Like Delta, Air Canada has no weight limit for carry-on luggage. Take advantage of this by packing heavy books, gear, and toiletries in your carry-on, leaving your checked bag light.
Best bag selection: Choose a hardshell bag that has a built-in pocket for your laptop to easily retrieve it at security.
