The product description has the dimensions at 29.5 by 19 by 11.5.  The actual dimensions (not counting the wheels or handle) are 29.5 by 19 by 14.  That totals 63.5 inches without anything in the outside pockets.  Most airlines limit the size to 62 inches.  In addition the weight is 14.2 pounds so you only have 35.8 pounds for yourself.

It is a very nice suitcase for traveling by car, but too big for air travel.
