Understanding the Carry On Luggage Air Canada policy helps travelers prepare for a smooth and convenient journey. The airline generally permits one standard carry-on bag measuring up to 21.5 × 15.5 × 9 inches, along with one personal item measuring up to 17 × 13 × 6 inches. However, certain Economy Basic fares restrict passengers to one personal item on select routes. Carry-on bags must meet the applicable size requirements and fit securely in the overhead compartment. Before departure, review your ticket conditions and current baggage guidelines to avoid unexpected fees and enjoy a stress-free travel experience.
