Security Screening Wait Times

CATSA encourages all passengers to arrive at their departing airport well in advance of their flight. Many airlines advise passengers to arrive two hours in advance for domestic flights and three hours in advance for US and international flights.

How are wait times calculated?

Wait times for queues at security screening are calculated through the scanning of boarding passes when you enter the beginning of the queue, and once again, before you begin your individual screening process.
