry in the US? Or is it done at your final destination? How long does it usually take? We will have carry on. I've searched US Customs and Canada Customs sites and can't seem to find the answer. Thanks for your help.
