I'm trying to jumpseat on UA645 IAH-YYC on 7/19/15. My carrier has full reciprocal JS privileges with UA and I ride them often. However, I've never jumped to Canada.

Do you just go to the gate like you do for UA domestic? I'm assuming if it's full you are out of luck? Not sure about the actual JS domestic US to Canada. If anyone has access to the loads, that may help greatly with my decision. Thanks!
