The RAIC system, created by CATSA in partnership with Transport Canada and airport authorities, uses iris and fingerprint biometric identifiers to allow non-passenger access to the restricted areas of airports. The final authority that determines access to the restricted areas of the airport is the airport authority itself.
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.
