If you are flying in their higher Freedom class, you are permitted to check two bags at no cost. It may make more sense to try and fit everything into acceptable carry-on items as Porter allows two carry-ons per passenger, up to 20 pounds each. The maximum dimensions for the two carry-ons are 55 x 40 x 23 and 33 x 43 x 16 (all in centimetres).
