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.

Pre-board Screening

At airport security checkpoints across the country, security screening of passengers and their belongings is conducted by CATSA’s screening officers prior to their entry into the secure area of an airport.

Screening officers use a variety of screening technologies and procedures to prevent passengers from carrying prohibited items beyond the screening checkpoint.
