If you arrive from Canada with a boarding pass and for a connecting flight to an international destination, you don’t have to leave the restricted area or be concerned about your checked luggage.
Please note that if you do not have your boarding pass, you have to get one at the check-in counter for your airline or at the self-service kiosks.
Consult one of the flight display screens for your gate number and keep your boarding pass ready to go through security at the entrance to the international zone. Once you have entered the international zone, you cannot return to the mixed zone.
If you want to leave the restricted area, remember to have your boarding pass and passport with you and to present yourself well in advance at the security checkpoint for your departure.
