WestJet charges
between $ 20 and $ 23 for a second bag on most routes, while Air Canada charges economy - class flyers $ 20 for a second bag within Canada and $ 25 for a single
piece of checked
luggage on flights to the U.S. Not surprisingly, the aisles
of many flights now resemble a war zone as frantic passengers search for an overhead bin into which they stuff their bulging carry - ons, slowing down boarding times.
