I'm in Winnipeg and may take the offer of carpooling with my friend and her family crossing the US border and catching our flights to US destinations. I may book 2 separate one-way flights to save money. I'm going to Dallas TX while my friend and her family are flying to LAX. We're both going on vacations and I've got a Mavericks and Stars game tickets. They are going to park their car in Grand Forks. Later on, I'll be flying home back to YWG while my friends will fly to Grand Forks and then make the drive back up to Canada.
Is it possible be denied or experience extra scrutiny at the US border because I'm taking the flight back home and not riding with them? I'm sure they keep a record of the number of passengers in the car crossing into the borders. I don't want the border staff to think my friends are transporting illegals since there will be 1 less in the car upon the return to Canada.
