I know these travel questions have been discussed many times and I thought I had a good route figured out and it seemed a no brainer to fly into Edmonton when touching down in Canada for a sheep hunt. Unfortunately it is nearly impossible for me to find a flight which touches down on Canadian soil in Edmonton without going through another Canadian airport. It appears that Calgary may be the next best port of entry and then fly on to Edmonton. Is this a good Port of entry (I already know to stay away from Toronto and Montreal) and how much of a layover do I need before the flight to Edmonton to clear customs with firearms? Returns to the US seem to go through Denver or Chicago and how much time do I need in these airports when returning from Canada before my connecting flight, or is it just like any other TSA check point. I ask because a good flight returning home has a 54 minute layover in Denver which doesn’t seem like enough time to collect bags and go through US Customs.
