I am planning to take a trip to Atlanta, GA, USA from Vancouver, BC, Canada. When I come back to Canada, I am going to be transferring somewhere inside the USA. So my departure airport is in the USA, my connecting airport will also be in the USA, and my final destination will be Canada.
Do I have to buy my duty-free item (probably a bottle of alcohol) at the connecting airport (likely going to be Seattle or Phoenix), or can I buy it from Atlanta and just carry it with me the entire time?
Another question, probably the first question I should ask: is there a duty-free shop that sells alcohol at the Hartsfield Intl. Airport in Atlanta?
I have been to international airports where they didn't have duty-free shops.
