Air Canada (AC) Baggage Allowance Calculator

Carry-on rules on Air Canada (AC): no formal weight cap, dimensions not exceeding 55×40×23 cm (L×W×H). Air Canada's carry-on policy leans on dimensions rather than weight: 55×40×23 cm, enforced by the gate sizer.

A small personal item (purse, small backpack, laptop bag) is also permitted on Air Canada provided it fits under the seat in front of you.

The checked allowance on Air Canada is 23 kg per standard bag, and the $30 fee doubles at the airport counter. The linear dimension limit (L+W+H) on Air Canada checked bags is 158 cm.

Each additional bag beyond the first runs $100 USD pre-booked online. Bulky items like strollers, car seats and wheelchairs travel free in the hold on Air Canada, and overweight charges kick in above 23 kg at $10 USD per additional kilogram.

Two fee lines dominate a Air Canada excess bill: $100 for each additional checked bag and $10 per kilogram above 23 kg. A 28 kg bag on Air Canada's 23 kg allowance costs $50 in overweight charges alone — the table below compares that against simply adding a second bag at $100.

Pre-book additional bags online — airport-side rates on Air Canada are 40–60% higher, and same-day changes at the counter may not be available at all.

Skis, golf clubs and bikes count as ordinary checked bags on Air Canada up to 23 kg; oversize items above 158 cm linear may incur a flat $75–150 surcharge. Guitars and cellos are the awkward case on Air Canada: either buy them a seat or check them in a hard case — soft cases are not covered for damage.

Strollers, car seats and mobility devices (wheelchairs, scooters) travel free on Air Canada with priority handling — gate-check a stroller and it returns at the aircraft door.
