Carry-On Size Limits. All passengers on American Airlines flights, regardless of class, are allowed one carry-on bag, which can weigh up to 40 pounds. Carry-ons must also not exceed 45 linear inches; this is the sum of the bag's height, length and width. Alternately, you may bring a hanging garment bag in the place of a standard carry-on.
