Air France's cabin bag allowance sits at 55x25x35cm for hand luggage placed in the overhead locker. It's a standard European allowance, and several Flight Knight sizes fit comfortably within those dimensions.

Air France generally includes a cabin bag with economy tickets, though your exact entitlement depends on your fare and route. Domestic French flights and some European routes may have slightly different rules, so it's always worth checking your booking before you travel.

For the sizes that work with Air France, you've got options from a compact underseat bag all the way up to a solid 55x35x25 overhead case - enough packing space for a long weekend in Paris or a week-long trip further afield.
