If you'd like to know what you can bring on board with you and in what size bag, our carry-on baggage page will help you pack smart.

Wondering about maximum baggage size and weight allowances for the bags you plan on checking in at the baggage counter? Visit our checked baggage page for all the details on important restrictions and regulations.

And if you've got a question about travelling with special or oversized items, you'll no doubt find the answer on our sports equipment, hunting equipment, musical instruments or additional checked baggage pages.

If you're travelling with very young children, formula, breast milk, juice and baby food (in small containers) are permitted in carry-on baggage. To keep these items at the desired temperature, we encourage you to bring them in a small cooler and request extra ice as needed since onboard refrigeration may not always be available on all aircraft types. View more practical tips on travelling with young children.

If you need to bring medication along with you, always pack it in your carry-on baggage. All prescription medications must be properly labelled with the names of the patient, the medication, and the issuing medical office or pharmacy.

For useful information on types and quantities of liquids and gels permitted on board, view our Reminder to Travellers (pdf file, 267 KB) in the Security Enhancements section of our carry-on baggage page, or visit the Canadian Air Transport Security Authority (CATSA) website.
